Jamaican Stone is one of the more unusual ways to boost your sexual stamina that I’ve tried.

And not only is it supposed to help men last longer, but it’s often advertised as giving stronger erections too.

As with so many things in life though, the phrase ‘too good to be true’ might have to apply in this case.

It’s now banned by the United States Food and Drug Administration (FDA). This is because someone died from eating it, and the ingredients have been found by researchers to be potentially dangerous.

Having said that, it’s still a popular product in some communities, with many guys saying it works very well – as long as you use it carefully.

So in this Jamaican Stone review, you’ll find all the important information you need to know if you’re thinking about trying it.

What is it?

Jamaican Stone is sold as a natural 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

There have been no official studies or scientific research done on 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? Well, no not really – at least 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 a record in comparison to all other delay products I’ve tried, which wear off in around an hour on average.

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 the taste is strong and unpleasant.
  • 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 US news outlets, such as, 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.

Maybe that explains the burning sensation I experienced.

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 decided to do 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.

So I’d be very cautious about buying it online if I were you.


There are alternatives which don’t present the same problems as Jamaican Stone.

So if you’re interested in trying a desensitizing product, I recommend taking a look at my overview of different desentizing sprays.

    I have a supplier in Jamaican that I can get it from. I am a lady and I didn’t know if it was worth me buying. But, I have found out that a lot of man want it. The friend I have in Jamaican told me to come there and they will take me to someone (a Supplier where I can buy it.) Is there anyone who is still looking to buy this stone? Also, in Jamaican they have a pill that you get from the doctor it lasts for 3 days in your system. and it will make you hard .I know man that have used it and said its great. I have a doctor friend there and he told me man in Jamaican who take blood pressure and diabetes meds have a hard time staying and getting hard. So, the pharmaceutical companies came up with the pill. I can also get them from my doctor friend. What do you guys think about the pill?

    1. Ethan Green

      Hi Patricia,
      I’d be very careful offering to buy it and bring it into other countries! I haven’t personally heard of the pill version. Are you saying it’s a pill version of jamaican stone, or something else?

  2. Hello … many many years ago … maybe 25 yrs My husband returned from the Caribbean with this stone and it does the job. I was just remembering the product and decided to look it up online. Hoping to find a source for this product.

  3. How long does it take for it to work ? Can I use it even tho I’m 1 or 2 hrs from having sex?

    1. Ethan Green

      Yes, you can use it an hour or two, because it lasts for a long time.

    2. yes 1 or 2 hours after applying is even more perfect. it did the job by sending the tingling hot sensation and it should of wear off by 30 or 40 mins but after applying wash it off after 30 mins

    1. Ethan Green

      Hi Rick
      Some sellers claim it might, but it’s not it’s main purpose. Generally products that help with PE by desensitizing aren’t the best if you have erection problems, so I’m skeptical it can help with that.

    2. nope it does not help erectile dysfunction, if they told you yes they lied for marketing. i use it all the time, and it doesnt keep you hard, you will need to purchase something else for getting and staying hard

  4. Steven Craig

    i’ve used this product for a year. it works. i’m mad as hell that the store i bought it from doesn’t sell it anymore. after using china brush for years this product is better. yeah, it stings but you get used to it after you establish your personal dosage. mine stone lasted a year. i preferred to apply mine at least 2 hours b4 sex. for me it gave me the performance i desired. I was able to fuck the shit out of my woman on a consistent basis. it’s even better if you are physically active in other aspects of life also. now that someone provided a supplier i can resume.

    1. I’m in Dallas TX and I need some to buy where am I going to get some to buy please

      Hope can help you and all reader in here.

    1. Ethan Green

      Hi Alfredo
      Their website certainly looks good. But, they use the website Hipay for payments. And that has a rating of 1.6 out of 10 on Trustpilot. So personally, I’ll pass on entering my credit card details to a site that has more red flags than a beach before a hurricane.

      1. Yes Ethan, I’m agree with you. This website like scam website. I’m affraid too entering my credit card. Not Save!!!

  5. Hi Ethan
    Just wanted to ask a stupid question
    After applying Jamaican stone, can one have sex without condom. Like is it ok for the other person (wife / girl friend )

    1. Ethan Green

      Hi there
      That’s actually a very good question. I think it’s fine as long as you make sure you wait a while and wash off any excess before having sex, to make sure there’s no transference to them.

    2. bliingdawg

      Yes you can have sex without condom with wife girlfriend whoever, just afer 30 mins make sure wash it off with soap and water

    1. Ethan Green

      Hi Raj

    1. Ethan Green

      Hi Afshar
      I know, it’s not east to get hold of. I don’t recommend any particular place myself because I don’t want to be responsible for helping people buy a product I see as being dangerous.

  7. My friend told she go down on her man and her lips and tongue got numb do u think it’s the stone he had on

    1. Ethan Green

      Hi crazy
      It’s impossible to say – there are many different numbing products other than jamaican stone. But it could have been a desensitizing product of some kind.

