I have been doing a little research about the ECA stack (Ephedrine ,caffiene,aspirin). I have been talking to a few guys at the gym about what they use as a "fat burning" suppliment. Some say hydroxycut but most say Ephedrine ,caffiene,aspirin. When I asked what each does and why take that stack they come back with "becasue thats what I was told to do."

Now me...before I start taking stacks or anything I don't understand I want it explained to me. So I am asking for some help with this can someone explain why this stack and why is this stack so good at burning fat?And what does each part do?

Thanks for your help.
