In 1992 AST released the first whey protein to the sports nutrition world. Building muscle has never been the same. Whey protein technology has advanced more in the past 7 years than any other supplement category. The advancement in whey protein science has been staggering.

Whey protein is a broad description of a protein fraction derived from milk.
What this means is you can have a very poor denatured whey protein concentrate and a highly refined whey peptide isolate and label each one whey protein. In fact, if you are using another protein besides VP2 Whey Isolate then you are not putting the latest science to work for you. Building lean solid muscle requires a daily intake of protein. Muscle is protein. Without this essential nutrient all the training in the world won't help you.
