Does he get drug tested?
Doesn't look natural at all.
He competes in the PNBA. As mentioned earlier, he won the PNBA World championship in 2019. He placed 9th at the INBA Natural Mr. Olympia. While binging on the Generation Iron movies, that's where I first saw him, particularly
Generation Iron: Natty 4 Life.
That movie covered the 2019 INBA Mr. Olympia, where 2-time defending champion, Rob Terry, was going for the 3-peat.
Oketch calls himself, "Chris 3-in-1", because he's a bodybuilder, strongman, and fitness athlete. One of the videos I posted has him billed at 6'4" and 120 kg (265 lbs). I'm not sure if that's his bodybuilding competition weight or his strongman weight. Obviously, he looks a lot bigger, in strongman mode.
