BRANCHED CHAIN AMINO ACIDS √ Muscle Tissue Growth and Repair √ Muscle Breakdown Inhibitor √ Anti Catabolic Amino Acids √ Improves Nitrogen Balance √ No Impurities √ GMP & HPLC Standards √ Micronized - High Absorption √ Imported from Japan Improve Muscle Endurance and Strength* MVP's Pure 100% BCAA 5000 Powder provides a 5000 mg blend of the three Branched Chain Amino Acids (L-Valine, L-Leucine and L-Isoleucine) per serving. The Branched Chain Amino Acids (BCAAS), named because of their unique branched chemical structure. They are essential as the body cannot produce them from other compounds. In recent times, these amino acids have been investigated for their potential anticatabolic (preventing muscle breakdown) and anabolic (muscle building) effects.
