Corruption in officiating worries me too, and you're right that a biased gatekeeper could poison any system. But that's a flaw in governance, not in the drugs themselves, and the fix is transparent medical oversight, not a ban. A black market already has corrupt gatekeepers, and they're unaccountable, unlicensed, and lethal. We don't abandon referees because some took bribes. Regulated PEDs keep the decision in daylight, where bias can be heard and corrected. That's a cleaner chord than the silence of prohibition.
