These individuals were eating 20– 30 g/kg/day of protein - far more than most (or what anyone would need).
There must be a typo: "GH on average of 100 mg/day" !!!
How is this even possible?How many bodybuilders actually eat 8,000 to 10,000 calories of protein a day!?! If these guys actually did, no wonder they have kidney damage.
So the 80 kg guy would actually have to eat 16,000 calories/day and the 100kg guy, 20,000 calories/day.
