I had read somewhere that L-arginine and L-lysine were both good for sexual health, so I bought them both. Then I read on here that you shouldn’t take them at the same time because they compete for uptake or something. Does this mean I can take them both on the same day, just not in the same hour? Or is taking L-lysine on the same day as arginine pointless? What exactly are their respective benefits? I know arginine is supposed to increase semen quantity, how about lysine? Does that help erection quality? It would seem like that would be most important for PE, though the increased ejaculate is nice. Yet arginine seems to be most popular.

I know I’ll probably be told to use the search feature, but almost everything seems to be about arginine. Anyone mind helping me out here? :)
