  • BCAA 4500 from AST Sports Science



  • Delivers 3 branched chain amino acids



  • Supports muscle strength and recovery


AST Sports Science BCAA 4500 delivers three branched chain amino acids: L-Leucine, L-Isoleucine and L-Valine. These are naturally occurring molecules that your body uses to build lean muscle proteins. BCAAs are the only amino acids that are metabolized directly in muscle tissue and help to prevent muscle breakdown, promote muscle protein synthesis, provide fuel for muscular energy, speed muscle recovery, enhance endurance and support anabolic hormone production.
