So the IV is banned in part(perhaps largely) because it can be used as a masking agent, yet nothing in the IV could possibly be detected or lead to a failed test? That means the only recourse for the testing body is to actually witness it? If that's the case why would Floyd even allow anyone to know he got one? It's unfair if Floyd was given an exemption Manny couldn't have gotten(although the painkiller is quite a different thing), and I don't doubt you can't trust USADA any more than just about any other organization in boxing, but this just doesn't seem like a story to me.
