Stud 100 Review

stud 100 spray


Of the many delay sprays I’ve tried, Stud 100 had one of the strongest effects, helping me delay ejaculation for several minutes.  You can use it for sex and oral, with or without a condom.

As is always the case, you need to make sure not to apply too much, or it can affect erection quality. But when you work out how much to use, it’s an effective numbing spray.

My experience

I was pleased to discover that the bottle has a metered pump so you can apply a similar amount each time. Not all sprays (and gels of course) have this useful feature to help you get the dosage right.

I sprayed the head of my penis once and gently rubbed it in, paying attention to the tip and frenulum which is where I’m most sensitive. I waited for 10 minutes, then wiped myself with a damp cloth to remove any residue.

I could definitely feel a good amount of numbing even before the 10 minutes was up. And really, it seemed similar to most other strong lidocaine sprays I’ve used.

Helped me last a few minutes longer

It worked well that first time around, helping me last several minutes longer. In one session later that week, I was able to last more than 10 minutes – which was a considerable improvement to my usual 2 to 5 minutes.

I was still able to feel pleasure, which is of course very important! However, as usual, the sensation was considerably dulled on the penis head with the numbing.

But there’s always a trade-off between pleasure reduction and longer sex with these sprays, so on the whole I was happy enough with Stud 100.

3 sprays is too much

I also experimented with 2 or 3 sprays. 2 was ok, but perhaps a little too strong. And 3 was total overkill, making it difficult to get an erection – especially when I rubbed it into the shaft as well.

So for me, 1 is definitely the magic number. This does vary from person to person, of course, so you might find you need 3 or more even.

Fine for oral and condoms

Stud 100 does have a light smell, which all lidocaine sprays do. It wasn’t too bad though, and with a shower rather than a wipe, the smell pretty much disappeared, whilst the numbing remained.

It was ok for oral if I wiped the excess and waited for it to absorb – my partner had no complaints about the smell, taste or numbing in her mouth.

And you can use it with or without a latex condom, which is always a plus from this type of spray.

Tingling sensation

All lidocaine sprays give me a bit of a tingling sensation, and some of them an intense ‘get this the hell off’ burning sensation.

Fortunately, Stud 100 was at the light tingling end of the spectrum, so was tolerable.

Who makes it?

Stud 100 is manufactured in the U.K. by Pound International. They’ve been making and selling it since the 1970s, making it the oldest desensitizing spray I’ve seen.

Stud 100 Ingredients

  • Lidocaine Base USP 9.6% (the active ingredient)
  • Isopropyl Myristate
  • Stearic Acid,
  • 2-(2-Ethoxyethoxy) ethanol
  • Fragrance

Is it safe?

The manufacturer states that Stud 100 is FDA compliant, meaning they adhered to the standards set for male desensitizing sprays.

The manufacturer also says it’s safe for use during oral sex. But be sure to wait at least 10-15 minutes after application to avoid the risk of numbing your partner’s mouth.

Lidocaine can on rare occasions cause problems for some people. Stud 100 is unlikely to cause any problems at such small doses, but be careful not to use too much of it in one session.

If your partner is pregnant, it’s best not to use this, or any other desensitizing spray.


  • It works quickly – 5 to 15 mins before sex
  • Has a strong numbing effect
  • The metered pump means it’s easier to apply the same amount each time
  • Fine for oral sex
  • It can be used with or without a condom
  • Only a light smell
  • You don’t need a prescription
  • It’s FDA compliant.
  • It’s low cost and you get plenty of sprays from one bottle


  • It can take a few experimental sessions to work out the number of sprays you need
  • It can reduce some of your pleasure
  • Can produce a tingling sensation you have to put up with (as with most lidocaine sprays)
  • If you apply too much, the strong numbing can make it difficult to maintain an erection
  • It’s not a cure, so you’ll have to use it every time you have sex


Stud 100 worked for me in a similar fashion to the other good delay sprays that use lidocaine as the active ingredient. So like Promescent, Dynamo, and K-Y, I think it’s one to try if you need to reduce your sensitivity.

It’s good that it has the metered pump, can be used for oral and with or without a condom. These are some of the basic usability points I look out for.

And unlike some of the less impressive sprays out there, it absorbs quite well and doesn’t have too much of a chemical smell, so you can use it fairly discreetly before you have sex.

One final point in its favor is that it’s not as expensive as some of my other top rated sprays. So if you’d like to test a decent spray without spending too much money, this is a good bet.

