How does the ECA stack work?
Ephedrine Caffeine and Aspirin are all stimulants in their own way. They work together in a synergistic fashion to increase your metabolism so that you burn calories faster. I will sometimes take them before bicycling to work in the morning. Just don’t fall into the trap of thinking that if a little bit works, then taking more will work better. ECA is dangerous if you take too much. People have died of heart attack because of too much ECA. So beware. In fact, if you are just starting out, then start with half a dose instead of a full dose. But it is generally safe as long as you stick to recommended dosages.
