Jamaican Stone – Is The Strength Worth The Danger?

photo of 3 pieces of jamaican stone

Jamaican Stone is one of the more unusual ways to last longer during sex that I’ve tried.

But not only is it sold as a way to have longer sex, but it’s often advertised as giving stronger erection too. However, the phrase ‘too good to be true’ might apply in this case.

It was banned by the United States Food and Drug Administration after someone died from eating it. And the ingredients have been found by researchers to be potentially dangerous (more on that below).

Having said that, it’s still a popular product in a few communities around the world, where some men swear by its potency.

So in this Jamaican Stone review, I’ll cover both my experience using it and some useful background information about the safety concerns.

What is Jamaican Stone?

Jamaican Stone is sold as a sexual performance enhancer. It’s said to be harvested from the tree sap of a tree native to Jamaica and some other Caribbean Islands.

It’s then molded into the stone from which you can see in the image above. The standard size is between 0.5 and 1 inches.

It’s also known as Jamaican Black Stone due to the color of the finished product, although it’s possible to find it in other forms, such as drops or gels.

Strangely, nobody seems to know the name of the tree it comes from. It doesn’t say on the packet, and no supplier website mentions the name.

And here’s the worrying part – after it caused a death, it was reported that some versions contain toad venom from the Bufo genus.

Apparently, both the toad venom and the tree sap contain chemicals known as bufadienolides, which can disrupt the normal rhythm of the heart. So no matter where it comes from, it doesn’t exactly seem the safest option.

How to use Jamaican stone

  • Apply a couple of drops of water onto one surface of the stone.
  • Rub the water on the stone in a circular motion until it turns into a milky colored liquid.
  • Gently rub that liquid onto the sensitive parts of your penis. Concentrate on the head as this has the most sensitive nerve endings.
  • You’ll need to test exactly how long you need to wait before having sex. It could be anything from 10 to 30 minutes, so some experimenting is needed.
  • Before you have sex wash off any excess liquid with some mild soap.
  • Dry the stone and store it. It can last for several months if you care for it properly.

My experience

I couldn’t find any scientific research into the effectiveness of Jamaica stone for premature ejaculation, so I was a little in the dark when testing it.

I ordered it online and it arrived a week later in an unmarked packet. I followed the instructions above, though didn’t get it quite right the first time.

A common problem with desensitizing products is working out how much you need. Apply more than you need to, and you risk numbing yourself too much; too little and it won’t work.

I had an unpleasantly hot sensation which took around 15 minutes to subside after washing it off thoroughly. And it probably took another 30 minutes for the tingling sensation to go away completely.

The second time, I was more careful and just rubbed a couple of small drops on. This time there was still a hot tingling sensation, which again took a while to subside, but it was more tolerable.

It seems to take about 10 minutes to have a noticeable effect, but 20 to be at the maximum desensitizing potential.

The numbing effect was definitely effective, and there’s no doubt that using Jamaican Stone allowed me to have sex for longer. However, it wasn’t as long as the 4 hours some sellers claim.

Did it have the other effect of giving me a stronger, harder erection? Not as far as I could tell. Maybe that part is a marketing gimmick, or maybe it just didn’t work on this occasion.

The numbing did last for several hours, which was much longer than most other delay products I’ve tried, which tend to wear off in a couple of hours.

Possible issues and side effects

  • The main side effect is the burning sensation if you put too much on.
  • Even when you get the amount right, you still have to put up with a hot tingling sensation.
  • It’s not a good idea to use Jamaican Stone during oral sex because of the dangers of eating it. It also has an unpleasant taste.
  • The numbing sensation is strong, so could reduce the pleasure of sex.
  • The risk of serious harm – see the following section.

Death reported in the news

jamaican black stone

In 2008, many U.S. news outlets (such as ABC), reported that the New York health department was warning people not to use Jamaican Stone. This was apparently because a man died after eating it.

The warning also reported that similar versions were behind poisonings and deaths in the 1990s. Obviously, it’s not meant to be eaten, but they do further warn that even applying it to the skin can be harmful.

In 2017, researchers published a report of a case of a man who died of heart complications after ingesting the stone.

Update – some clarity regarding the ingredients

In 2017, Spanish researchers undertook a rigorous scientific analysis of Jamaican Stone to identify the exact ingredients.

They concluded that it has toxic ingredients and described it as a ‘dangerous aphrodisiac’. You can read their full research article here.

Problems buying online

Following all the comments from readers asking where they can get it, I did some research into the online sellers.

