Hi arronz,
Personally, I did a lot of research on this as I underwent two surgeries last year - one for my neck (had 2 discs removed and a 4 disc 'cage' built for stenosis) and one for my back (had a lumbar fusion and cysts removed from 2 discs, as well as a laminectomy...also for stenosis). I was a bodybuilder before and didn't want to become a wreck from operations so I looked at testosterone and deca durabolin. The deca is the key since it helps rebuild bone, cartilage and tendon. It also acts like joint lube.
I started 300 mg per week test and 150 mg per week nandrolone 1 month before the surgery and 10 months later I am finally tapering down due to blood pressure issues (it got a little high at the end). I healed amazingly fast and all the doctors pretty much know what happened but I can't admit anything. I am back to lifting over 100% of what I was when I went in, with some modifications, but not many. My first operation was in March and the 2nd in July. Between May and July I actually was forced to walk with a cane due to degradation.
Now, be aware you can't just run deca alone unless you want a limp dick for a long time. Also, I realize that I am probably on TRT for life due to this stunt, even with weekly HCG injections. However, my wife watched me heal and defy expectaions, so both of us are happy. Also, keep an eye on your bloodwork, especially liver function, lipids and red blood cell count. You may generate too many red blood cells for your own good...this almost cost me one surgery since it was just above range.
Anyway, just for stats before surgery I was 5'11" 210, with 16% BF. Now I am almost 6', 215 with 15% BF. I started lifting again 6 weeks after my back surgery at 60% of my best. Be careful with what you do, but research deca...it works.
