MuscleTech Platinum BCAA 8:1:1 1000 mg Caplets is a branched chain amino acid formula designed with a potent BCAA ratio of 8:1:1 (leucine, isoleucine, valine). It contains 800 mg of L-leucine, 100 mg of L-isoleucine & L-valine. Unlike other BCAA pills that use ratios like 3:1:2 or 2:1:1, Platinum BCAA 8:1:1 uses an 8:1:1 ratio to load your muscles with leucine with every serving. Research shows that leucine is the BCAA with the highest anabolic potential, as it activates protein synthesis within the muscle through the mTOR pathway. Every serving of platinum BCAA 8:1:1 ensures that your muscles are primed for muscle building.
