Right on magg...yeah, I didnt even get into down regulation which granted, happens much later with ephedrine as compared to clen lets say. My idea essentially was that through my experience of watching uneducated people use ECA's.. they use a poor diet throughout which ultimately gives them ENOUGH boost to shred a few pounds. They get hooked on it and notice the results and desire to keep using it. So they keep running it for a long time, past the point where it is effective for them. At this point, not only have they stopped fat loss, but have potentially acquired a dependency to the stimulant.
