Insulin for natty bodybuilding???????

Hey all, I was talking with my training partner today and he was talking about insulin he told me to Start insulin he said "Insulin allows for amino acids and glucose to be pushed into muscle cells, greatly stimulating muscle protein synthesis at higher doses. It will increase testosterone and is a natural hormone" blah blahhhhh

I want to stay natural for a couple more years and dont want to start anything else that isnt natural at this stage



is it worth doing insulin ? or shouldnt i bother ???