I encountered one problem after another, mainly with security warnings about the websites and payment systems with low review ratings.

My personal view is that this product should be avoided, especially as there are safer alternatives.


There are alternatives that don’t present the same problems as Jamaican Stone. If you’re interested in trying a desensitizing product, I recommend taking a look at my overview of delay sprays.

Your experience

Please feel free to share your experience with Jamaican Stone in the comments. But please don’t ask me where you can buy it, or leave links for online sellers, as I no longer publish those kind of comments.

  1. Used this while in the usa years back, it actually trained me to the extent that when I don’t use it I still last for ever, but not all women can take it, I am saying you will go on for hours. perfect product.

    1. Hi Kay
      I guess maybe it gave you some confidence when using it which might have helped get over a psychological issue that was causing the PE, because there’s no evidence at all that any desensitizing product can have a permanent physical effect on lasting time!

  2. hi, ethan…i have no erection problem..but i have premature ejaculation problem..if i use black stone…how longer i can stay before ejaculation.

    1. Hi John
      There’s no way to predict exactly how much longer you’ll last. You’ll only really know the answer to that question when you try it. Sorry I can’t be more specific!

  4. Yah it works well! I just want to ask is black stone is a drug? Im going home this coming 20 and my flight is in us counrty

    1. Hi Kro
      I don’t think it’s considered a drug. However, it is banned by the FDA in the US. I’m not totally sure if you’re allowed to bring it into the country. I just had a look online and couldn’t find a definitive answer. I’d do some research if I were you before thinking of taking it with you.

  5. I work in a cruise ship, i bought it in carribean seas at st maarten. Most of the crew member use it especially when going to carolina!

  6. Hey,
    Good article, I have been using stone back home in the Caribbean for over 30 yrs.
    Lots of men back there use it.

    By the way do you mind sharing the link with me, for where you bought yours.


        1. Does the numb means the product will work even if I have poor erection. Don’t mind my questions, just wanted to be on safer side.

  7. Dear Ethan,

    I have a serious problem of premature ejaculation ?. I always come very fast.

    For the first time I tried this stone. I wet my finger tip, rubbed on the stone for few seconds and applied the glue like on the tip of penis. I applied a little only.

    I waited for one minute and didn’t feel any burning sensation at all. I washed penis and went to sex, but again came fast. I don’t know what the problem is. Am I doing anything wrong or the stone is not genuine…?

    Please help me……???

    1. Hi Jaffy
      It could either be because it was a fake, but more likely it just doesn’t work for you. No desensitizing product works perfectly for 100% of guys unfortunately. So it’s sometimes a case of trial and error until you find one that works. Equally, for some guys, it’s just not the right answer full stop. So you might be better off trying to control your arousal levels naturally rather than the physical sensitivity option.

    2. Hi Jaffy, did you say you waited for just a minute and the penis for sex? No man, wait for at least after 35 min. Do not rush for sex. Relax completely. Take your mind off “the match”. I also think if No heat on the penis after you have applied the liquid and waited then NO effect. By the way any help I really need some in Ghana. tkx

  8. Hi I’m Von
    I read all the comments. The stone works better than anything I’ve ever used . I live in Atlanta Ga. I’ll like to know a retailer in Georgia or in the US.

    1. Hi Von
      Thanks for your comment. If it works for you, then great! I don’t know any specific retailers there. You’ll probably have to find a website you feel looks trustworthy.

  9. What’s the difference between Jamaican stone and Jerusalem stone . they are both called black stone right are they then the same??

    1. Hi Dichi
      I’ve never heard of Jerusalem stone as a desensitizing sex product, which to me would be the difference. Did you find a website or shop selling it as such?

  10. hi i am using this jamica stone but i used only one drop of this i having lot of burning sensation to my head of penis and where it will touch it that’s also getting burning sensation. how can i reduce this sensation immediately.

    1. Hi Mouttou
      Sorry to hear you’ve had that reaction to it. Presumably by now you’ve managed to find a way to reduce the burning. But if not, I’d get some doctor’s advice. I also wouldn’t recommend taking it again if you’ve had that reaction to it with just one drop.

  11. Bought a small stone in a sex shop in Amsterdam about 8 years ago. Works wonders. The stone is now about a quarter of its original size. I use a very small quantity of hot water in a glass and put the stone in for about 30 seconds. I then rub the stone on the head of my penis for another 30 seconds. If I wash off after 5 minutes with soap and water it works great. If I leave it on for 15 minutes it is really hard to cum… takes forever.

