Everyone in SPORTS is juiced. The only reason cycling gets such a bad rap is that they actually give a shit about catching people. Do you know how unlikely it is for an NFL or MLB player to be tested? On the Tour de France for instance:     "After each stage, four riders are tested: the overall leader, the stage winner, and two riders at random. In addition, every rider is tested before the first day's stage, normally a short time-trial. Most teams are tested in their entirety at some point during the three-week race. Additional testing may take place during the off-season, and riders are expected to keep their national cycling federation informed of their whereabouts so they can be located. Many teams have their own drug testing programs to keep the team name clean. Teams, such as Quick-Step, have pulled riders before they compete in major competitions. Tom Boonen was pulled for cocaine before the 2008 Tour de France."     They keep multiple samples for years after the fact so that when a new, unknown PED is discovered, they can go back and retest samples. So yeah, they catch people juicing in cycling but that's only because they give a damn about doing so. Look at Mark MacGuire and Barry Bonds, MLB was too busy counting their piles and piles of cash to give a shit if they were cheating.
