About 10-15 pounds it's hard to say with the water retention..It was actually a friend of mine I put on that exact cycle your on and he's real lean and tall..He filled up and looked great and he didn't even eat anymore protein then you would off cycle..But he's got great genetics..Anyways he's a boxer so he had to lose the weight when a fight came around, but the 10-15 pounds made him look like somebody you might take two looks at instead of the muscular "crackhead" look he's got going now..
