Aljazeera investigates the dark side of doping in Sports

The Aljazeera TV News Channel recently aired a programme which showed just how easy it is to obtain drugs for doping in sports. In countries where there is little out of competition and no biological passport profiling, it's very easy to take illegal supplements while training and be completely clean by the time a major championships comes around.

While much of the programme is focused on American football and baseball, it does show what the anti-doping agencies are up against.
