Don't like or reccomend ephedra / ephedrine and I've used a bunch of it for party and asthma. I don't think its dangerous or anything, just eats up to many vitamins and the energy/power you get is taken back X2 when you quit. If I wanted to take a route like that I'd go with a cleaner, scripted amphetimine. No actually I don 't like any uppers when trying to maintain a healthy body. Best route is always better food and more cardio.
BTW folks, you can check your cattle for injectible ephedrine (ephedrine sulphate).
