If you want to buy ephedra (or ephedrine in this case), just do what GH15 recommends and go to Walgreen's, RiteAid or Long's Drugs, and buy some Bronkaid. Primatene will work too. But I feel the former works much better, for results/duration etc....
It's way cheaper. 60caps Bronkaid for 11.99, and 60 NoDoze for 8.99....
