Dymatize BCAA Complex 2200 provides 2,200mg of pure free form Branched Chain Amino Acids (BCAA's) per serving. These amino acids, their most easily assimilated form, are essential for maximum muscle regeneration. They also play a key role in normalizing moods, concentration, aggression, attention, sleep, and sex drive. Not only did Dymatize combine these highly efficient amino acids with nutritional cofactors, but we also made it time-release for added effectiveness.
