i know this is a stupid question but id just like to hear all your opinions on ephedrine free weight loss products. since they stimilate your heart and cause rapid heart beats even tho they dont contain ephedrine. i done soo many cycles of hydroxycut and loved it. but im kinda getting paranoid to use it again since lack of sleep and rapid heart beats. has anyone died from the use of hydroxycut or xenandrine? dangerous or no??? feed back pleasesorry im emberessed lol after all im asking a question newbies ask but trust me i know better lol.just wanna hear all your opinions lol dont flame me.
