I'm about to purchase this product, I've been taking liquid collagen protein, msm, boron, and glucosomine sulfate to help rebuild the cartilage in my shoulder. I had distal clavicular osteolysis (weight lifters shoulder) and just got my surgery in jan. I have been cleared to lift but the pain is awful when I try to work my chest, still bone on bone friction. Will this help ? I am not familiar with the type of joint blend.
