Optimum Nutrition’s Gold Standard 100% Whey uses pure Whey Protein Isolates as the primary ingredient. Combined with ultra-filtered whey protein concentrate, each serving provides 24 grams of all-whey protein and 5.5 grams of naturally occurring Branched Chain Amino Acids (BCAAs) which are prized by athletes for their muscle building qualities.

Optimum Nutrition has a history of setting one of the high standards for quality. Each shake mixes up effortlessly using just a glass and spoon, and tastes consistently good, shake after shake.

The amino acids in protein are the building blocks of muscle protein synthesis. A whey protein shake consumed before or after exercise helps kick-start this recovery process.
