You can bank on any shoulder injury taking upwards of six months to heal without surgery, and i dont mean completely heal, ive had every shoulder injury possible, torn rotator cuff, 3rd degree ac separation (bad), bursitus, and now im dealing with a torn labrum. Deca is only going to mask the injury. I dont even take ibuprofen anymore because i need to sense the pain to know how far i can push myself. The keys to dealing with all these injuries is patience and taking particular attention to ROM. For example, I will never to barbell bench again, ever.
