Looks great! I would believe he's in the mid 180's, but could be 190's. Either way still looks great, especially conditioning. Good luck bro!
Stan probably was a natural a long time ago, but I don't remember him bashing roid users. He promoted natural bodybuilding in the past, and if I remember correctly on the discovery channel, when the subject of drugs were brought up he didn't disrespect any bodybuilders who were on the gear.
