i get noticeable fat loss on 1IU/day after only about 1-2 weeks. are you sure your stuff isn't bunk? maybe you got a hold of a bad batch or left it at room temp too long or got shaken to hard some how. who'd you get it from?
and you said that you have been "dabling" . . . what the F does that mean? you use it for a few days and then not for a few days...? you have to stay on it consistantly or your waisting your time with it
if you have real stuff and you have been using 8 months STRAIGHT (no dabling) at 2-4 IU.day, than you should have def seen some results by now. if nothing else, at least fat loss., sleeping heavier, more energy and over-all well-being
