Build and preserve lean muscle. Enhance recovery from training. Free form for rapid absorption & delivery. GAT BCAAs: Fast, easy support of lean muscle building & recovery. GAT BCAAs capsules contain all three branched-chain amino acids – leucine, valine and isoleucine – in free form and a 1.6:1.4:1 radio. The free form (not protein bound) supports rapid absorption and delivery to your muscles. Plus, we’ve added co-factors to support your metabolism. Our capsules are tested to ensure that they meet or exceed United States Pharmacopeia guild lines for dissolution (i.e. release of ingredients). The BCAAs play important roles in muscle energy metabolism, recovery (from exercise) and the regulation of muscle protein synthesis. Supplementation with BCAAs stimulates muscle protein synthesis, which helps muscle tissue build and recover.
