He just had to be made an example of, by people he had pissed off. And he was brought down by his own disgruntled teammates. Not by a + test.
It's widely known that athletes at the highest level have encountered people who use roids. If you just don't inject yourself to the gills with it and cycle out, you stand a good chance of passing the test.
You can use it and compete with the rest, or you can choose to not use it and watch the others run past you in a pace you thought was supernatural.
Bikers used to drink alcohol and climb the hills in the Tour all the time. Is alcohol not performance enhancing when it dulls the throbbing pain in your legs?
Bring those cyclists down too. Then you'll have everyone's support.
Make a league for people who want to use roids, and for the ones who don't. It'll multiply your revenue 2x, organisers.
