that wasn't a guest posing. he showed up to a show looking like that. he was natural for 8 months or something, apparently he had something to prove to himself. after this, he faded into bolivian and never came back to bodybuilding.
More asinine comments...
It was a guest posing, at one of Jon Lindsays NPC shows....Chris was off season and off the sauce for some time, but wanted to honor his commitment he made some months earlier to appear. In retrospect, he should have cancelled.
And he didn't "fade into oblivion"...he made a decision to retire from competition to have a family and secure a future for his family from something more stable...
