all i know is that i use jintropin, and on their site you can tell if its real or not.from the reading ive done...4-6i.u a day is good for body fat reduction...8-10i.u a day is good for adding mass...either way, its going to be expensive...divide your daily dose in half, first half in a.m., second in p.m....shoot in in wherever you have fat..pinch the fat tween your fingers, inject it and feel the solution going in, me personally i have been putting in the fat right above my johnson...and ill be damned if the fat isnt starting to go away(no lie!!)
