HGH and increased size?

I am 25 years old. As a new year plan to get in shape and have a ripped masculine figure I've started a series of strength building, muscle building, fat cutting exercises supported by very potent "legal" stimulants. I have started to build lean m and introduced a human growth hormone into my horde of other supplements. I ordered this HGH from the Czech Republic from a bio chemist friend of mine. (Highest grade HGH molecular level available) He was not able to answer my question so I have started posting the question on the internet hoping to find a good answer. After 3 weeks of taking this HGH my size went from 6.5 inches to 7.8 inches witch was great. The wife was loving it and so was I. However, after 7 weeks it measured in at 9.3 inches. This is actually causing my wife to have an unpleasant (sometimes painful) experience in the bedroom and it is getting hard to hide in the gym. Extremely embarring trying to hide this monster in gym shorts. I don't know how most black guys do it. I have been off of the HGH for 5 weeks now and the size has not decreased at all. I am wondering if any other guys out there has had this effect from HGH and if so....Did it go away?
