My take on this is Vitor IS CLEAN, but doesn't feel like he has the right to judge others for it, given his past steroid abuse.
When I clicked this thread, I expected to dislike Vitor either way ... If he admitted ro TRT i'd be like "great another cheat". If he sounded of on TRT users, I'd be thinking "yeah, you have room to talk mr nandrolone"
Surpringly this weird convoluted half answer makes him more likeable to me. He probably doesn't approve steroids or trt anymore, but he feels has no right to judge, having done worse himself. He basically dodged a controversial catch 22 the reporter was trying to force him into.
