You extrapolated his logic into something he has never said, believed, or practiced. And then pointed out why that doesn't make sense.
You're literally making the exact argument he's making.
So as you are now agreeing, I used his line of reasoning to form my own opinion, and did not put words in his mouth.
He’s saying basically that clearly 500 grams of protein ISN’T being used to build muscle because if every gram of protein was a gram of muscle you’d be huge.
I’m saying just because you don’t weigh as much as you eat in grams of protein doesn’t mean it isn’t being used to build muscle. Yes we know protein is being used for other purposes in the body, but it also doesn’t work like that. In MPS proteins are produced from polypeptide chains created by ribosomes. It’s not a gram for gram conversion. That is what I’m saying doesn’t make sense.
As it has already been stated, we just don’t have studies on bodybuilders on gear and how much it takes for them to get to that size and grow. So scientifically, no, we don’t know how much protein it takes or what the limits are. The studies we have are only in average people, and even then their responses to protein intake vary by A LOT and it has to be assumed this comes down to genetics.
With just about everything in this sport, there is somewhat of a standard based on what we know, and then there is the logical recommendation to recognize that everyone responds to everything differently, food, aas, and training, therefore it’s best to test things on yourself and find what works best for you.
