The anabolic attributes of deca will indeed take weeks to kick in....however, I'd bet you'd notice a quicker response from deca's attribute of joint pian reducton. Maybe less than a week if you're lucky?! Drink lots of water and wait a week or two (max) for deca to eliminate pain in joints. In the meantime...You can also try fish oils---great for pain reduction and lubricating joints (not as potent as deca though). Probably 6-8 capsule/day is a good estimate.
