4/5
PurplEwrAAth contains not just the three major amino acids, the BCAA's, but also L-Lysine (necessary for building protien in the body), L-Arginine (reduces healing time & repair of damaged tissue), L-Histidine (importants for infants, but also thought to be benificial in adults), L-Histidine, L-Theronine (aids in fat metabolism in the liver & helps the body absorb nurtients), L-Methionine (essential for the production of creatine) & L-Phenylalanine
PurplEwrAAth also contains some added bonuses like Niacin (Vitamin B3), Vitamin B6, Beta-Alanine (known to improve athletic preformance & build lean muscle) & Citrulline Malate (aids in aerobic preformance by reduing fatigue & influencing latic acid metabolism).
I have to recommend the Purple Lemonade flavor. It's kind of an odd flavor, but much more desirable then grape. The grape flavor tasted like an old grape tootsie roll pop
