I have pretty bad back/chest acne and was wondering how hard it is to get this stuff. Can I just walk into the dermatologist's office and ask for it? I got prescribed some antibiotics once for acne and they didnt do shit, plus I couldnt take them with milk (I drink a ton of milk when bulking) which was a pain. And how bad are the sides? Someone I know got it and all they had were chapped lips.
