im doing 75 mg tren Ace ed. So far i hit the delts both left and right in the past 2 days... i havnt gotten any soreness in them ... can i continue to just do delts. This is my first time doing it.. i am uneasy around needles and my brothers doing it for me. Is there anything wrong with rotating just the delts, or would it me important to use other muscles as well in the rotation.. regardless if im getting sore or not....
thanks
