unlesss you are planning or trying to make a living as a pro bb i dont think you should be taking gh at your age...i know will go in one ear and out the other so to answer your question in what only would be my "opinion" is you should stick with a smaller dose of 4 to 6 units a day MAX...5 on two off.....this is NOT a 8 week get freaky drug....it only works by taking it over a long period of time and to avoid fucking yourself up you must keep it at a safe dose.......use your brain bro and think about your organs not you muscles...the gh is for old fucks like myself and ironmaster but i strongly suggest at your age you should not take it or if you do please dont abuse the shit.....
more is not better
