Used before endurance training, the Branched Chain Amino Acids (BCAAs) Leucine, Isoleucine and Valine can help spare muscle. Used after strength training, they help kick-start protein synthesis which plays an important role in muscle building. ON's BCAA 5000 Powder delivers 5 grams of BCAAs per serving in the preferred 2:1:1 ratio of Leuncine to Isoleucine and Valine. It's instantized for easy mixing into water, juice or post-workout shakes.
