The true strength of BCAAs. The branched chain amino acids leucine, isoleucine and valine are valued for their anabolic and anti catabolic properties. Used in the 2:1:1 ratio before and/or after endurance exercise they may help spare muscle tissue. Used after strength training, BCAAs help kick start protein synthesis which plays an important role in muscle growth. We also included 5 grams of L glutamine because this conditionally essential amino acid may help support recovery after intense exercise.
