Five athletes tested positive for the stimulant bromantan and were disqualified by the IOC, but later reinstated after an appeal to the Court of Arbitration for Sport: swimmers Andrey Korneyev and Nina Zhivanevskaya , Greco-Roman wrestler Zafar Guliyev and sprinter Marina Trandenkova , all from Russia, and the Lithuanian track cyclist Rita Razmaitė . Dr. Vitaly Slionssarenko, physician to the Lithuanian cycling team and team coach Boris Vasilyev were expelled from the games.    The CAS overturned the IOC decision, because bromantan had only recently been added to the prohibited list,  and the athletes and officials were reprimanded.    The Russians had argued that bromantans wasn't a stimulant and thus not banned.  
The bottom line then, is that doping seems to work VERY WELL. It’s still difficult, if not impossible, to put an exact number to the benefit, though the data of Franke et al give a pretty good indication that it’s at least 15% in those power based sports. It may be slightly less for endurance based sports, like cycling. But as i wrote yesterday, there’s substantial evidence that hormone levels, particularly testosterone fall during the course of a race like the Tour. And so if Floyd Landis and others are using the drug, the benefit would come from defending this drop-off, which promotes recovery and hence allows them to maintain their form throughout the Tour. In theory then, the systematic use of drugs will have a large effect in cycling, not because it acutely boosts performance, but because it allows it to be maintained. Think of your own training – you always have good days and bad days. But what if I said that by using a drug, like testosterone, you could drastically reduce the number of bad days – that is what these drugs will do for cyclists.
