Sorry, I just realized my post had nothing to do with the original question. PB is right, don't get the rHGH in bulk, just buy 4-15iu vials in bulk.
Question for PB:
How bad has your water retention been w/ rHGH?
I have tossed around the idea of using a potassium sparing diuretic. It would only be for cosmetic purposes, I just hate being bloated.
