As Roman has suggested, I'd look into TB-500. I'm dealing with shoulder issues at the moment as well, however for me my shoulders feel good while training, but they get sore soon after I get home. I'm resorting to significantly dropping the weight and focusing on form and time under tension. If you watch some Kai Greene videos, he advocates exactly that. Lifting as heavy as possible is not the only way to develop a world class physique... however if your main goal is strength, then that is an entirely different story. Also, do you incorporate internal and external rotations into your workouts for rotator cuff strength. We tend to forget about the muscles that we can't see develop because their goal is not for aesthetics, but rather to support the larger muscles that you can physically see developing on a weekly basis.