    1. Hi Ray
      Thanks for your comment. It’s always interesting to hear people’s stories. I think the idea is to rub it on with your hand, not directly on. That might help reduce the extra numbing!

  12. hi ethan.

    i am from malaysia, the borneo side of it not the peninsular, here we have a product similar to that black jamaican, it basically do what the black jamaican can do, and also the same side effect. we call it GAMBIR SARAWAK. but it is much safer than black jamaican, and it helps with the erection, when i use it last night, i had sex an hour with my wife,i am happy i was able to make love to her that long.

    today, we will do it again, and i will try up to 2 hours this time.

    1. Hi Calelthan
      Thanks for that idea. I don’t think Gambir Sarawak has the best reputation ever, but if it works well for you, that’s all that matters.

      1. Hi im 28 years old im going to get marry I have problems erection very soon it good to use Jamaican store are gambir sarawak but in gambir sarawak website it is telling good to use gambir Sarawak then Jamaican store

        1. Hi Pasha
          I haven’t personally used Gambir Sarawak, so I can’t help much I’m afraid. However, I’d suggest looking for reviews rather than only trusting what the seller’s website says.

  13. Hi Ethan,
    When I was in my 30’s my friends and I used it and no one complained about it other than the burning sensation and everybody said that they lasted much longer. The same for myself.

    But whilst in Holland, I saw it being advertised for sale, but they had sold out of it. The owner of the store said that it can cause cancer and therefore I have never used it again.

    My friends and self only stopped using as we could not purchase it anymore, I have been to Jamaica several times in the last two years and can not get it.

    1. Hi Dunz
      That’s curious about the owner stopping selling it because of the risk of cancer!
      I haven’t bought it for some time now, and when I did I ordered it online from a wholesalers. My advice would be to google it and check out the top few sites selling it and make a judgment call yourself on how trustworthy they seem.

  14. hi there,
    i bought it from Panama,right now. but im still not clear to use this black stone properly and correct amount to apply. one more things is to apply on the penis or penis head?
    Dear Ethan, could u reply to me clearly?

    Many thanks

    1. Hi Paing

      Ok, so do this:
      1) put a little water on the stone and rub it lightly with your fingers until a kind of film/residue appears.
      2) take that residue and rub it onto the head of your penis (not inside the opening though).
      3) After 5-10 minutes wash it off, wash your hands well also with soap.
      4) If you feel a hot sensation, you know it’s working and can start having sex.

      Hope that helps

  15. Hiya readers, I need advice on this because I was given a Jamaican stone by a friend and apparently it is illegal to have it in your possession according to the Army because it contains bufetaine. Is it Illegal in the United Kingdom. Army trying to charge me for it.

    1. Hi Prof Liquid

      Sorry to hear you’re in such trouble! As far as I’m aware, Jamaican Stone isn’t illegal in the UK. But bufotenin is a class A drug. So presumably if you have some as part of another product, it might be considered illegal. To be honest though, I’ve not heard of any cases like yours. Perhaps one of the other readers following these comments will be able to shed more light on it.

  16. Hello Ethan,
    I found your review while looking to find out if Jamaican stone is poisonous. Your review is very informative thank you for it. I have tried it and it made me last for hours. All I needed was some energy drink to keep me firing. Jamaican Stone and other similar products don’t keep you hard or bigger like sellers say. They only reduce over-sensitivity so you don’t come quickly. The rest is in the mind, how turned on you are and how sexy your partner might be, etc. As long as you have something to keep you turned on, you can ride on for a while.
    Let’s also note that we react to things differently, hence our different experiences. Fortunately, I’m Black, so even if my penis turns red, I can’t tell. It gives some uncomfortable feeling, though. Especially if you keep it on for too long. It remains one of the best numbing agent I’ve ever used. I also feel its effects after 24hrs sometimes.

    1. Hi Kallu

      Thanks for your comment, and it’s always good to hear from people who’ve had good experiences as well as bad. Thanks for adding the info. about it not helping with all the things sellers say it does. That’s my belief as well – that really, it’s a numbing agent and no more. And you’re absolutely right about people having different experiences. That’s one reason why finding a good desensitizing product needs a bit of trial and error – albeit carefully!

  17. hi i used this Jamaican black stone for the first and last time and wont use it again. after i have used this thing my heart rhythm changed crazy. i thought i was going to die because my heart was pumping too fast. after 24 hrs i still feel something wrong with me. i cum still late and dont feel the same as before. i want to know when this thing completely over with me. when how long will it take to loose its sensation?

