for you to get any benefits from gh no matter what brand you need 4 units per day 5 on 2 off for a min of 3 months...the main use for gh in adults is for aids patients or anti-aging which is what i use it for...using it for bodybuilding imo leads to the abuse of it and some potential side affects you sure dont want....i have used it for a couple years now never taking more than 4 uints a day and the only sides i've had are some stiff hands and i stay on for months at a time....guys slamming a dozen or more units a day all look the same, huge guts and fucked up jaws and foreheads and those are just what shows on the outside..my guess they have some major growth in their organs as well
