I need real Ephedra--please help!

I have never used real ephedra so I dont know what its supposed to feel like or how it differs from the feeling of a bunch of caffene so someone could really fool me. I was looking at green stinger until I read to stay away from a product if it says ephedra extract (tip when buying any kind of product u should stay away from it if it has extract written on the label because u dont know how much of the real stuff is in there if any) anyways.....I'm trying really hard to find the real stuff but its so hard now because theres a lot more ephedra fakes then there are reals so if anyone knows please contact me at nessav1992@yahoo.com
