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.

Optimum Nutrition Gold Standard Whey

Whey Protein Isolates (WPI) are the purest form of whey protein that currently exists. By using WPI as the primary ingredient along with premium ultra-filtered whey protein concentrate (WPC) in Gold Standard 100% Whey, we're able to pack 24 grams of protein into every serving to support your muscle building needs after training.
