NITRO-TECH® is a scientifically engineered whey protein formula, and is enhanced with the most studied form of creatine for even better gains in muscle and strength. It also features whey protein, which is the most popular type of protein. Whey protein is made up of branched chain amino acids (BCAAs) and essential amino acids (EAAs), and has the highest biological value (the measure of how well your body absorbs and assimilates protein). The whey protein in NITRO-TECH is sourced primarily from whey peptides and whey isolate – two of the cleanest and purest protein sources available. Using these proteins on a daily basis is vital in helping to increase muscle protein synthesis for more muscle size and strength.
