hey guys.... new to the forum but not new to bodybuilding. have a quick question...are there any fat burners on the market that have no caffeine or ephedra and do not cause heart palpitaions? about 6 months ago i started having anxiety attacks....they absolutely suck for those of you who have never had them. it feels like your going to die b/c your heart is beating so fast and you can't breathe. anyway, since this condition started i wanted to try and get something safe but effective that would aid with my cardio and dieting plan that wouldn't fuck with my heart. any suggestions would be appreciated. thx guys!
