I have been on Hgh(nutropin) for about a week prescribed by my doctor. I got using this hgh cause my doctor figured that my androgen receptors were down because when i was using test cyp 1cc for a month i didn't feel a bulge from it. so he decided to check my endogenous gh to see the levels, come to find out that i was on the low normal range. He then decided to start me off with 1iu for a week, 2iu for the following week, then 3iu continuous. i have only been on this regime for about a week and i already feel like a million bucks, i could take naps now, libido is increasing, skin getting tighter, muscle mass increasing, well-being is through the roof. I'm writing all of my experience on this cause i notice that there are some percentage of people that are on trt and still don't feel it, maybe this will be an insight on what might be wrong cause i know how frustrated i was when my trt wasn't working. So if your trt is not working as much as you expect it in the sense that you still not having morning wood and less of a well being, and checking all other hormone, knowing that they are on a good range, you might have to ask your doctor to also check your growth hormone. If he checks it and finds out that you are in a low normal range, you might be a good candidate for HGH and that could mean that you androgen receptors were down regulated and with Hgh you will be able to up regulate it.