    1. Hi Veli

      It could be that you had an allergic reaction to it. I know it’s a while since you posted this comment, but I would suggest not using it again. And perhaps speak to your doctor if you’re still not feeling right, though hopefully you will have long since recovered.

  18. After applying the Jamaican stone correctly, what is the extra amount of time one could wait before engaging in sex? What if one doesn’t have sex for about 12-24 hours after the correct application of the Jamaican stone?

    1. Hi Shatta,

      Thanks for your comment. Firstly, Jamaican Stone will not work after 24-48 hour of applying it. I think if you wait 2-3 hours, you may even be pushing the limits of how long it will work for. Normally it’s best to apply it just before you are going to have sex.

  19. Ethan I would like to know if It is safe to use the Jamaican stone if my wife is pregnant. I was reading thru the comments but didn’t see the topic come up

    1. Hi ogm
      My standard advice for ALL delay products is not to use them with a pregnant woman unless wearing a condom. In the absence of extensive medical advice, it’s better to be safe than sorry.

  20. i used the stone about 8 years back when a friend shared it with me and i can testify its just the best you can ever get for longer erection. Are the ones sold online genuine? I need to get it back again. I am in the US now.

    1. Hi Slicky,

      Thanks for your comment. So you found it helped you have an erection for longer? Interesting. I imagine that like most things online these days, some are real and some are fake. If you google it, you’ll find some of the main distributors.

  21. Hi steve I had used the jamaican stone follows the instruction that step by step the product mentioned.
    A well my penis getting red and numbness, wait for the time and as result…it does not erect and strong for my couple penetration it is embarrassing for me. I have tried for 3 hours and nothing happens.
    What can I do?
    What is your recommendation?
    Does sexual stone work under stimulation or without it?
    I have 45 year old.
    Please let me know.

    1. Hi George,

      Thanks for your comment. It may be that Jamaican Stone just isn’t quite right for you. If you can’t get an erection with it, and your penis is red, then that doesn’t sound right. Perhaps you put too much on, even if you did try to follow the instructions. Maybe try a different delay product.

    I have taken the liberty of putting your spanish comment into google translate, since most readers are English speakers. I will publish that immediately below, and your original Spanish version underneath.

    We recall once our fifth grade teacher told us that “the difference between the remedy and poison is the dose.” This is because for our body everything in excess is bad (food, water, heat, cold, medicine, even sex), the same principles apply here. We say YES to some extent, overuse of Jamaican stone can cause severe burning sensation in the penis and cause the skin to peel or irritate. Therefore it is important to regularly remind our customers that start in this world, FOREVER must start with a low dose (3-4 drops and 15-20 minutes) for each application is more than enough, we should not apply too much liquid and not leave it for a while, of course this if the first time, follow all the instructions and see how it goes, as particular cases there are people that high amounts of Jamaican stone apply and the leave taking effect by More than 1 hour, which may result in a higher benefit for a person, but dramatically bad for others. If after several uses we realize that there is no allergic skin reaction, can proceed with the increase in dose to the level that works optimally for you.

    For all these stone would say Jamaica is a safe product that has been used for centuries as long as DO NOT APPLY TO OTHER DIFFERENT BODY of the glans penis. In fact, we know that the stone has been used traditional, ironically, to improve healing after burns, to treat pain caused by snakebite, to treat toothache, these being practiced today in some Asian countries .

    Recordamos una vez que nuestro profesor de quinto grado nos dijo que “la diferencia entre el remedio y el veneno es la dosis”. Esto ya que para nuestro cuerpo todo en exceso es malo (comida, agua, calor, frio, medicina, incluso el sexo), los mismos principios se aplican aquí. Debemos decir que SI hasta cierto punto, el uso excesivo de piedra jamaicana puede causar severa sensación de ardor en el pene y causar que la piel se pele o irrite. Por esto es importante que le recordemos regularmente a nuestros clientes que se inician en este mundo, SIEMPRE debemos iniciar con una dosis baja (3 a 4 gotas y de 15 a 20 minutos) para cada aplicación es más que suficiente, no debemos aplicar demasiada cantidad de líquido y tampoco dejarla por mucho tiempo, claro esta esto si es la primera vez, recomendamos seguir las instrucciones y ver cómo nos va, ya que para casos particulares existen personas que se aplican altas cantidades de piedra jamaiquina y se la dejan haciendo efecto por más de 1 hora, lo cual puede resultar en un alto beneficio para unas persona, pero dramáticamente malo para otras. Si después de varios usos nos damos cuenta de que no hay ninguna reacción alérgica en la piel, pueden proceder con el aumento de la dosis hasta el nivel en el que trabaja de manera óptima para su caso.

