It appears, Deca contains collagen properties, that help sooth inflammations in connective tissues. Contrary to popular belief, deca does not repair structural damage. I have joint problems, and I have taken deca to ease that achy feeling and it worked. However, it was just temporary relief, after concluding my cycle, my joints went right back to feeling achy again. I guess it would depend on the severity of one's injury that would determine how much deca helped. Eq and Deca are totally different compounds, there seems to be a misconception that these two compounds are basically the same, not true at all. Eq raises RBCs at a higher rate than the majority of steroids, which means it increases "blood volume," consequently, would lead to more oxygen and blood flowing to the tissues, which could contribute to the healing process. However, I personally have not found any evidence that indicates Eq is a remedy for connective tissue issues, but in relation to more blood flowing to tissues, it quite possibly could be some benefit for temporary relief. Nevertheless, through my own experience with these two compounds, I would recommend Deca for the issues you claim that are hindering you.
