Leucine could be hailed as one of the more potent natural muscle building supplements known to man. Allmax brings you the purest and most powerful single ingredient to build hard, lean, dense muscle, fast! Leucine (C6H13NO2) is an Essential Branched Chain Amino Acid (BCAA) known throughout bodybuilding as the ultimate muscle-builder. Leucine activates a pathway called the mTOR pathway which stimulates muscle protein synthesis. By increasing Leucine consumption the mTOR pathways is signaled and protein synthesis is increased. No single ingredient has the pure, unadulterated power that Leucine does. Simply stated, Leucine is essential for achieving a positive nitrogen balance and building lean muscle mass The Allmax Advantage: the pure, Pharmaceutical-Grade Leucine crystalline powder is a 100% Animal-Free source! Derived from a pure vegetable (corn), the complex fermentation process yields a clean, white crystalline Leucine powder. There are zero binders, excipients, additives or preservatives in the Leucine product. Allmax did not stop there; Allmax has 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. Allmax has taken the raw crystal material and microparticulated through a complex series of processes; the result, a perfect, ultra-fine white powder that has optimal absorption levels. Beware of your Leucine Source: While Allmax Essentials provides you with the ultimate in high-grade ingredients, there are other cheaper ways to get your Leucine. Leucine, often comes to you from a source of Human Hair (typically from barber shop floor waste), Duck feathers - or both.
