just curious what you should avoid taking while on clen? i know of course that you shouldn't take any other stimulants along with it (except maybe a little caffiene here and there). however, i think i remember someone saying somewhere that taking viagra or cialis while on it was "asking for a heart attack".
anyway, if someone who really knows their stuff knows what to avoid taking while on clen, please let me know. i'd like to pop some viagra as i just came off pct and i can't get a decent hard-on for the life of me, but i don't want to risk any heart issues because of it.
