Well I am getting ready to cut and thought that I'd use an ECA sup for some help. I've read around on here and am getting confused. I've read people will take the ECA Stack and then add some sort of ephedra and caffeine with it. Then I look where to get ECA Stack and found ECA EXTREME that has 25mgs of Ephedra extract and 200MG of caffeine already in it. So my question is are people using ECA Extreme on top of a third party ephedra extract and Caffiene or?? Or are ECA Stack and Extreme different things? Sorry for the damn novel just want to be clear.
