Description Rule 1 BCAA is a premium branched-chain amino acids (BCAAs) supplement that helps you train harder and recover faster. It contains leucine, valine, and isoleucine – the three essential amino acids that your body needs to build muscle. BCAAs help to prevent catabolism (the breakdown of muscle tissue) and support protein synthesis, which leads to increased muscle growth and strength. Rule 1 BCAAs also contain glutamine, an amino acid that supports immune system health and speeds up recovery times. Fitflex offers the best Rule 1 BCAA price in Pakistan, just for you!
