I injected 0.5 vials of Godtropin 240 (12 IUs), and measured at 31.8 ng/mL after 3 hours. The other picture is pharma grade HGH (4mg = 12 IUs) injected SubQ blood levels over the course of a day. The values seem comparable. I didn't get an IGF-1 test, though. I did the test in April, but didn't get around to posting till now. I'm hoping this is a good sign, plus the product was ordered a while back and sitting in my fridge. Only thing was, I didn't really "feel" anything, no tiredness or numbness, but I've read about studies involving high-dose growth hormone, and only a minority get side effects.
