i dont know about you guys but, hgh works right away for me, i love it. i wish i could have an endless supply.. you WILL def see results within the first month, you will get great sleep, vivid dreams, wake up energized..loose some body fat, of course the longer you run it the better. but it def DOES NOT take 4+ months to "feel" it.. it will take 6+ months to get full benefits such as the "3D look" or where you can eat anything you want and still loose bodyfat.. it will def help you for the 3 months you run it but, it wont be the dramatic results you might be expecting from it.
