Stud 100 Delay Spray vs. Promescent

Although the ingredients in Promescent and Stud 100 may look very similar, these two medications were not created equally. Let's start with the active ingredient in both medications which is lidocaine. Lidocaine is a topical anesthetic that can be sprayed "on demand" to reduce sensitivity of the penis allowing men to delay ejaculation. Although useful in delaying ejaculation, lidocaine can also dramatically reduce your penis sensitivity and sexual pleasure unless it's formulated with absorption technology.

Absorption Technology - Key for an Effective Delay Spray

Stud 100 uses Un-ionized lidocaine which has limited transdermal absorption. This means that after applying Stud 100 to the penis only a limited amount of the medication is actually able to absorb below the skin. This is due to the fact Un-ionized lidocaine has a limited capacity to penetrate through the top layer of the skin (the stratum corneum) into the dermis. The dermis is the most important layer of the skin for the medication to actually reach because it contains the nerve endings that control ejaculation.

Unlike Stud 100, Promescent absorbs through the stratum corneum and into the dermis because it contains Ionized lidocaine. This allows the medication to actually reach the nerves responsible for ejaculation and at the same time allows for greater sensation on the top layer of the skin. This is because the lidocaine was actually able to absorb below the skin and is not stuck on the surface.

Avoid Transference to Your Partner

Unless a condom is used, Stud 100 will transfer to a partner due to its limited absorption capability. To minimize the amount of transference, Stud 100 users would have to apply the medication 30-60 minutes prior to intercourse. Promescent will not transfer to a partner and only needs 10 minutes for the medication to absorb below the skin.

Users of Promescent do not have to worry about transference which gives it a huge advantage over Stud 100. Lidocaine transference can cause vaginal numbness to the female partner which will greatly reduce or may even eliminate her ability to achieve an orgasm.

In conclusion, Promescent is the better treatment option for PE due to two advantages. Its formulation of lidocaine allows for enhanced absorption so it can work more effectively and there is no issue of transference to ones partner.
