Branched Chain Amino Acids are named for their unique branched chemical structure and are classified as essential amino acids meaning that the body cannot produce them by itself. Therefore these three BCAA’s, leucine, isoleucine and valine, must be acquired through your diet or supplementation. BCAA’s help create an anabolic environment inside of your body by stimulating muscle protein synthesis, slowing muscle damage post training and aiding in the creation of glucose to help fuel your muscles and further prevent muscle breakdown. So basically, if you are looking to make and keep Gainz…. BCAA-XS is for you!
