Big daddy you should do a search on this site and others for the effects of large doses of Glucosamine & Chondroitin. As I was serching some months ago I ran across several posts from guys who had fracked up thier knees, typically from heavy squats, and claim to have rehabbed them over the months with big doses.
Personally I had a problem with my elbow and I took 9 motrins a day for many, many months and while I can still feel it it doesn't stop me from working out. I also have a physical job. That was before I heard that several of the NSAIDs are hepa toxic so i am not sure I would do that again.
As a last, and most expensive resort it would not be unreasonable to expect that several months of hGH might strengthen that tendon.
Now as to your joints if you are refering to an arthritis-like problem of degradation of the cartilage then you should try sAME. Got my Dad on it for his arthritis and he reports that it seems to be helping him. Google sAME and get lots of good info.
If you find anything interesting make sure to share it with the forum, I would be interested to see what you come up with. Good Luck!
i had bad elbows also, i couldnt do conentration curls, chins and a few other exercises, doctors told me to lay off the weights but i didnt, what i started to do was when i worked my biceps i started with barbell curls but i did 4 warm up sets with really light weight and high reps and then did my normal 4 sets and after a few weeks i no longer have any elbow pain at all and my elbows had been bothering me for over two years.
My 2 cents. CMO (Cetyl Myristoleate) with Glucosamine/chondroitin. Also fruit pectin(Certa brand) with fruit juice. Taste like shit but works. Tablespoon with grape juice. I consult with doctors and I don't listen to them when it comes to training. Good luck. There's other stuff but they block my suggestions.
I'm in the same boat and I powerlift. I use my fish oil, wear my elbow sleeves, but what has really helped me is ending at least 2 of my workouts per week with super high rep tricep movements.
Like rope pulldowns for 100 reps or "pistons" (downward punching motion) for 100 reps in as few sets possible. It's done wonders. Read some of Dave Tate's stuff, I think that's where I got the idea from.
