may be nothing. in fact i'm not feeling hardly ANY of the normal muscle soreness a day or two out from training as i would while "off". but i am getting severe aches from the way heavier poundages superdrol has assisted me to. i was doing chest just a little while ago & had to stop. my elbows up through my shoulders were aching so bad, i had to let the dumbells safely down to the floor. i mean the "nails driven through my bones" are stopping me from lifting any heavier! just thought it might be some side effect. anybody else experience anything similar to this?
