What it is
Stud 100 is a male genital desensitizer spray whose active ingredient is Lidocaine Base USP 9.6% w/w, supplied in a 7/16 fl. oz. can fitted with a child-resistant cap. The carton front carries the STUD 100 wordmark, the product's own statement of identity — "Male Genital Desensitizer Spray" — and the active ingredient declaration, and the reverse of the carton is a full Drug Facts panel. The product facts on this page are transcribed from those printed surfaces.
That distinction matters here. This is an over-the-counter topical product whose carton carries a Drug Facts panel rather than a Supplement Facts panel, so the directions, the ceilings and the warnings set out below are the manufacturer's own printed labeling rather than marketing copy. You can browse the rest of the range in Stud 100 or the wider Sprays category.
What is in it
The panel declares one active ingredient and four inactive ones. The active ingredient is Lidocaine Base USP 9.6% w/w, which the carton puts at approximately 10 mg per spray, and the Purpose column beside it reads Topical Anesthetic. Lidocaine is a local anesthetic that appears in many over-the-counter skin preparations, and "USP" identifies the grade standard the carton is citing.
The four inactive ingredients are printed as fragrance, isopropyl myristate, solvent and stearic acid. The panel assigns no role to any of them, so neither do we — they are reproduced exactly as printed, because an ingredient list is what an allergy check actually needs.

How to use it
The carton sets a floor and two separate ceilings, and those three numbers are the core of its printed Directions. The floor is 3 sprays. The ceiling for a single application is 10 sprays. The ceiling for any 24-hour period is 24 sprays. The Directions place the application on the head and shaft of the penis, before intercourse, or as directed by a doctor, and instruct that the product is washed off afterwards.
Sitting underneath those numbers is a principle the carton states in its own words: correct quantity and time of application are determined by individual requirements, and you should always use the minimum effective quantity. The carton does not hand you a single figure — it gives a range with a hard stop at each end and directs you to stay at the low end of it.
The closure is worth a line of its own. The can is fitted with a Child Resistant Cap, and the carton gives the opening method explicitly: insert a key or a coin and twist it to flip the top open. Store the can below 25°C (77°F).
Who it is for
This is an external-use product for adults 18 and over. The panel sets out two different kinds of restriction, and the difference between them is worth noticing: three circumstances are a flat "do not use" — a local-anesthetic allergy in either partner, broken or inflamed skin, and a pregnant partner — while liver or kidney problems and any current prescribed drugs are instead routed to a doctor or pharmacist for a decision. All five are set out in full in the table above.
The declared quantity is 7/16 fl. oz., which is 0.4375 fl. oz., or roughly 13 mL. That is the only contents figure the carton gives; no spray count for the can appears anywhere on it.
Good to know
The carton's full safety text is in the table above and is worth reading before first use rather than after. Two points there are easy to skim past: the panel says do not inhale, which is a real instruction on something dispensed as a spray and not boilerplate, and it says keep out of reach of children, backed by the child-resistant cap and by a direction to contact a Poison Control Center right away if the product is swallowed.
Two general consumer resources are worth knowing about. The Federal Trade Commission publishes its health products compliance guidance, which is the standard this page is written to. The Food and Drug Administration maintains a consumer page on health fraud scams, which is useful background on how to read product claims in this category. Neither agency endorses, reviews, or has any connection to this listing, and neither page refers to this product.
Frequently Asked Questions
How many sprays does the carton direct?
The carton directs 3 or more sprays, not to exceed 10 in a single application. It sets a separate ceiling of 24 sprays in any 24-hour period, and it states that the correct quantity is determined by individual requirements and that you should always use the minimum effective quantity. Those three figures — 3, 10 and 24 — are printed in the Directions and the "When using this product" sections of the Drug Facts panel.
How long before intercourse should it be applied?
No interval is printed on the carton. The Directions say to apply before intercourse, and offer one alternative in their own words: "or use as directed by a doctor." Because the panel gives no figure, none is given here either, and the carton's own fallback is the one to follow.
Can it be used with condoms?
The carton carries no statement about condom compatibility. Its Drug Facts panel covers the active and inactive ingredients, warnings, directions, storage and the closure, and compatibility with latex or non-latex barriers is not among them. The number printed on the carton for product questions is +1 305 530 8702, Monday to Friday, 9am to 5pm.
What is in it apart from the lidocaine?
Four inactive ingredients are printed: fragrance, isopropyl myristate, solvent and stearic acid. The active ingredient is Lidocaine Base USP 9.6% w/w at approximately 10 mg per spray, with the Purpose given as Topical Anesthetic. The carton also carries an allergy alert directing that the product is not used if you or your partner are allergic or sensitive to local anesthetics.
How is the order packaged?
Orders ship in plain outer packaging with no product imagery and nothing on the outside describing the contents. It will not show the Gear Isle name. The spray itself arrives in its own carton, the one photographed on this page, with the child-resistant cap fitted.
