Don’t know for sure buy a guy I know who hangs out at a lot of gyms says that (at least some of the) “natural” bodybuilders use tons of drugs!
It’s a pretty difficult topic-if you were trying to win and could take a drug that is safe, effective, and had only a little chance of triggering a positive drug test, would you take it? What if it’s your whole life? What if it’s the way you put food on the table? is the motivation higher for the guy “going for the win” or the guy “just trying to keep his job”?
I used to say most mornings I was over the limit for caffeine…but I guess it’s off the list now so I’m “riding clean”!
