MHP’s BCAA 3300 is a super-anabolic Branched Chain Amino Acid complex formulated in a powerful 4:1:1 ratio (leucine: isoleucine:valine) for maximum muscle building and recovery. This highly anabolic ratio sets MHP’s BCAA 3300 apart from other formulas that use the outdated 2:1:1 ratio. The newest muscle building and performance research reports that leucine is the most anabolic of all amino and activates the mTOR anabolic pathway to increase protein synthesis for enhanced muscle growth and repair.
