Spent about a year testing various topical products including VigRX Oil, Prosolution Gel, various alprostadil creams, and some peptide-based topicals. Here's what I found. Vasodilating topicals — particularly those with alprostadil or nitroglycerin — produce a real, fast, temporary engorgement effect. This is the same mechanism as the pills but more direct and faster acting. Erection quality and temporary fullness improve noticeably within minutes. Duration 1-2 hours. Herbal blend creams — mostly nothing. The absorption through skin is limited and the active concentrations are too low. Collagen-stimulating peptide topicals — more interesting and I'll post separately about those.
