I'm reviving this topic because I've been taking Arginmax for about 8 months and it does seem to help increase response. The main ingredient is about 2500 mg l-arginine (amino acid). I've researched everything I can and there doesn't seem to be any side effects from l-arginine but I'd like to see if anyone else has taken Arginmax and had long-term side effects or knows anything else about this.BTW, it's way cheaper to buy on drugstore.com than at the local health food store.Thanks to any and all ladies who respond. You all have helped me so much.
