I like the idea of NPP, Deca and EQ for their increased collagen synthesis to help my 51 year old joints, but I have a drug test for a non strength related sport in a year, which counts out these 3 injectables. I have looked around other gear for properties which might include increased collagen synthesis, but haven't seen any. Are there any compounds out there which I have missed and might give some sort of relief for my aging joints and not be detected in a year?
