Hydrolised protein which quickly enters the body system and supports the muscles during regeneration - as quickly as possible. There is no whey protein that works faster and is as pure and sophisticated as Platinum Hydro Whey from Optimum Nutrition. There's only one word for it: perfection. According to this special formula, the protein is hydrolyzed. Hydrolysis breaks down large proteins.

For added effectiveness, Optimum Nutrition has added digestive enzymes and branched chain amino acids (BCAA's) to this revolutionary formula. Hydro Whey not only works fast, but is also protein in its purest form. It is obtained exclusively from hydrolysed protein isolates from whey. Therefore, there is no excess fat, cholesterol or lactose to slow your progress.
