ALLMAX brings you the purest and most powerful single ingredient to build hard, lean, dense muscle, fast! Leucine (C6H13N02) is an Essential Branched Chain Amino Acid (BCAA) known throughout bodybuilding as the ultimate muscle-builder. Leucine activates an anabolic pathway called the mTOR which stimulates muscle protein synthesis. By increasing Leucine consumption the mTOR pathway is activated and protein synthesis is increased. No single ingredient has the pure, unadulterated anabolic power that Leucine does. Simply stated, Leucine is essential for achieving a positive nitrogen balance and building lean muscle mass. The Allmax Advantage: Our pure, Pharmaceutical-Grade Leucine crystalline powder has zero binders, excipients, additives or preservatives in our Leucine product. ALLMAX did not stop there; we've taken the highest-grade Leucine available and made it even better. In the final stage of Leucine production, the result is a coarse crystalline structure. We've taken the raw crystal material and microparticulated through a complex series of processed; the result, a perfect, ultra-fine white powder that has optimal absorption levels.
