I have a funny thought; perhaps bodybuilders, we should create a sort of new bodybuilding competition federation in which bodybuilders *must* appear in the nude.
First, you could tell whether their balls are shrunken or not. Apparently this is the number one most obvious indicator of steroid use. Because the feedback loop is simple; if you are injecting foreign testosterone into your body, signals to your body that you no longer need to naturally produce your own Testosterone, which is the hormone which comes from your testes, a.k.a. your balls.
The reason why I think this nude bodybuilding competition is such a good idea is that why is it that male nudity is so taboo? Porn, pornography, is so mainstream now, nobody really seems to care. But yet, there is still a taboo about male nudity?
