It is a common fact that each of the compounds in the ECA stack has its own effect. Used as a single entity, Ephedrine enhances the noradrenaline hormone levels and prompts the adrenergic system, which makes the Noradrenaline to react and stimulate the brain to increase the cardiovascular activity and promotes the release of glucose and the flow of blood into your muscles. This boosts your brain’s power to perform and concentrate on tasks including your workout routine.


On the other hand, caffeine has a significant role in repressing the constant urge to eat and snack recklessly. Caffeine is also responsible for diminished epinephrine action, which in turn boosts the tasks carried out by ephedrine. With Aspirin, its major roles include blood thinning which leads to faster circulation and a more rapid release of fats from the cells to be used in the energy production. This means you will have less fat deposits. Aspirin also plays a huge role in inhibiting hormones that curtail the efficiency of ephedrine.
