Guest guest Posted June 7, 2007 Report Share Posted June 7, 2007 A few days ago, I started taking L-Tyrosine and L-Arginine (500 mg of L- Tyrosine every other morning, 500 mg of L-Arginine every morning. I've since noticed a DEFINITE boost in my libido (which was hovering around zero) and also in the quality of my erections. L-Tyrosine is a chemical precursor to dopamine, so, in theory, taking L-Tyrosine boosts your dopamine levels (or at least increases the amount of dopamine available). L-Arginine is a precursor to nitric oxide, and nitric oxide, in turn, has a role in the physiology of erections, among other roles. Mike (Along with the L-Tyrosine and L-Arginine, I also take Saw Palmetto, Ginkgo Biloba, and Zinc daily, and intermittently use Ginseng, Rhodiola Rosea, and Horny Goat Weed).
