I would use orange triad as your multivitamin. It contains joint support: msm, chondroitin, and glucosamine. These will help repair joints, cartilidge. Orange TRIad also contains immune support, digestive aids and hefty vitamin dose. This one product will help signifigantly giving you a strong foundation.
Cissus is also great for reducing pain and helping rebuild connective
tissue. I recommend Blue Gene.
Not only does Blue Gene contain cissus, but also will boost test and regulate/control estrogen.
I assume your using some sort of narcotic (painkiller). These make your test levels drop signifigantly. Blue gene will help you get back to where you were. It will also aid in fat loss and energy.
The last two things are CLA and amino acids. The aminos will support fat loss and rebuilding muscle tissue. Two good amino products are Purple Wraath and Xtend. CLA will support fat loss and joint health too.
Let me know if I can be of anymore help.
