Honestly, the only thing you're damaging is your wallet. 2 iu's of GH on a 5/2 split is hardly enough to consider it a "bulking" cycle. IMNSHO-if you're not using a minimum of 4iu's daily of GH(not this 5/2 cheapskate shit) along with a decent amount of AAS and insulin you're not gonna see too much in the line of visible gains. You'd be better off doing a test only cycle any day and the extra $$$ you have left over you could bang a few hookers.
