Bros i am on my 6th week of my cycle now consisting of test ent 600 mg/ew. and i tried this out for the past two weeks. week 1 i did all dumbell exercises. (shoulder, chest) and week 2 i did all barbell exercises. but the funny part is that every time i do barbell exercises my left shoulder gets a pulling pain and looses power. its hard to explain. i never had a shoulder injury before.. any suggestions..