  1. Hi my penis is very sensitive, so sensitive I cant receive a blow job. Wondering if the numbing will allow that now?

    1. Ethan Green

      Ideally, yes. But since different men react differently, and to different sprays, it’s kind of hard to predict whether you will be able to do exactly what you want. Hopefully, it will work for you, but you’ll just have to try it really.

  2. I just wanted to know if we put 4 doses of spray, how much time we will I get?

    1. Ethan Green

      Hi siby
      It’s impossible to judge. But increasing the number of doses doesn’t automatically mean you will get even more time. It’s all about finding the right balance between numbnig you enough to last longer, but not so much that you can’t maintain an erection or enjoy sex.

      1. Ethan Green

        Either is fine, but flaccid might be easier if you need to wait for it to work. But if you find it makes it difficult to get an erection afterwards, try putting it on the erect penis instead.

  3. Hi there,

    My partner and I are trying for kids and I use the Stud 100 regularly & has worked very well for me but just wanting to ask if the Stud 100 spray affects my partner falling pregnant or is it only an issue when she is pregnant??

    1. Ethan Green

      Hi Benji
      They normally say not to use these sprays when trying for a baby or when pregnant. So for now, I would avoid it.

  4. When applying stud 100, is unprotected sex dangerous? or do you still feel that urge when cumming? and does it give you time to take your penis out of the vagina?

    1. Ethan Green

      Hi Karl
      I don’t think it’s dangerous as long as you make sure there is no residue so you don’t numb your partner. Yes you can still feel the urge. And you should have time, but that depends on you I guess, as different people have different levels of awareness about when it’s approaching.

      1. How long does the numbing effect last for.. so can I put it on then have sex 3 hours later and still be fine?

        1. Ethan Green

          It might still work a bit, but you’d need to experiment. For me, two hours is the time it starts to reduce in effect.

  5. Sir after applying stud 100, after 10 min before sex I should wipe with a cloth, or else I should make that cloth into wet and wipe, like should wipe with a little water?

    1. Ethan Green

      Hi Stelin
      It’s up to you. Either should be fine. Personally, if I’m having unprotected sex, I use some water just to make sure it doesn’t transfer and numb my partner.

  6. Hi,
    I used it before, I tried with 1 spray in the soft area not in the head, I used it for only oral and that time I didn’t get good feel like normal but it was delayed and kept me on more time, so my question is,
    1. It can be spray only on the skinless head instead the whole penis?
    2. After 15 minutes and wiped out, I can go for direct intercourse without latex? – Means it is safe to my partner?
    3. While using without latex, Is it safe to a woman approaching pregnancy?

    1. Ethan Green

      Hi Vijay
      1. It’s your choice. It’s fine to experiment and see what works best.
      2. Yes that’s fine.
      3. Usually they say no.

      1. Billy Narcisse

        Seems like I didn’t use stud 100 correctly. I think I put a lot of spray in a session so it’s difficult for me to get an erection. What should I do please?

  7. I am awaiting my stud 100 supply. It may arrive tomorrow. My question:

    If I have sprayed stud 100 on my penis and suddenly sex is called off for the night due to unforeseen circumstances, is there a problem?

    1. Ethan Green

      Hi Amoz
      I hope the spray works well for you (and that sex is not called off!).
      There is no problem regarding the spray. You will probably feel numb down there, but it should go away naturally without any issues.

    2. I received my supply of Stud 100 on 16 February 2019. The first time I used it I sprayed twice, I have no problem to get a hard erection and I did not feel any tingling sensation or numbness even after 30 minutes but the sex was just about 5 minutes. At 1.30 am I was awakened by the tingling sensation but managed to sleep back.

      The second time I sprayed three times and I had a hard time to get an erection and when I finally got the erection, it was not so hard and sex lasted just about 5 minutes. There is no tingling sensation or numbness.

      In view of the unfavorable experience of not getting an erection instantly as it used to be, I stopped using stud 100 just after two times. I was dead worried that I might not get an erection at all.

      I don’t drink or smoke and I really take care of my diet. Along the way, I read one’s man comment that he can only last long in bed if he was drunk. I search online about the type of wine that increases sex drive. I found out that Red Wine was great for sex. I purchased a bottle of red wine with 14% alcohol contents and I drank about 50 ml only just before I had sex with my wife. Interestingly, I lasted about 40 minutes in bed with steel hard erection for the very first time since so many years. Since then my sex life is now on cloud nine and every morning I got morning wood which was rare in the past.

