A little history about my right shoulder joint problem. During my first cycle, which I was on 400mg/wk of test e, I used to use heavy weights after I am done with the planned sets with few negative reps. After I finished the cycle, I continue doing the same thing. One day I was doing dumbbell curls with 50lb I moved my right shoulder because it was too much weight for me. Something happened there. I wasn't sure what was it. The next few months I couldn't go to the gym at all or lift any weight. I started sharing my experience with another body building site and I was guided to use deca with test. Once I started the cycle, all my joints started to feel better gradually to the point that I have never experienced before. My shoulder problem healed completely and I started using very heavy weights that I couldn't even imagine before.
Now that you know that, I wouldn't say that my shoulder is having the same problem as before I used deca but there is a problem. Even when I move my arms I must be careful and stay aligned.
One thing I remembered today, that I stopped using barbell bench presses in the past because of this issue and I used dumbbells bench presses instead. That what I started doing today. On the other hand, I started today's routine (chest and bis) with external rotations. Somehow I believe this exercise may help this issue.
