Im not sure what your asking... but if your asking is ephedra alone better than ECA, the answer is a clear resounding NO. This is commonly understood.. The caffine raises your body temperature along with the ephedrine to a degree or so above normal to burn fat, and the caffiene works as a diauric which means your also loosing water retention weight. At the same time as this the Asprine is blocking fat, so your getting a much much much better and more effective product with ECA.
That ECA stack looks like it has a good dosage of everthing... if you want slightly better results you could always bump the ephedrine up by another 25mg for a tiny extra expense to your pocket.
