I don't think anyone is suggesting he should STAY on winny. No one STAYS ON winny, at least no one with the brain power to operate a computer and be reading this. The question was how to put on quality mass, and not much of it if we're talking 4 mph, in order to reach a goal. The prop will offset any overdrying by supplying enough of IM water without bloating him and he can't use deca because it'll show up 18 months later. Connective tissue shouldn't be an issue in only 8 weeks. I would not suggest he does this "during" the season. Competitors at that level can very easily get hurt using winny during the season.
