Several things for this one. Many of the treatment variants and/or rare effects aren't either even written yet or coded, considering back when it was implemented, The Treatment then is what Bess/Ben is now: a massive behemoth of text and code that made Fen burnt out on it. It'll probably be worked on again at some point, almost positively after Myrellion, considering that's the current market goal, and the start of the free year, at which point all the other stuff can be gotten back to and prettied up to match current quality/quantity (he said, hoping that the quantity thing was both right and wrong), thus including the Treatment.
As for save scumming the Treatment, are you save scumming before or after you take it? All tf's from the Treatment are decided when you take it, unlike something like horse pills, which are random over their course, so make sure your save us from before taking it, not after.
