I'm debunking this myth once and for all. When you mess with your male hormones, DHT peaks and falls. If you don't know what DHT is or how it contributes to male pattern baldness, then you don't even deserve to comment on the whole TRT thing.
Those Vitor pics that appear to show Vitor smaller than he normally is, are at an off angle showing his new weird haircut. The man likes to fuck with his hair.
This frontal picture of the same video shows he looks exactly the same, it's only his hair that is detracting from his regular "image"
It looks a lot worse from profile view or from an angle. Because his hairline has receded even further, it may or may not be because of the TRT and his hormones spiking and then falling. But, regardless of that, he HAS receded a lot. And his new haircut has exposed a lot of forehead and isn't a harmonious haircut for his facial features or his large forehead. That's all it is.
PLUS, his body isn't that much different. There's older videos of him looking around about the same size next to Ariel. Just search "Ariel Helwani Vitor Belfort" on YouTube and you'll see. Yeah he may be slightly smaller because he is retaining less water (less estrogen), but he hasn't lost any muscle mass. NO, he hasn't lost any muscle mass and he still has a good chance of winning. That's all.
