Well, I know someone had posted about this a while back (I forget who), but he's been juicing up and hitting the weights and apparently getting quite a bit of plastic surgery too (or he's just gone so over-the-top with the steroids and such that it's deformed his face).
I thought these were fakes at first, but apparently, they're all real. Those of you with weak stomachs may not want to click.

If you'll excuse me, I'm going to go be sick now.
