nhbgorilla ... ART is fairly inexpensive. My suggestion would be to go get the problem fixed NOW, then do your cycle. steroids are not going to fix the problem. as for your problem, it is probably both the shoulder AND the pec. if you have a problem in one of these areas, you are guaranteed to either have or a develop a problem in the other. these two areas are so closely related on the kinetic chain, they might as well be treated as a single entity. i guarantee if you get the pec loosened up, the pain in your shoulder will disappear. it is probably being pulled out of proper alignment by the tightness in your chest.
fast twitch... doing work to strengthen the rotator cuff is great, but again, how interested are you in getting back into your training at full go?
guys all i can do is continue to post threads full of guys claiming to be "miraculously" healed. if that doesn't convince you to go get better, nothing will.
