Different Active Ingredients
Trojan uses benzocaine and Dynamo uses lidocaine.1,2 Both are local anesthetics that temporarily reduce sensitivity. Guideline and review evidence supports topical anesthetics as a class for premature ejaculation, mostly from studies of lidocaine-based products.3,4 We haven't found a head-to-head trial of these two products, so we don't claim one works better. For a benzocaine option from Dynamo, see benzocaine wipes for premature ejaculation and delay spray vs. delay wipes.
How Trojan Delay Spray Is Used
Dynamo's label lists about 10 mg of lidocaine per spray and directs 3 or more sprays, not to exceed 10, to the head and shaft before intercourse.1 Trojan's label says to apply "a small amount" and let it dry, not more than four times a day, only on intact, non-inflamed skin.2 Follow the label on the package you buy.
Condoms and Oral Contact
Trojan's label says it's compatible with latex condoms and "not suitable for oral use."2 Dynamo's label makes no condom statement.1 Whichever you use, let it absorb and wash off any product before oral contact, and ask a pharmacist if you're unsure about condoms.
Which One Fits You?
- Trojan may suit you if you need a product labeled as latex-condom compatible, or you'd like to try benzocaine instead of lidocaine.
- Dynamo Delay Spray may suit you if you want a lidocaine spray with a stated amount per spray and no fragrance listed on its label.
- Allergies: if you're allergic to one "-caine" anesthetic, ask a pharmacist before trying another.
Safety and When to See a Doctor
Don't use any lidocaine or benzocaine product if you or your partner are allergic to it, or on broken or inflamed skin. Avoid the eyes. Wash the product off after sex. Using too much can cause too much numbness; use the least that works. Stop and ask a doctor if you or your partner develop a rash, burning or itching.
Talk to a doctor if you usually ejaculate within about a minute and it bothers you, if the problem started suddenly, if you also have erection problems, or if a spray used as directed doesn't help. The International Society for Sexual Medicine's guidelines cover the options.3 See also how to stop premature ejaculation.
The Bottom Line
Trojan Extended Pleasure is a benzocaine 7.5% spray labeled compatible with latex condoms and not for oral use. Dynamo Delay is a lidocaine spray at about 10 mg per spray, with 3 or more sprays not to exceed 10. Pick based on the active ingredient and label notes that matter to you, and follow the label you buy.
