Effectively maintaining and building lean muscle mass requires all nine essential amino acids (EAAs). Ensuring your diet has all nine EAAs can be difficult, so Dymatize has developed ALL 9 AMINO —our most complete amino acid powder blend for optimal muscle protein synthesis (MPS) and training recovery support. ALL 9 AMINO contains essential amino acids, such as BCAAs. Essential amino acids cannot be made by the body and must be acquired through protein consumption or supplementation. ALL 9 AMINO supplies 10g of EAAs, including 7.2g of BCAAs.
