>It mostly boils down to people pumping themselves full of steroids up until a week or so before the competition so they test clean. The most common "base" of a steroid cycle is testosterone. If you stopped injecting testosterone a week before a competition, you would still show unusually high levels of testosterone in your blood (even if you were using a shorter ester). But as others have pointed out, they don't test for steroids in most BB competitions. My personal suspicion is that pro BBers who use steroids but deny it do so to protect product endorsements they have.
