With 23 grams of muscle building pure whey protein per serving, including BCAAs, Driven Whey helps repair muscle tissues, which speeds recovery and maximizes muscle growth. Protein is extremely important for the growth and repair of muscle tissue. Research has proven that taking protein before and after workouts is the best way to spark new muscle growth, speed muscle tissue repair, and gain more lean muscle than ever before. Pure isolate whey proteins are the ideal way to do this, because they contain key muscle building amino acids. BCAAs are amino acids that are not produced in your body... instead, they have to be introduced into the body through diet. Pure isolate whey protein powder ensures your body is getting the adequate dose of daily BCAAs in order to gain strength and mass while guarding against loss of muscle, because it is rich in whole chain amino acids leucine, isoleucine and valine. Training increases the need for BCAAs, which make up one third of muscle protein including it before and after workouts is essential to getting the gains you work for.