    Por todo lo anterior diría que la piedra de Jamaica es un producto seguro que se ha utilizado durante siglos, siempre y cuando NO SE TRAQUE O APLIQUE EN OTRO ORGANO DIFERENTE DEL GLANDE DEL PENE. De hecho, sabemos que la piedra se ha utilizado tradicional, irónicamente, para mejorar la cicatrización después de quemaduras, para tratar el dolor causado por la mordedura de serpiente, para tratar el dolor de muelas, siendo estos practicados en la actualidad en algunos países Asiaticos.

    1. Hi Jslatam

      Thanks for your comment. I think you give good advice there about starting with a low dose, and first ensuring that you don’t have a bad reaction to the product. In fact, that’s good advice for any delay product which is applied directly to the skin I think.

      I’ve never heard of Jamaican stone being used to help burns though. Can you provide a link to a site with some evidence of that?

      Many thanks

  23. i have one piece from a jamaican that used to be my co-worker. I kept it for more than 1 year until i got the chance to try it.
    i used only one time and it worked from the first shot.
    there is a small burning/numb sensation but nothing that is going to kill you :-)
    extended size of penis or longer erection – i did not noticed… the purpose of the stone is to kill temporary the nervs/sensation in penis head (the most sensitive part of our tool) that makes you cum later… as you do not feel too much the excitation
    that’s it.
    do not forget to wash it off 5-10 minutes after applying… better wash it 2 times to make sure…
    if you forget to do-it… you are in biiig trouble as the numb sensation is transmitted to your partner as well… and than… you have to work like hell to make her cum!! hahaha

    1. Hi friendxx,

      Thanks for your comment, and for the important advice about how to properly use Jamaican stone. It’t good to have those messages reinforced by a reader.
      You’re absolutely right about it being very important to wash off properly, both for your sake and your partner’s!
      All the best

    1. Hi,
      You should search online for a retailer who distributes in, or to, qatar. We only do reviews here, so you’ll have to do that research using a search engine like google.
      All the best

    1. Do you feel any sensation while having sex when using the Jamaican stone?

      By the way, I used Optimale twice so far, but it didnt work so far.

        1. Hi Ethan

          Thanks for your reply

          I think I will go ahead and order Promescent

          Just to let you know your amazon link for Promescent doesnt work

          I went to the Promoscent website and I tried to order for Canada but it had a glitch and kept telling me to choose a shipping option when I clearly had

          And their contact number says its not in use.

          From what I have read online, I think Promescent could be an improvement for me

        2. Hi there,

          Thanks for your comment. Ive just checked and it seems it’s no longer being sold on amazon, which is why the link didn’t work. Thanks for letting me know! I guess their site was just temporarily down. I’m sure you’ve tried again though in the time it’s taken me to reply to your comment!

  24. Hi,

    I’m writing from England, when i used to live in Jamaica, stone is what man love and ladies hate, man sing praise to it for all night action, I’ve never use stone itself but i use a condon called LONG LOVE, this condon meant to have a small amount of liquid stone in the tip, I have a mild burning sensation and tingle but i did last for over 4 hours.

    how I’m in a serious relationship and about to get married i cannot use a condom with my lady, and tho i already have a very high sex drive a rarely last over a hour with her, so I was back at it again! my experience is if the black stone is as good as the liquid stone in the long love condom i would recommend it to my grand dad. after all the race is not for the swift!!

    1. Hi Jermome

      Thanks for your comment, and it’s great that you found something which worked for you. But if you say you rarely last an hour, it sounds like you are still lasting a very long time! Maybe you don’t really need any extra help…


  25. Had horrible experience with stone drops. Is very difficult to dose right and hard to predict how it will work. I did it couple of times. First time had quite a burn, did have sex, and could go on long time, but was burned for almost two weeks, scary period, but healed. I later on did it for a second time, again a burn, but I did less, and the burn was less. Sex went fine. And last time I did some one, also not much, few drops, washed as the instructions told, thoroughly and forgot about it. Went to sleep hours later, woke up in the morning, penis head was totally numb for a total of 20 hours or more! No feeling whatsoever!!! Very scary! Than feeling came back a bit, but burned my head very badly, so burning feeling red penis head. And it took 2 months before feeling came back more. Now 4 months further. Not sure if feeling is totally the same though. But that might just be in my head. I say, that stuff is dangerous. Don’t try it. Try something more mild, although not sure what that it. Good luck!

