Yes he is still competing but not using occlusion anymore.
I know what you are saying. I used it a few times with an IFBB pro that I worked with. The first time he was freaked out by the size of the pump. But the subsequent times he didn't get the same effects and we did not notice any additional gains compared to regular training so I concluded that it is not worth the hassle and health risks.
I will not use it again with any body. I will not recommend it to anybody. If you like it, fine you make your own decisions, but I will personally not ok it.
