This is one of the reasons I have mixed feelings on the idea for PED Olympics. It's trivial to not get caught just using regular ol' test prop. I'm confident that the overwhelming majority of professional athletes and olympians participating in sports where increased strength and muscle mass is beneficial are doing it, because getting caught is hard if you have even a rough idea of when you're likely to be tested and the incentives for doing it are just too high, especially since you're getting paid on those contract years where you're not suspended, and people that get suspended still get contracts after. Much of the benefit persists as long as you keep protein intake up and continue resistance training, too, so you can juice for 5 years and keep a huge chunk of that muscle mass indefinitely. You won't get the additional CNS boosted effects from DHT derivatives or taking some halo right before, but it's still a hell of a big advantage over someone natural.
I think ideally the illusion would just be broken for the masses on just what the state is of pro sports, the olympics, etc., and just... accept it. Having a second set of competitions where some of the biggest performance enhancing drugs are already being used by the majority in the first set doesn't make a lot of sense to me. But maybe them being open about it will usher in people realizing this and accepting it.
Though the 'role model' aspect might mean everyone just keeps lying for forever, because think of the children.
