Many people have stated that deca is good for the joints, but I am having a hard time finding, credible medical studies supporting this. If this is true that means that it is either potentiates the repair of cartilage and or ligaments and tendons. if can some body drop a link of a sound study to support this, instead of just experience or opinion. (I would greatly appreciate it), if this is the case then a intrarticular knee injection of a small dose in the synovial membrane should be very effective in treating lig or cart injuries. of course as we all know articular corticosteroid injections are more harmful than good as they, inhibit healing, decrease cell permeability, and decrease local immune response (risk of infection). As a anablolic injection would increase healing decrease recovery time, decrease the risk of infection (septic joint), but the knee would remain swollen for longer than corticosteroid injection, d/t the increase in cell permeability the knee will swell slightly after injected if not all ready, it will not reduce the pain immediately (like corticosteroids) and may produce the sensation of a unstable knee until the swelling is releaved. If it works it should save your knees from annoying and expensive arthroscopies. I injected my knee a few days ago after a repeat injury, 50mg of deca into the synovial membrane. (I wouldnt recommend anybody doing synovial injections unless you are experienced in doing them) I was hoping to find other medical professionals who might be doing this already and i have found nothing. I will post on the progress if anyone is interested. (I guess I am the ginny pig)
