Well, I used to drink a whey isolate shake after training and also vitargo (carb source), did notice a little extra fullness. But now with the Whey hydrolosate after training, I'm holding more muscle while dieting down than before. I assure you that in the next few months, Hydrolyzed whey will be the new hot supplement. The protein is already enzymatically reduced to Micropeptides and requires virtually no digestion. The nitrogen retention is way beyond whey isolate per gram of protein.
