Regardless of Mike's natty status, one should acknowledge Mike's height and facial aesthetics (no homo), neither of which is achievable via gear. Also, the dude really has to have tendons made of steel cables to lift as heavy as he does, for as long as he has. Honestly, the only thing that makes me just slightly suspect he may be a legit natty is the fact that he seems to be largely injury-free and trains at the upper end of the weight and volume spectrum. That ain't something that comes from a pin. Even the biggest juicebox will break down under those loads (no homo again) eventually.
