im in my 8th week of test E at 500mg per week. first cyle. i never really got any muscle soreness on any of my previous shots but for some reason since the day after my last shot (saturday) ive had the worst soreness ever. i can barely walk. it literally feels like i just got hit in the ass with a baseball bat. hurts to sit, hurts to stand, etc. and im not nearly mobile enough to lift. should i be worried?
