Monster View Sports science tells us that BCAAs (branched-chain amino acids) are the most crucial amino acids for muscle-growth & strength. Around 33% of muscle protein consists of BCAAs. Intense exercise can cause BCAA levels to drop rapidly. This could result in muscle-tissue breakdown (catabolism) & fatigue. Supplementing with BCAAs could result in superior muscle-growth & strength, plus increases in muscle power output. BCAA NANOSTACK contains the ideal 2:1:1 ratio of BCAAs. It is refined into micro-crystallised powder, so you are assured of the highest possible absorption & retention. Vitamin B6 is also included which contributes to rapid metabolism of BCAAs. With 3g of L-leucine, 1.5g of L-valine & 1.5g of L-isoleucine per daily serving, BCAA NANOSTACK is one of the strongest formulations you can buy.
