you have it reversed.
you have to buy ephedrine meds like bronkaid or primatene.
its illegal for supplement companies to put ephedrine in a product and market it for weight-loss . this is why , aside from research chem sites, all real ephedra weightloss products will be pretty old ( like, expires 2009ish). if it says exp 2013 or something like that you know its bogus.
the current ephedra products out that say ephedra ( leaves) are bogus. there aren't any alkaloids in the leaves. which is why they are allowed to put it in a product and market it as a weightloss supplement.
