i'm pretty sure there are idiot guides out there, but essentially...
store in original vial in the fridge(although recent tests indicate the stuff's stable enough this isn't necessary, it will still be more potent), and never dilute unless with the original diluent, beit BA or AA(dunno which igtropin uses). when you go to do a shot, load a very small amount -- 4 iu's would be 40mcg with most of these -- and fill most of the rest of the slin syringe with bacteriostatic water or vitamin b-12 so you don't eat clean through your flesh like some morons have done.
shoot im twice a day. some people shoot bodyparts they're training but that's pretty pointless because exercise doesn't upregulate your IGF-I receptors like it does for slin. you will very likely experience local site growth. much better for bulking than cutting; igf-i has been demonstrated to not have any protein preservation properties, but the anabolism is just sick, even apart from the hyperplasia.
no need to taper or anything coming off. it will suppress your GH production to some degree based on dosage, but nothing severe.
