Supplementing with alanine post-workout can help combat muscle breakdown and promote protein synthesis. 1G GLYCINE (AS GLYCINE, WHEY PROTEIN ISOLATE, AND WHEY PROTEIN CONCENTRATE) Gylcine is an amino acid which has been noted to play a role in the formation of many other biological compounds in the body, such as proteins and creatine, and even supports cell volumization. 1G TAURINE Taurine is the second most-abundant amino acid found in muscle and aids in cell volumizatio
