They say that Accutane elevates liver enzymes. You are supposed to fast for 12 hours prior to getting your bloodwork done while on it. I didnt fast, I ate every three hours all day before getting my blood work done, and my enzymes were barely elevated at all. I did notice some joint pain though while on, so I could see how that would deter one from a heavy cycle. I also noticed I was very crabby and depressed while on Accutane, so that too probably wouldnt be a good combo with juice.
They say that if you have a history of acoholism in your family, as do I, that your liver will learn to adapt and be tougher than most people's. Maybe thats why my enzymes werent elevated too much.
