Maybe not exactly on the same level but...I have degenerative disc disease in my back. I wake up in the morning and can't bend over at all and my back usually aches. I can usually bend all the way down after about being awake for 2 hours. Hell, I even bought a 4000$ dollar temperpedic bed with no help. I've been on HGH for a little over 2 months now and the pain has all but disappeared. Still have a very slight problem bending over in the morning but the difference is night and day.
I would think it would work very well at combating degenerative joints, but I'm no Dr. by any far stretch of the imagination (I just tell the girls I am) .. I would definitely give it a try at least, maybe add in some OTC or prescription support as well - I've had good results with Cissus extract and Gluc/Chon/MSM is a good stand-by as well as fish oil, but those are old news .. good luck bro
