He's been discussed in quite a few forums, mainly due to his poor eating habits and excellent physique in very little time training.
If he is natural, he's a phenomenon. Even people like Reg Park and Rob Hope, some of the most genetically gifted people I've seen, took many years to attain the physique you see in their pictures. Of course, they paid attention to their nutrition too.
If he's not natural, he still looks great.
We can scrutinise and point but at the end of the day, drugs or no drugs, this guy does have a much greater genetic potential than most of us. And let's be fair, how many of you have irrefutable evidence that Ronnie Coleman, Jay Cutler or other IFBB pros take anabolics? We know sizes like that are unattainable without drugs, although I still find forums discussing if they are natural or not

, but they've never come out and said it (apart from Lee Priest, whose the only one I've ever heard even mention steroids).
I have attached a pic which seems to me to be him (I can't honestly tell) a few years back. I can't see this guy being naturally big, although his friend looks to have a big arm.
