Stud 100 Review

stud 100 spray

Stud 100 is a desensitizing spray which can help you last longer during sex by reducing the level of physical sensitivity you feel.

Among the many delay sprays I’ve tried, it had one of the strongest effects. In this review, I’ll explain how well it worked for my partner and I, tips for using it correctly, and a look at some issues to bear in mind.

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.

They have a dedicated website, where they describe themselves as a “family-owned pharmaceutical group”.

Stud 100 Ingredients

Active ingredient:

  • Lidocaine Base USP 9.6%

Other ingredients:

  • Isopropyl Myristate
  • Stearic Acid,
  • 2-(2-Ethoxyethoxy) ethanol
  • Fragrance

My experience


First tests

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 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.

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.

Pros

  • 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

Cons

  • 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

Verdict

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.

Where to buy

If you’re based in the U.S, you can usually find it for around $10-12 on Amazon. There are also plenty of customer reviews to read.

In the U.K., you can buy it from most of the usual online pharmacies, including Boots now. At the time of writing, Boots have it online for £5.99.

Alternatives

There are lots of different sprays, so you might like to read my review of delay sprays.

      Hi Sarath
      Yes, as long as you wipe/wash first to remove any of the product after it has been absorbed.

      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.

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

    1. Ethan Green

      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.

  2. 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. Ethan Green

      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!

  3. 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. Ethan Green

      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.
      Ethan

  4. 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. Ethan Green

      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.

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

    1. Ethan Green

      Não importa se é ereto ou flácido – você pode decidir com base no que funciona melhor para você.

  6. 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. Ethan Green

      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.

    Hi there
    I used stud 100 twice in a week last month when I was on vacation. The first attempt it worked superb. after one day when I apply it for more fun with my partner between intercourse the penis got down and lose the strength and power and it’s been 4 months I m waiting for miracles to happen so that my penis came into same strength and power the way it was before… is this side effect
    I mean the timing was okay but it wasn’t standing properly

    1. Ethan Green

      Hi
      Do you mean you haven’t been able to get an erection for 4 months since using the spray? I don’t think that could be related to the spray, and there is probably something else causing it. I would speak to your doctor about this to check there isn’t a physical cause of your sudden erectile dysfunction.
      Sorry to hear you’ve had this worrying experience, and I hope you find a solution.

      Hi Dave
      As far as I know you can combine the two. If anything, the viagra might help overcome the problem delay sprays sometimes have with erection loss due to the numbing. If that’s an issue, I would use less spray if combining it with viagra.

    Hie
    Is it good for maintaining erection of the penis or it’s just for the lasting?
    And is it available at any local pharmacy?

    1. Ethan Green

      Hi Rahul
      It’s only to help with lasting time. I don’t know any pharmacy that sells it – just online.
      Ethan

  9. If u have a problem maintaining an erection can u try it or no?

    1. Ethan Green

      Hi Ryan
      I think there’s a chance you’ll struggle with it. But since it’s relatively inexpensive, you might like to try it a couple of times and see. I guess it depends what causes your erection problems and if reducing sensitivity will be the final nail in the coffin or not.
      Ethan

  10. Sir can I use it without a condom? If i have sex without condom, does it cause problem for women? What spray won’t make problems?

    1. Ethan Green

      Hi Aayan
      Yes you can use it without a condom. Just make sure you wash or wipe your penis first.
      Ethan

  11. 1min man

    If I wash it off after about 10 mins, won’t I be washing away the spray?? Can I use it without washing it off?

    1. Ethan Green

      Hi
      No, the spray will have taken action by then, and you can’t wash it off once it affects the nerve endings under the skin. You can use it without washing it off, but only with a condom. And it’s better to at least give it a quick wipe with a cloth.
      Ethan

  12. Hi,
    I want to receive oral (foreplay) before intercourse, but I don’t want my gf’s mouth to get numb. After 10 min of spraying it on, if I wash it thoroughly with soap and warm water to get rid of the odor/taste so that it’s safe for my gf to give me oral, would it still be effective?

    1. Ethan Green

      Hi Don
      Yes, it will still be effective. I’ve experimented with waiting that long and having a long hot shower with soap, and it still works fine. Once these sprays are absorbed into the skin, they stay working until they wear off, not when you wash them off. So there’s no problem there.
      Ethan

  13. Hi I have this problem whenever I go to massage parlour and during the foreplay my penis is not half erect and I ejaculate. will stud 100 help me with full erect ejaculation also should I apply it when my penis is flacid?

    1. Ethan Green

      Hi Is
      I don’t think it’s going to help in this situation. My thought is that it’s probably more psychological. You could try it though if you want to, but you might find it makes it even more difficult for you to get a full erection because of the numbing. It can be applied either flaccid or erect, but if you have erection problems, it might be better to wait until you’re erect.
      Ethan

  14. Hi..after spraying snd waitin 10 to 15 min should i wash it with warm water only or i should use shampoo as well? And spray only the top not the whole penis?

    1. Ethan Green

      Hi Ash
      Just warm water will work fine. I wouldn’t use shampoo, but maybe a mild soap if you want to get rid of any smell or taste. And yes, usually it’s just the top of the penis you spray.
      Ethan

  15. Hi sir, plzzz tell me that how many times we can use this in one month?? Or in one week??

    1. Ethan Green

      Hi there
      I don’t know what the manufacturer recommends, but most of these sprays are usually ok if you use them once a day.