    1. Hi Pete,

      Thanks for your comment, and sorry to hear you had such a bad experience with Jamaican Stone. That does sound extremely scary. I think I would have stopped after the first bad experience though!
      I know that getting the dose right can be an issue with all delay products, but it’s a shame that if you get it very wrong with this one it can cause such problems. yours does sound like quite an extreme example, so perhaps either you’re particularly sensitive to it, or really did get the dose and washing process wrong.
      But whatever happened, it’s still a valid warning for other guys to be careful if they use it. And of course another good reason to avoid delay products altogether and go down the natural techniques route, which is my personal recommendation.
      I hope you find a way to last longer which works for you, and that the feeling returns to normal soon.

  26. Hi guys I just bought Jamaican stone and that’s the best. But my only concern is it legal to have them on your pocket in those countries…Finland,Sweden,Switzerland. it’s cos am planing to go there in the next few weeks and I don’t want to take the stone with me if it’s illegal up there. thank you for your time.

    1. Hi Tommy,

      Thanks for your comment and I’m glad you’ve found something which works for you. I don’t know if it’s legal in those countries or not. Perhaps someone who is following this comment thread will know.


  27. So I finally began reading the book you recommended “The Ejaculation Trainer”

    I am only 20 pages in and it explains very well the nature of PE, why PE happens and so on.

    Understanding the problem is always the first step.

    Anyways….Has the content in this book solved your problem Ethan? Or do you just recommended it because you know its good. (There is nothing wrong with promoting it, even if you have not used the book yourself)

    I know it will take time and effort to follow everything in the book and actually train your body and mind to help you solve PE

    Does anyone else have any experience with this book?

    1. Hi Harvey

      To answer your question in the most honest way possible, yes, I believe it was a major part of solving my problem. But at the same time I’ve also spent a lot of time researching the problem, especially since I have a blog dedicated to it!

      I imagine a more useful question for you would be ‘do I believe that the plan in the book on its own can solve the problem for any guy?’ And the answer to that is that I think it could for the majority of guys, though of course there will be a few exceptions. Perhaps guys who have the problem due to things beyond their control, such as medical or deep psychological problems which require medical or psychological help.

      That said, I recommend it both because I believe it’s the best book on the subject (though ejaculation by command is also very good), and because I’m pretty sure that it made a big difference to my own lasting time. This was in part with all the tricks and techniques that it gives you that you can do immediately, but also because of all the background info. (as you mention) and the subsequent techniques for developing control.

      I think the key though is you. If you’re willing to take on board the advice, and practice the exercises diligently and consistently, then you have a very good chance of overcoming the problem.

      Perhaps someone else will also comment, since you’ve asked the question of other readers:-)
      All the best, and please do follow the program through – it will definitely make a difference. Just how big is partly how much effort you’re willing to put in.

  28. Had some pretty good experiences but the burning sensation is definitely there when you leave it on too long and has been instances when I still climax without a delay from not leaving it on long enough. Also drank every day during a vacation while using Jamaican stone and couldn’t climax for the first 9 days straight

    1. Hi usarmy6440

      That’s the thing with all desensitizing products – you need to get the amount just right. So it’s worth experimenting and making a clear note in your head of how much works – exactly how much!
      And yes, alcohol is known to help men last longer, sometimes until you or your partner gives up, especially if combined with a desensitizer. Again, it can be a useful tool, but you have to get it right. I’ve found 2 or 3 beers helps a lot, but any more and I have problems like that too.
      All the best

  29. I had I terrible experience with it..I use the stone but failed to follow the instructions…I didn’t wash it off..after some time I felt serious burns.I later washed it but when when I woke up from bed I found a painful cut on my penis.

    1. Hi Jonson

      Sorry to hear that – it sounds very painful! Did it heal eventually? It definitely highlights the importance of following the instructions for this, or any other delay product.

      Wishing you well if this was a recent incident…

  30. Thanks for your helpful review that got me well informed and so educated just now. U are the first person making me hear of the Jamaican Stone for the first time in my entire twenty-five years of living.
    Am very glad and I love just everything about your review.
    I would try it pretty soon and also give my share of experience to you.
    Thanks and keep the good work.

