It doesn't matter how heavy you go on deca. Joints are like butter on real deca. My joints get like butter on most andro based steroids because of water retention in the joints but deca is something different. It has the ability to help promote joint tissue and bone growth. If you take an anti-inflamitory, and deca, and ice for 1-2 months on deca, you can cure many joint problems including torn tendons, cartliage and nerve damage and even some ligament tears can be healed with deca treatment. The key is if you are already injured to rest ice and suppress the imflamation for a long time until totally pain free and then build your strength up from as low a level as possible, meaning go as light as you can until the minor pains while moving are gone, should take about 3-4 routines if you took enough time off to rest the tissue, without reagravating the injury, for my elbow I rested for at least 1 month before I started the deca and for 2 months after I didn't lift with my right arm, and then for the last 6 weeks of the deca I lifted progressingly harder and by the end I was healed. I had entrapment and axon of the ulnar nerve in my right elbow, torn nerve in my funny bone area, was fucked for a long time. I deca rehab cycle and I was golden. Fake product, test or a prohormone or something.
