There is nothing subpar about MP's BCAA 3:1:2 and your results will be proof of that. This BCAA complex is pure and all about performance. LEUCINE: With three grams of leucine per serving, it's the perfect amount of one of the essential amino acid powerhouses to help induce muscle growth. Leucine not only has the capacity to stimulate muscle protein synthesis, it has been suggested to slow muscle damage after intense training by increasing the synthesis of muscle proteins. ISOLEUCINE: With one gram of isoleucine, this glycogenic amino acid creates the glucose your body burns for energy. VALINE: Like leucine and isoleucine, the two grams of valine encourage protein synthesis and muscle tissue growth while providing energy from glucose creation. It also acts as a facilitator for normal growth and a reparative agent for various tissues in the body.