      For me, Red Wine is the answer to my acute premature ejaculation problem. I drank red wine for sex and it works fantastic for me.

      1. Ethan Green

        Hi Amoz
        Thank you for sharing your experience. First of all, sorry to hear the spray wasn’t right for you. Secondly, I’ve also found alcohol in the right amount can be very effective for PE. Too much and erection problems can happen again, but just the right amount seems to help a lot.

      1. Hi, I used this stud 100 spray a couple of times, and once I felt like dizzy and a bit of a headache at the same time. I might have sprayed a bit too much. Suggestions please!

        1. Ethan Green

          Sound to me like you already know what to do – spray less! One technique to apply only a tiny amount is to spray it into your hand, or even a glass, first. then dip your finger in and just apply the amount to your penis that sticks to your finger, and wash the rest off.

  8. Hi Ethan,

    Thank you for this review. I have just ordered from boots and awaiting arrival. I am not circumcised and plan on applying 1-2 sprays before I become erect therefore pulling the foreskin back can be somewhat painful, even when erect. I usually just let it naturally come back during sex. Would it still be effective if just sprayed on the external head whilst my foreskin is covering?


    1. Ethan Green

      Hi Simon
      You are very welcome! I hope it works out well for you. It shouldn’t be painful to retract your foreskin. Have you spoken to a doctor about that? Perhaps you could have a shower to loosen it up and then apply the spray to the head when you’re out. It might help a little to spray on the external head that you can see, but ideally, it’s good to get the whole head and especially the frenulum sprayed.

  9. Hi Ethan,

    Thanks for the post. I have a question

    when should this be applied? Can this be applied before the fore play when one is not that erect? And still get an erection normally one gets during the fore play?

    1. Hi Aman
      You’re very welcome! Yes, you can apply it before you even start foreplay if you like. It should last for at least an hour. You can get an erection as long as you don’t apply too much of it. Some men have no problem getting an erection with a delay spray, others find it a problem. So my advice is to experiment with just a small amount on the penis head to start with.

    1. Hi Gordon
      It depends on how much you put on etc. But in my experience, this and other lidocaine sprays usually last a couple of hours.

  10. Which is better sir? Spraying on the head and shaft of the penis or just the head

    1. Hi Seni
      In my experience just the head. If you spray the entire penis, the risk is you’ll feel no pleasure. You can experiment if you like, but I think it’s good to numb the head and keep full sensitivity for the shaft. But if that’s not enough for you, and you’re still too sensitive when you have sex, you might like to spray the entire penis to see if that works out better.

  11. Is there any serious side-effects after applying the stud 100, and in period of waiting for the spray to absorb….then something happens like emergency call or any other thing interrupting that moment, then my partner is no longer in the mood for sex, what should be done in that case?

    1. Hi Ali
      Most men have no problems. Very rarely there might be a reaction to the lidocaine ingredient, like serious burning sensation or a rash.
      If you are interrupted it’s no problem. You can carry on your normal day, just with a numb penis in your pants!

  12. Hello Ethan,
    I want to know if after I sprayed the stuff and waited 15 minutes before sex, should I wash the penis or wipe it with a wet towel or not?
    Minimum 3 sprays before sex?
    How much time can I have sex after using spray?
    Drinking alcohol before or after using spray, and during sex, can affect me in some way?

    1. Hi N
      1. Wash or wipe is fine.
      2. I would use 1 spray to start, add more next time if needed.
      3. I thnk 10-15 mins.
      4. Alcohol should be fine.

  13. It’s not a cure, so you’ll have to use it every time you have sex. What does that mean? does it mean that if I used it one time I have to keep using it every time I wanna have sex?

    1. Hi Mo
      It just means it only works when you use it. You can’t spray once and then never have premature ejaculation again. But it doesn’t mean you must use it forever just because you used it once either. It’s a choice.

  14. Medeiros

    Devo aplicar o stud 100 entre 5 a 10 minutos antes de ter relações com o pênis eréctil ou flácido.

  15. Hi, if I go out, can I apply stud 100 like 2 hours before sex? don’t want to apply it on when the other person is there.

    1. Hi Alex
      Great question! This idea is something I might write about soon – how to use products like these in as subtle a way as possible.
      I think the key is to experiment yourself at home first. Apply the spray, and time how long your penis stays numb for. Get a sex toy or just masturbate normally to see if the effect is still good after 1, 2, 3 or more hours. Then you can work out how long your window is between going out and having sex.
      Otherwise, just pop into the toilet before sex and spray it subtly.
