I don't think he can be "reversed." The only guy that I've ever seen do anything similar to reversing the effects of the size game, was J.D. Dawadou (sp?). Came in huge, then cutback on his size and went for symmetry and proportion, got hosed at a show and promptly disappeared from the scene and retired.
I think the only thing that can help Branch, and I really wish I was wrong, would be to retire or take some serious time off- from drugs, the sport, training, and just rest his body.
