L-Arginine for the cream recipe About helping to slow down or reduce the problem of premature ejaculation. What % is the result of the experiment?

Hello, although there are products on the market that are used L-Arginine to help slow down premature ejaculation. But expect very little results. In general, recommend using Lidocaine in the formula to actually be effective, but Lidocaine for use in medicine only, FDA not for use in cosmetics.
