Besides his jaw, I'm not sure how you're reading that much into it from one low resolution picture. Especially considering the first picture is a higher contrast lighting scenario. The colour temperature of the first shot is also contributing to the general sense of him looking "healthier". I agree he obviously looks more muscular in the first shot, but you're making a bit of a stretch with the "feminized facial structure" business.
Posture. Collarbone skew. Look at the first one. Its perfect posture, no hint of collarbone skew. You can plainly see it straight across.
Granted in this case, it was probably excessive structure from the anabolic abuse. And you're right, he has mostly just lost his abused size. But once you come off that stuff, there is not a return to normal testosterone levels that you had. You are basically sackless, producing below average testosterone levels for the rest of your life, Vitor already disclosed his struggle with this publicly the year he had to come off TRT. He wasn't happy about where his levels were at. Some guys fare better than others, but NOBODY is able to recover the natural testosterone level they had before taking endogenous hormones.
I don't think its as much of a stretch considering his estrogen is sky high, testosterone is low, and his obvious softening of appearance. Look at the skin quality difference on fight night, pictures aside. Its pathetic to let former TUE's compete as they have already aged into the sport. They should be grandfathered in. A TUE should have been a lifetime license, not an annual thing. Hypogonadism is not a condition subject to change year to year, its a lifetime diagnosis that is usually never rechecked on except to make sure the TRT is at an appropriate level. The TUE itself is not granted year-after-year. For comparison, a TRT prescription in the United States requires only 1 blood test, just one time, to qualify. The doc sees you annually, but there is no further blood work unless you ask for it.
I can take a blood test to anywhere in the USA, from 1999 from 2004, it doesn't matter. And the TRT clinic will make me sign a contract that says I am absolutely not receiving TRT from any other source, and that I give permission to release existing records from my previous TRT. They don't retest if the diagnosis has already been made. Makes sense. Apparently the wada USADA vada blada didnt give a shit about the health of these fighters.
You either have the condition that requires TRT or you don't. This was some dark ages decision-making, and ruined this guys career. TRT had to go, but it was wrong to treat existing TUE's this way.
