Ok I'm 35 180lbs 13%bf and 5'9. I started to take 4iu of Hgh (somotropin) 2.5 weeks ago. I got a growth hormone level done prior to taking it and it was 3.7ng. I got a blood test done again 2 weeks into it. I took 4iu 1.5 hours prior to the test and my levels came back at 4.6ng. I have not got my igf levels done. What are your thoughts on this?