  8. Nathaniel StewaStewart

    I want to order some, please help me try this product out.

    1. Ethan Green

      Hi Nathaniel
      I don’t sell it here, only review it. You’ll have to find an online seller who you think you can trust, or depending on your country you might find a store that has it.

  9. Been using product for years it’s the best last longer than any product in market if get it right can last 45 mins and more resercher must say not good cause making other expensive products look bad for $10 and get 45 min of fun well worth it .

    1. Ethan Green

      Hi Badshah
      Well, I don’t think the Spanish researchers I mentioned had a reason to rubbish it. They would also have fallen into disrepute if they simply lied about the ingredients, so I doubt they made that up.

    1. Ethan Green

      I’m not sure about actual stores, so you might need to look online.

    2. You can visit
      They supply market at Canada and around that.

    3. Hi, if you live at canada. can try buy from
      Good quality.
      Hope this info can help you.

    Bought from the first website suggested before reading the reviews. Ordered to Spain and it arrived within 5 business days.

    First tried it and I applied to much, little bit of a burning sensation which hasn’t gone away yet (applied 1,5h ago) little bit annoying but my own fault. As regards for the stronger erections it’s not the case but I’ve had sex successfully for over 30minutes and not been able to finish which is my intention as I usually last anywhere between 1-3 minutes. I’d rate this as a sucess.

    1. Ethan Green

      Hi John
      Thanks for sharing your experience – I hope that burning sensation disappeared!

  11. Thanks for the advice about ordering it Ethan. I’ve also looked at some sites for delivery and am suspicious of them. Time to look elsewhere I think.

    1. Ethan Green

      Hi Tony
      I just checked that site, and was kind of shocked to see delivery costs that are 4 times the price of the actual product!

      1. Anonymous

        They use EMS 5-8 days, from INA.
        More cheaper than DHL, USPS, etc.

    1. Ethan Green

      Hi Bantu
      I don’t know of any bricks and mortar shops selling it there.

    1. Ethan Green

      Hi ja’red
      You’d need to search for a seller who sends to your country.

        1. Ethan Green

          Hi Larry
          I’m in the UK too, and several companies have emailed me saying I can get it from them. The thing is, I don’t trust the website of any of them. So I’d say don’t bother personally.

  13. everybody

    i’ve been using the Jamaican Stone for a few years and it’s been wonderful. You should only leave the milky cream on your penis for about 15-20min tops then rinse it off good with soap and water. If you wait around an hour before having sex, after rinsing, you’ll last the perfect amount of time (long enough to change positions, confident pumps, and have your mate happy but not too long to never climax). I’ve made the mistake and left it on for over a 1/2 hour before rinsing and that will leave you feeling quite numb and you may take FOREVER to orgasm. Also if you rinse off your penis good and wait around an hour, your mate can give you oral and she/he won’t taste a thing. Hope this helps.

  14. I used the stone, on the recommendation of a Jamaican friend, back in 1994. It worked like a charm, no side-effects. The girl whom I was screwing on the side immensely enjoyed anal sex and so, being 32 at the time, I knew I needed all the help I could get! Long story short, during one encounter, I fucked her in the ass, non-stop, for nearly an hour. I thought my heart would give out before my johnson would! I actually had to take a break and go wash it off in order to finally come. While it never harmed me in any way, I don’t know that it doesn’t possess some potentially harmful side-effects for other guys.

    1. Ethan Green

      Hi Bill
      Thanks for sharing your experience. There’s no denying the evidence that it seems to help some guys, as you so graphically illustrate! It’s just the risks that are the worry.

  15. yEAH J.Stone is good but you have to use it right or you in trouble…

  16. Hello,

    Could anyone suggest if Jamaican Stone is availble to be purchased in Thailand?

    Any advise shall be greatly appreciated.

    1. Ethan Green

      Hi Brian
      I’m not sure myself – perhaps other readers know.

  17. I tried it last week and got that burning feeling too. And I was on fire in bed, but so was my dick so that sucks.

    1. Ethan Green

      Hi Dan
      That’s the thing – it seems to work, but if you feel uncomfortable, it’s not much fun.

  18. Hello, please I used the Jamaican stone as to rub on the tip of the penis, but stay like an hour before washing it off, that was the direction I got from a friend that gave it to me in Paris , so after washing I did good , but refused to wear off , I feel heavy and dead at the tip of my penis. But it works . The only issue now to release me .

    1. Ethan Green

      Hi Joseph
      It sounds like maybe you just used too much and didn’t wash it off in time. Hopefully your penis will recover fully from the numbing.

  19. Glorybwoy

    Hmmmmm.I was once told by a friends that I can prevent ur penis from erecting when it been used too much meaning u will bee impotent

    1. Ethan Green

      I know Jamaican Stone can cause some problems, but I don’t think it can cause impotence.

  20. Thanks for the useful review and the site. one of the best I’ve seen about pe.

    1. Ethan Green

      Hi Jim
      You’re welcome! And thank you too for the compliment!
