Product Information

Directions for Use

Suggested Use: One serving (1 rounded teaspoon) 2 times per day. (Take one serving immediately after intense activity). Serving Tip: Pure Leucine by nature basically tastes neutral with a slightly tart or bitter taste and does not dissolve immediately in water. We recommend adding it to your ISOFLEX Protein shake, a flavored mix or juice such as squeezed lemon with an artificial sweetener like Stevia or Sucralose. Mixing with an electric blender is recommended. Beware: If you get cheap Leucine that dissolves instantly, you may need to be concerned about the source of your Leucine. Without additional processing, real Leucine does not dissolve easily or quickly.

Do not use if pregnant or nursing. Consult a healthcare provider if you have been treated for or diagnosed with a medical condition, or if you are using any medication.

Formulation Notes

ALLMAX Leucine Leucine is likely the best single ingredient supplement on the market to build hard, lean, dense muscle, fast! Leucine is an Essential Branched Chain Amino Acid (BCAA) that is known throughout bodybuilding as the ultimate muscle-builder. It's considered essential because your body cannot produce it, so it must be supplied by your diet. 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. Simply stated, Leucine is essential for achieving a positive nitrogen balance and building lean muscle mass.

The ALLMAX Advantage: ALLMAX brings you the purest and most powerful crystalline Leucine powder with zero binders, excipients, additives or preservatives.

In the final stage of Leucine production, the result is a coarse crystalline structure. We've taken the raw crystal material and microparticulated it through a complex series of processes, resulting in perfect, ultra-fine white powder that has optimal absorption levels.
