Tobey is spot on. We have already explained that ECA is a combination of ephedrine, caffine and aspirin. It can be a very effective thermogenic agent when taken individually or in a suppliment like Xenedrine where they are already combined at the correct dosages. This is obviously a more convienient administration. However there are other combinations that are refered to as ECA mimickers that create a similar effect on the metabolism, but to a lesser extent. In Canada we can legally posses steroids (we can't buy or sell) but we cannot buy an ECA suppliment OTC. When we buy Xenedrine, Ripped Fuel, Hydroxycut or any other branded ECA stacks we are usually getting a combination of Ma Huang, Guarana, kola nut which is an herbal equivalant fo ECA.