    1. Hi Alex Oz II

      Thank you for the comment, and for the compliments. I’m very happy you found the review useful. It would be great to hear from you once you’ve tried it, so please do come back and tell me, and other readers if it worked well or not.

  31. Hi Ethan

    i stumbled onto your blog after looking online for “herbal, natural” delay sprays.

    I found a jamaican stone that comes in spray form, but after your review I may ‘delay’ :) using it .

    But I found this delay spray called Optimale delay spray by Doc Johnson (not a plug, I promise). It says on the site that its ‘naturally derived’

    Have you tried this? Is it better than Stud delay spray?

    Any info would be helpful


    1. Hi Harvey,

      Thanks for your comment, and I understand wanting to think twice about Jamaican Stone.

      I think the Doc Johnson Optimale spray is a new one. I can’t see any reviews for it on any of the major sex product websites even though it’s listed on a few.
      Interestingly on their website they don’t list the ingredients. But on the Adam And Eve website they do, which are: Lidocaine, Cannabis Sativa Seed Extract, Diazolidinyl Urea, Disodium EDTA, Ethoxydiglycol, Idopropnyl Butylcarbamate, Propylene Glycol, Sodium PCA, Water (Aqua).
      Lidocaine is not something which is naturally derived, and is in the majority of delay sprays, so I think they are alluding to one or two of the other ingredients. It seems a bit of a marketing thing to me. I might give it a go at some point, but there are so many new ones popping up all the time, to be honest I can’t face trying them all!!

      1. Hi Ethan and Harvey,

        I stumbled on this article looking for more info on the Jamaican Stone after a client told me about it (I’m a saleswoman and buyer for an erotic boutique in Montreal, Canada). For the OptiMale spray I can tell you Lidocaine is the active ingredient, same as with the Stud 100, if the concentration is more than 9.6% (the concentration of the Stud 100) then yes in theory it should work faster and last longer, if not then probably not. Don’t be fooled by marketing schemes, every brand of sexual enhancement products will tell you what they think you want to hear to make you buy their product over that of the competition (and there is a LOT of competition). I’ve learned this in my many years doing this job, forget what they tell you (besides what it’s for of course) and focus on what makes the product work. Lidocaine is a numbing agent which absorbs into the blood stream, this allows it to be more effective and last for longer periods, compared to a Benzocaine based product (same stuff they use in Orajel). A few things to be mindful of with Lidocaine based products: if you have any issues that revolve around the heart or the blood, do not use it. You must wash it off after 15mins max to avoid numbing your partner. And finally, if you are trying to get pregnant, if your partner is pregnant, or nursing, do not use it! Even after washing, the product has entered your skin and blood stream, washing will only remove the product from the surface and avoid transferring numbness, but it can still absorb into her blood stream through contact.
        Good luck guys, hope my info helped you, be safe and have fun :) I just wish I could find more info on the ingredients in Jamaican Stone :/ would be good to know if its been banned by Health Canada as well as the FDA as mentioned in your article.

        1. Hi Sammy

          Thanks for you comment, and the useful information about Lidocaine, which is of course the main ingredient in a huge number of desensitizing products. (Just for the record of anyone reading though, Jamaican Stone doesn’t contain Lidocaine).

          You’re right of course about marketing, and it’s the case for most products whether in the sexuality industry or any other!

          I can’t help you on the Canadian question I’m afraid, but if you do find out, please pop back and let us know if you have a minute.


  32. Hello,

    I’ve used the stone for years with no ill effects, with the exception of using too much or not washing it completely off. I mainly use it when a “thrashing” is called for. But everyone’s body reacts differently to different products, so what some can tolerate, others can’t.

    The store I used to get it from changed ownership and it is no longer available locally so I’ve been trying to find a reputable vendor online or within a not too distant drive.

    I hope that you get a chance to test it again with better results. And as for the erection, no, it will not be physically longer or larger. Personally, depending on who I’m with and the state of arousal generally dictates the amount of swelling that takes place. I’ve gone 4-6 hours easily without climaxing which is great for making sure your partner is satisfied.

    Again, hopefully you will get another chance to use it with better test results.

    1. Hi SirTapout,

      Thanks for your comment – it’s good to hear from someone who has had a positive experience. It’s interesting that you found it helps delay climax, but isn’t so effective on the longer or larger erection front. I think your comment about it depending on the person is very true, and something I try to remember when writing reviews.
      I will try it again possibly in the future, but don’t have any plans to just yet!

