I don't know if you guys will believe this, but there's strong evidence that shows that more than 20GMS a sitting, will result in waste. There's a study done by a Canadian university, which shows that everytime you take in more than 20GMS, your synthesis (amino acid count) maintains at a level below 20GMS but another synthesis count (the one that shows your urine levels stuff) increases.

It was a consistent study and the researchers have been led to believe that this shows everytime you take excess protein, the body will take the amount it can use (perhaps higher post workout) and drain the others. Many bb'ers have went "WTF?Ｕmad!??" and I would have too, but the Chinese weightlifters have shown that this theory may be consistent.

Their diets consist of things which are nutrient dense with stuff like vitamins and minerals, essential acids and not just protein protein protein alone.

May be something for you guys out there to ponder about.
