What people say about Arginine and performance
“You could take stuff like arginine and other NO enhancers for a better pump, but I don't think that will make a difference for gains.”
“arginine had on me personally...I'd have the most utterly ridiculous skin-splitting pumps ever...it also vastly improved the quality of my erections...Arginine also stimulated acne production”
“Arginine is great for working out. But arginine also raised my blood pressure and now I know why I got these ugly cold sore blister things.”
“switched it to 3g of citrulline and 6g of arginine that my partner started reacting differently”
