Pac has only increased 4 or 5 pounds on fight night since he's been at 130. If he's on steroids he's doing a shitty job for gaining only a few pounds. At 130 he was what 145/146 on fight night, and when he fought Cotto he was 149 on fight night.

So I don't know where he gained 17 pounds of muscle in 18 months come from.
