Total Hydro Whey GoldNutrition® is a delicious protein shake composed of the highest quality whey protein, hydrolyzed isolate. This formula contains OPTIPEP® 90, a high-quality protein produced by CARBERY®. CARBERY protein is obtained from whey from cheese production made from milk from cows predominantly fed on grass. Hydrolyzed whey isolate protein is the most easily digestible protein with the highest absorption rate, and for these reasons, promotes faster muscle recovery after exercise, with greater stimulation of muscle protein synthesis, leading to greater muscle growth.
