I'm not sure what it is and I've seen some commentaries on what is going on.
Fillers is one possibility but he seems heavier in general but hard to be sure, would be interesting to know what's happened to his bodyweight.
Could it be some type of publicity stunt where he's intentionally done something, via cosmetics, to get people talking?
Could he have some health problem where he's on cortisone or what have you?
It's not due to GH, though he's most likely on PEDs currently.
