the crazy cramps clen causes confirmed my clen is the real deal (I just realized that sounded like a doctor seuss book). i forgot about the taurine. how much taurine should i take? i almost had to go home from work because my left tri wouldn't relax so i couldn't bend my arm. if taurine doesn't work, i don't think i can take clen. my tris and pecs kept locking up.
