Stud 5000 Review: A Delay Spray That Failed To Impress

Stud 5000 is a lidocaine-based delay spray intended to help men last longer during sex by reducing the physical sensitivity of the penis.

I found it has a strong numbing action, works very quickly and lasts a long time. However, it does have a slight chemical smell and doesn’t seem to be the best for oral sex.

It isn’t made by an established company, so this is one for men who just want a cheap generic lidocaine spray.

Please note that I don’t include links to buy it in this review because of the lack of key information I’d like to see before recommending a product.

Who makes it?

There’s no connection between Stud 5000 and the classic spray Stud 100. Despite the similar name, it’s not a new version of Stud 100 and is made by a different company.

Just as I discovered when writing about Climax spray recently, the manufacturer appears to be a pharmaceutical company in India – Universal Life Science.

They don’t appear to have a website though, and I can only find a brief description of the company on a couple of Indian wholesaler websites, such as

And strangely for a pharmaceutical company, the email address on the spray’s packaging doesn’t sound particularly professional:


Stud 5000 contains the most common ingredient of delay sprays – 10% Lidocaine topical anesthetic.

There are no other listed ingredients apart from ‘solvents, excipients & propellants’.

How to use Stud 5000

There’s no instruction leaflet included in the box, so the only instructions are printed on the side of the box and the spray bottle:

Shake well before use…For external use only…Hold the container 10 cm. apart with the arrow on the spray button pointing toward the area of application. Press button repeatedly to spray…Do not use more than five sprays of one second duration each time.

There’s nothing about where to spray exactly, how long to wait, if you should wash it off and if you can use it with oral sex or a condom etc.

These are important points, so it’s a shame they didn’t include them in the instructions. So if you’re planning on using it, you might like to read my advice about using delay sprays.

Here’s how I recommend using the spray

  • Make a test spray on the arm to test the skin reaction. Wait 10 mins.
  • Spray just once onto the penis head and rub it in.
  • Wash your hands.
  • Wait 5-10 mins, then wash your penis with warm water.
  • Turn on the music and have fun with your partner.
  • Decide if you need more than one spray in the future.
  • Don’t use it with oral sex (more on that below).

My experience

As always, I tested it on my arm to check how my skin would react. That was fine, but I immediately noticed two things: it has quite a strong smell, and it sprays in a continuous flow, with no metered pump.

Right from the outset both of those points were a disappointment. I think it’s much better to have a metered pump so you can apply roughly the same amount each time. And nobody wants a strong chemical spray on their penis when they’re in bed…

I waited 10 minutes, then had a quick shower to get rid of the smell and any residue. I know from experience that once they start working, you can have a hot shower and wash thoroughly, and the effect will still be there.


I did notice a slight tingling sensation, which is typical of lidocaine sprays. But it was light enough not to cause any concern.

I then called my partner into the bedroom for some testing. She’s used to testing these sprays with me now, so even with music and candles, we still have a laugh about it!

We started with some foreplay, and I was noticeably numb. Not as numb as some sprays make me, but numb enough to know it was working well.

My partner gave me some oral, saying there was still a very faint lingering taste and smell. She described it as almost mint or eucalyptus, but I couldn’t smell that.

Numb mouth!

Five minutes later and she suddenly announced that she could feel her mouth a bit numb. She asked me if I’d washed properly (thanks!) to which I replied I had, of course.

So this was an unexpected issue that we haven’t seen for some time. For whatever reason, it seems the spray wasn’t being absorbed properly by my skin.

She put that aside though, saying it wasn’t too dramatic, and we moved on to some sex. The spray did a good job of keeping the sensitivity down, and as expected, I lasted a little longer than I would do without a spray.

There was definitely some loss of pleasure, as usual with these sprays. But having only sprayed it on my penis head, I still had full sensation on the shaft.

All in all, the effect lasted for around 2 hours before wearing off slowly.


  • Numbs well, helping you last longer by reducing penis sensitivity.
  • Takes action quickly – just 5 to 10 mins before sex is enough.
  • Only a light tingling sensation – nothing too strong.
  • Lasts a long time – 2 hours or more.
  • Low price.


  • No metered pump, so it’s hard to get the right amount.
  • Has a strong smell and taste unless you wash very thoroughly.
  • Doesn’t seem to be good for oral sex.
  • No information about the company that makes it.
  • Lack of instructions or safety information.


Stud 5000 appears to be a very basic, generic desensitizing spray. It does provide fast and strong numbing, that much is for sure. But the manufacturer doesn’t appear to have done much more than add some lidocaine to a spray mix, and give it a name that sounds like an already established brand.

My partner and I were both unimpressed with the strong smell and taste. And we were surprised to find it numbed her mouth during oral, even after I’d washed off any residue.


  1. Hi. I have used viagra and stud 100 and both of them worked fine together.
    Wife same to enjoy the sex, best sex in 10 yrs we have ever had.

    • Thanks for sharing that Davie. I’ve also tried viagra with a spray before and had no problems.

