Positive experiences

Negative and mixed experiences
“I worked out for 6 days straight...took my Arginine & Citrulline...reactivated my shingles (which are painful AF)”
“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.”
“I've tried L-theanine, magnesium glycinate, turmeric, arginine...which have provided no results or transient results”
“I've been taking arginine, citrulline, and glutamine for that with so so results”
“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”
