I don't know, the only way to know would be to go back in time and not take all that C, and then compare myself to meself. I don't have any wrinkles though, my skin is tight, an I feel like a 19 year old. I rode all the roller coasters at Geauga Lake in Aurora Ohio last week and my younger relatives thought I was a nut. Feel sorry for them a bit, they need to get their money's worth out of the admission fee more next time. Never had any performance problems and still wake up with a boner every day - Hah ! I'll take C as long as it's available.