    • Personally I wouldn’t have a problem using a condom if I wanted to. Some sprays say you can’t, but if it doesn’t state it on the instructions, I would probably do it.

  2. Hi Ethan,
    Thank you for this great review. It helped.
    My doubt is that, can I use it regularly? Is there any known side effects for these sprays on long term usage?

    • You’re welcome Tony! Normally it’s ok to use them daily. But some advise not to use more than a certain number of sprays in 24 hours. Some don’t say anything at all! I personally don’t use them more than once per day.

  3. My problem is that I can’t last long even some time with a small sensation, I ejaculate.
    I used a massage oil which helped me to get a strong and near to rock hard erection, but due to my pre-ejaculation I fail to hold that erection.
    Even when I don’t ejaculate and stop doing sex for half a minute I lose my erection.
    Will any spray will work in my case? If so, then please suggest me a good one which is not harmful for the erection.

    • Hi Lims
      I think if you have erection problems, sprays can be difficult to use because they work by making you numb. So if you have both erection problems and premature ejaculation, it’s important not to use a treatment which makes the other problem even worse. For me, when I had problems with both ED and PE, viagra and other products like that seemed to help me the most. But that’s not exactly a cure either, and has its own risks. I would perhaps try experimenting with a spray but only a very small ammount, and see if that helps. And only apply it to the penis head, and not all of it. If you are okay practicing on your own, you can experiment and see what works best for you.
      As for which one, many of them are very similar really. Take a look at my main sprays page for more info.

    • Hi Lims
      Difficult question to answer really. I think it’s not so easy to say that one spray helps last longer than any other as the ingredient tends to be similar and different people react in different ways. So I would just try my main recommendations on my main delay spray page.

  4. Have to disagree with some aspects of your review.
    Because it’s aerosol, you spray longer, (at least 1 full second – which is longer than most people think) and it’s easier to get a measured dose. I find the pump sprays sometimes don’t give a full measure, and the spray is very narrow.

    This does seem to work faster, but in my experience it seems to wear off more quickly too.

    I’ve found most of the lidocaine spays to be similar. If you want to reduce the initial tingling when sprayed on, try warming the bottle up first. It’s most likely the suspension agent evaporating off your skin.

    I’ve never had any chemical odours, etc problems or complaints – but I give my knob a good wash with soap and water before oral, so maybe that’s the difference.

    Benzocaine based sprays don’t seem to work as well for me, but I don’t have a “consistent test platform”, if you know what I mean…

    There are a couple of other products you might want to look at.
    Dynamo Delay, another lidocaine spray, but with 13% and Adam & Eve with benzocaine.

    I should note I used Stud 100 first, so I am speaking relative to that product.
    Of the 3 I have used, Dynamo required less sprays due to it’s greater lidocaine content, Stud 5000 as above.
    I also found rubbing them in seemed to lessen their effect in my case.

    It’s a matter of experimentation and common sense for each user.

    • Hi there
      Thanks for adding your view and some food for thought. You’re welcome to disagree with my review, and I welcome other opinions. Having said that, I don’t think you’re right about the aerosol being easier to measure than a metered pump. I’ve tested many different sprays, and the metered pumps always win in terms of getting a similar amount each time as far I can tell.
      I haven’t heard your theory about the suspension agent evaporating off the skin, or warming it up before. As far as I’m aware, the uncomfortable feeling is a reaction to the lidocaine or benzocaine usually.
      I do agree that it’s a matter of experimentation and common sense though. You need to use them carefully, and work out what’s the best system of using it for you personally.

  5. Hi Ethan: Thanks for an interesting article on STUD5000 spray.
    A couple of issues I don’t agree with you.
    Why not do oral before proper sex (using spay) as even an illiterate person knows that these sprays are a kind of chemicals.
    Apologies for lack of instructions.
    Please advise me to what instructions you would like with the can so that I can advise the manufacturer.

    • Hi VK
      Could you explain your connection with the spray and manufacturer please?
      But to briefly answer your question, a leaflet explaining all the information about the spray would be a good start. If you buy one that’s recognized by medical professionals, like promescent or fortacin, you’ll see what I mean.

  6. Thanks for the useful review. I thought this was the latest Stud 100 version, so i’m glad I found this article. Amazing that they used the same name…

    • Hi Tom
      You’re welcome – I’m happy to hear the article was useful. Yes, it’s a bit of an issue with delay sprays and other male enhancement problems these days. With the lack of regulation, there are a lot of rip-offs popping up all the time.

      • Hi Ethan,

        Two things that I need to know.

        1. If I will use it 10 mins before sex when erection is not there, will I face any issue in erection which I usually don’t have?

        2. can you please tell the exact area where it has to be applied based on your good experience?

        • Hi Rahul

          1. Some men have problems getting an erection because of the numbing. Others are fine. You’ll have to find out through testing.
          2. The penis head, ideally with the foreskin pulled back. But some men also apply it to the rest of the penis if they find it helps better.
