Muscle Octane is the branch-chain amino acid (BCAA) product from Anabol Naturals. BCAAs, L-Leucine, L-Valine and L-Isoleucine, are incredibly powerful amino acids because they're metabolized directly in the muscle tissue. BCAAs are critical for two of the most desired results in sports performance: energy production for muscular work and anabolic processes within muscle cells. A post-workout must for feeding hungry muscle tissue.
