You would need to apply to the governing agency within your sport to be given clearance for testosterone replacement therapy. And nobody has ever applied for this waiver.

It would be too easy of a loophole to get around.

And 'Testosteorne replacement therapy' isn't bound by any strict set of guidelines either. There's nothing that says you can't take a supraphysiolgical dose and claim that to be your TRT. Like I said, this would never fly.
