This is a fat burner that says Ephedra free on the cover and researching it i have found that it is said to have ephedrine in it and other places say it is ephedrine free. I don't know what to think and don't want to take something that has ephedrine or ephedra in it because I play football and don't wanna die running or something. How do i find out whats exactly in this? ANY help is much appreciated!
