it's a perfect drug if you're bulking, but it won't do anything for you if you're cutting really; it won't help preserve protein, and in fact, it may do detrimental things, because it can cause your fat cells to replicate. the energy releasing properties of GH on fat are direct and not shared by igf-i.
depends what you want to do. i'd run a heavy cutter with t3, clen, 500mg+ of test, and some other androgens, then turn around and bulk up clean with igf-i and a good run of androgens.
