From my understanding, You dont really put on much muscle with hgh, and any increase in weight could pretty much be organ growth. But it does make you feel young and gives you a sense of well-being. Its pretty expensive but if you have the money, you could use it along with a good cycle of roids! From my understanding, using hgh, igf1 and some serious bulking roids, you are very likely to keep most, if not all of your gains after your cycle is done. Hmmm adding insulin to that mix would mean even greater results, but pretty dangerous, even if you know what you doing. Hgh on its own, i would think would be a waste on money if you lookin to put on serious muscle mass. as a fat burner, pretty effective where you jab it, but then again to expensive to use just for that.
Well, thats my opinion!
