I had some bad pain in my shoulders before my current cycle which is Test npp. After about 2-3 weeks they felt better and at 8 weeks now they are about 90% better.

Deca will do a better job IMO. Did a mild cycle of it along with Proviron while recuperating from a small tear on right side rotator cuff, along with sore knee joints, which were killing me. Felt like a Champion during the cycle, It healed my rotator cuff and was able to finish leg workouts to levels I'd done when I was in my 20's without any knee pain. The only thing is the dreaded Deca dick. it creeps up on you, especially after cycle and If you don't want a limpy, better prepare yourself with some caber to counteract it. But for the purpose you want, It'll get the job done and rejuvenate you joints nicely.

wheres stats?

Myself and my wife mwagsgurly use it for cycles and sore joints. She will pin it from time to time just for her knees also

Im on npp now and my joints are feeling pretty good. Not as good as when I ran deca though however im only 3 weeks in on the npp.
