How can I tell if I have authentic STUD 100® from Canada

To ensure you are receiving authentic STUD 100® that complies with Health Canada’s standards, here is some information you should know to better equip yourself in buying safe, authentic product.

  • BMS Enterprises is the ONLY company authorized to legally import STUD 100® into Canada.

  • STUD 100® has recently upgraded its packaging in Canada. The new packaging consists of a new box that has an additional flap. That product cap, as always, will have the STUD 100® logo embossed on the top. If the product looks different, it is illegal to be sold in Canada. Learn More

How do I use STUD 100®?

Applying STUD 100® is easy – simply spray the head of the penis and wait the recommended timeframe of 15-20 minutes before jumping into action. The wait time is an integral step as you want the penis to absorb the substance and restrict it from transferring over to the user’s partner. The desensitizer is typically available to the male genital area for approximately 2 hours before it dissipates, although desensitizing times may vary for everyone. Each 12g (7/16 fl. oz.) spray can contains enough STUD 100® for approximately 120 sprays.


What's the difference between STUD 100® and Viagra?

Both STUD 100® and Viagra are products that help to enhance your sexual experience, but with a differentiated outcome. While Viagra is a medication that helps you to produce an erection, STUD 100® helps you maintain an erection through delaying ejaculation, ensuring longer-lasting sex. You also do not need a prescription to buy STUD 100®.


Is STUD 100® safe for women?

Absolutely. There have never been reports of any harmful effects on the vulva or the vagina. However, as with ALL delay sprays, you should not use STUD 100® if your partner is pregnant, or if you suspect them to be.


Can STUD 100® be used with condoms?

STUD 100® has been tested with leading brand latex condoms and meets quality control standards with the use of these products.


Is STUD 100® safe to use during oral sex?

Yes, this product is safe to use through all forms of sexual activity involving the penis. It should be noted, however, that it is recommended to wait approximately 15-20 minutes prior to engaging in any sexual acts to prevent the Lidocaine from transferring over to your partner.


Does Health Canada approve the use of STUD 100®?

Yes. Health Canada has a rigorous approval process for general use. BMS Enterprises obtained the rights to be the sole importer of STUD 100® in 1990 and since then, we have taken Health Canada’s standards seriously to provide men with a quality assured product that has been properly tested to deliver a consistent, results-driven experience every time.


Is STUD 100®  animal-cruelty free/ever tested on animals?

Trials of STUD 100® took place on humans only. All the ingredients of STUD 100® are animal free. All the ingredients are either of plant origin or are chemically synthesized.


How long should I wait to engage in sexual activity following application of STUD 100®?

It is best to wait the suggested timeframe of approximately 15-20 minutes before engaging in intercourse or other sexual activity to avoid transfer to the Lidocaine onto one’s partner. Although desensitizing times may vary for everyone, authentic STUD 100® is a powerful and trusted delay spray that typically lasts approximately 2 hours before it starts to dissipate.


Does STUD 100® have any long-term effects?

We are proud to report that many gentlemen have repeatedly purchased this product over the years, and since our inception of selling this product, there has not been any reports pointing to any negative long-term effects on frequent or long-time use of STUD 100®.
