I know this is an old thread, but if you are like me then you are reading everything you can on the subject to gain a better understanding. I am only 5'8" and 175lbs. I'm not interested in body building but I have always been fit and active. About 7 years ago I blew my ACL, 3 years after that I blew 2 disk in my lower back, (had surgery on both knee and back). I've been in a lot of pain since and put on weight because I couldn't get out and stay active. I have had permanent painful numbness in both legs from nerve damage.
I started on Hgh on the advice from a friend who broke his back. Starting in the second week, 60% of my pain was gone and it's only gotten better. I am slowly getting a little more feeling in my legs, I don't get headaches anymore, heartburn is gone, my skin looks better and I am more active than I have been in 5 years. I sleep better, I've lost weight and I have much more energy to work, play and exercise. I have no idea if it's right for you but it has been a life saver for me. I'm on 2iu humatrope ED mornings with zero sides.
Best of luck.
