I went to the gym quite often and wanted to find a way to shed off a little more body fat and tried a EC stack (no aspirin) and while I did lose weight it felt very jittery and uncomfortable. Also upon a doctors visit he reported I had a never before heat murmur. Aspirin also increased the danger of this stack so all in all I really wouldn't recommend it, beset way to lose weight is to gain muscle which will burn fat to support it's self.
