As a pharma guy, I can keep keep you ahead of the doping agencies most of the time. They always catch up, but we’re very good at figuring out new molecules to tickle receptors or otherwise affect physiology. If you’re willing to accept some risk of a) compounds without widespread testing b) possibly being caught eventually, I can give you an edge.

I think a lot of top athletes are willing to take those risks to be competitive and would be shocked if there wasn’t a lot of doping still going on.
