Thanks. I think at this stage, doping is probably more prevalent in amateur circles, trying to enter the 'big leagues' in various sports, than in the very top-level sports.
Just as a sidenote, here in Norway, any time there is a bodybuilding/fitness competition, which normally consists of everyday people with regular jobs who train hard, the police have a field day tracking them down (using or selling drugs/steroids is a criminal offence here). It's been pretty well documented that as soon as the officers enter the building, scores of contestants flee the premises. A public flogging would probably be the most efficient way to combat this.
As for the one guy I'd like to see endure a slow, painful, death by penis removal with a blunt object, it's this guy:

He ruined an entire sport throughout the 2002 olympics (was caught the day after the closing ceremony). He ruined the careers of skiers trying in vain to follow him, running themselves into the ground in the process. Some of Europe's finest endurance athletes, training for years for this moment, had their Olympic dream shattered by a renegade, degenerate idiot. So what was the moment when I myself realized he was crocked? During the very first competition, when he made a mistake and stumbled head first into the snow. In cross-country skiing, this is almost akin to pulling a hamstring on a football pitch. Your entire body will react negatively to this disruption of the high-pulse, high-muscular intensity where you're always just a few seconds away from building destructive lactic acid. Instead, he just whizzed away, looking stronger than ever. It says a lot that he immediately after the first race had to answer serious questions regarding doping allegations. Anyone with half a brain and knowledge about the sport knew that this performance was way beyond what was possible by natural means. Feck him. I hope his apartment is invaded by cockroaches.