  33. the stone is the best performance enhancer ever. I’ve been using it for years the thing is it’s for the living not the dead so dont expect resurrection …

    1. Hi Powerstone,

      Thanks for the comment. Can I ask, if you’ve been using it happily for years, what brought you along to read a review of it? I’m always curious when people do that. Was there something in particular you wanted to know about?


  34. Hegir Takarima

    I tried using Jamaican stone and followed diligently the instructions on how to use it. I noticed a warm-like tingling sensation at the head (glans penis) where i applied it but at the same time a ‘redness’ at the exact area where it was put on, and that’s even after I washed it off, just less than 3 minutes after applying it. The redness gradually disappeared after 2-3 days, but now (it’s already 3 weeks since then) there’a dark discoloration and wrinkling at the exact spot where it was applied. BTW, I only used it once and never again, I threw away the ‘stone’ after that incident. What happened? Is this discoloration on the glans penis that has not disappeared for 3 weeks now a cause for concern? Thanks.

    1. Hi Hegir Takarima

      Thank you for your comment and sharing your story. I am sorry to hear that it is an unpleasant story though. To be perfectly honest, I really don’t know how much of a concern it should be that there is discoloration and wrinkling as you describe it. I imagine it’s possible that it could improve naturally with time, but then again I am just guessing from what I have read on other websites and my own experience.
      Personally, if it was me, I would get it checked out by a doctor just to be absolutely sure that there is no permanent damage, and of course to get some advice on something which might help it return to normal.
      I hope it does get better, and please come back and let me and other readers know what happened. That would be really useful.
      Thanks and all the best

  35. Thanks for these review guys really appreciate it. Wanting to try it for a while now just wanted some good feedback. Just one question though to Ethan Green, seeing it’s your article, and don’t get me wrong I really do appreciate the article. Is your verdict still to stay away from Jamaican Stone? Seeing now that the crucial issue was on how it is being used and not the product it self. Mark you, that even LongLove condoms can give you a horrible experience.

    1. Hi BG

      Thanks for your comment. As it goes, I’ve received a few emails following this article, mostly from people who I either know, or suspect, are Jamaican Stone sellers and understandably aren’t very happy with my article. I am still planning to update the article with some of the better and more trustworthy information I’ve received, but just haven’t had the time unfortunately. The main gist seems to be that – as you point out – incorrect use or bad luck causes more problems rather than it being dangerous per se.
      I don’t really want to say you should go ahead and try it, as my personal experience wasn’t that great. But I think if you really want to give it a go, then it’s your responsibility to make sure you follow the instructions carefully, and perhaps start with a very small amount and go from there.
      If you do try it, then it would be great if you came back and let me, and other readers, know how you got on.

      1. Hi Ethan,
        I used black stone few years back and I was very pleased with the result. And recently after read ur article I purchase again. Amazon didn’t deliver to Singapore so I purchase from eBay. Few websites are selling from Malaysia and Indonesia and I am very scared to purchase from them as they famous in sell fake things and cheating. So I purchase from eBay and i am very disapointed. First time I used for 15 mins and it’s didn’t work. 2nd time I apply n wash after 30 mins but result is still same. Big disapointed. I don’t know it’s fake stone or real. Not sure where to get real one .

        1. Hi Shaz,

          Thanks for your comment, and sorry to hear you had a bad experience this time around. I think there are a couple of sellers following this thread, so if they read this maybe they can advise you where to order from to get an original stone sent to Singapore. I will publish the name of a seller if I believe they are legit, but not the link.

  36. Thanks for the detailed review. I’ve been thinking about trying jamaican stone but wasn’t sure. I’m still not sure after reading your article and the other comments lol! but I’m glad to find a good discussion about it anyway.

    1. Hi Ben

      Thanks for the comment, and I’m glad you found the article useful, even if it hasn’t clarified anything for you! But it’s good at any rate to hear different views on something which can be controversial. You’ve also reminded me that I need to look further into Jamaican Stone, so thank to you also:-)

  37. I’ve tried this – the first time I did it wrong, only had it on for five to seven minutes, washed it off and lasted for four hours. And the last time I tried it on I did it correct and didn’t come because of the situation, but my ex loved it – first time I didn’t come with her. Bro it felt amazing to tell her “you sure you can’t take no more?” lol.

    1. Thanks for sharing your experience of Jamaican Stone. I’m glad you’ve obviously found something which works well for you – that’s the most important thing at the end of the day. And I can well imagine how happy you were to be able to ask her that!
