I didnt get a scrip for it, although I could have easily with the cystic acne that I had at times. I went to a mail order overseas company and it got it really cheap. As for liver values, no idea what they are, my dosages are low so im sure they aren't all that bad. Your right though, it is some SERIOUS shit.
Thats one thing that i would recommend, try a low dose for the first month or so (20-40mg ED), if you arent getting the results you want, then up the does from there by 20mgED. I wouldnt go higher than 80mg ED because the sides can be extremely uncomfortable from what I hear. Even if you get it cheap, its still expensive. 5 months of accutane will easily cost you $700-800, even at a low dose. So try low dosages, could be all you need anyway to clear you right up, and it wont be too bad on the wallet, leave some more $$ for TEST!
