winny is a 17aa so it does survive the 1st pass through the liver, but that does make it very hepatoxic, winny one of the most hepatoxic steroids out there. so you shouldn't run it as long as a nomral inject cycle if you plan on taking it orally.
winny is water-based not oil-based if i'm correct
and goose some people aren't able to get whatever type of steroid they like, so they have to stick with what they can get, (me for example)
