Proper supplementation before and during workouts can significantly improve performance. That's where Core ABC comes in. Core ABC is ideal whether bulking up or slimming down. It was specifically designed to promote performance by supporting muscle building, reducing catabolism (muscle loss), supporting endurance; and assisting recovery. Core ABC uses an effective, established ratio (2:1:1) of branch-chain amino acids (Leucine, Isoleucine and Valine), to promote recovery and build muscle. Glutamine is included to help keep the body in a muscle-building state during training, and CarnoSyn brand. Beta-alanine is included to improve endurance by reducing lactic acid buildup and increases skeletal muscle carnosine levels. Citrulline Malate also reduces lactic acid buildup and ammonia concentration, at the same time promoting nitric oxide (NO) and ATP production. Core ABC should be taken before and during training, but can also be taken at other times throughout the day to maximize its effectiveness.
