The Primary Building Blocks for Muscle Branched chain amino acids (BCAAs) have been used by top bodybuilding and other athletes for years due to their ability to support their training goals. BCAAs are comprised of three powerful amino acids - leucine, isoleucine and valine - and are perfect for any hard-training athlete because they serve as key building blocks of muscle. They can also help to combat muscle loss and protein breakdown, especially intense training. Promotes Muscle Protein Synthesis Platinum 100% BCAA 8:1:1 is branched chain amino acid formula designed with a potent BCAA ratio of 8:1:1 (leucine, isoleucine, valine). Unlike other BCAA pills that use ratios like 3:1:2 or 2:1:1 Platinum 100% 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 100% BCAA 8:1:1 ensures that your muscle are primed for musclebuilding. ‡MuscleTech is America's #1 Selling Bodybuilding Supplement Brand based on cumulative wholesale dollar sales 2001 to present.
