the Xenadrene without Ephedra is trash... its like a cup of coffee for me, enough to wake me up, no noticeable results. Go with something with Zotril in it if you are not privy to Ephederine... I don't know too much about it, but claims are that it has close results to ephederine products, but you might want to research it some more. I know Urban Biologics Gut Cutter Z is formulated on Ephederine, as well as the stuff called Zotril, but you can check online or at GNC/Vitamen world.
