ECA stack is the combination of ephedrine, caffeine and aspirin used for weight loss and as an energy booster. It was widely used as the dietary supplement through the 1990 but later it was restricted in some states of United States and in Canada. There are several reasons for ECA to be illegal and you should know about the risk before using ECA stack.
As the main ingredient of ECA ephedrine can produce harmful effect on the heart. People who suffer heart disease and those with valve damage and cardiac hypertrophy should be careful using ECA and know that the overdosing and in some cases the use of ECA combined with exercise can cause heart stroke, attacks and even death. However there is little evidence of such serious harm if one controls the level of ephedrine according to individual physical characteristics.
The other fact is that ephedrine burns off not only fat but muscle as well. To avoid that one should use protein several times a day. Ephedrine in combination with caffeine can raise blood pressure and it can be dangerous for people with hypertension regularly exercising.
In comparison to aspirin and ephedrine caffeine is addictive and the sudden break of caffeine use can lead to withdrawal symptoms from adenosine sensitivity. Other side effects of the ECA stack include stress, dry mouth irritability, insomnia, dizziness, headaches, increased thirst and irregular heartbreak.
Now when you know about all possible risks and understand that the proper dosage is unlikely to cause them let's discuss the advantages of ECA stack use. ECA greatly speeds up the process of fat burning and you'll see that you loose unwanted pounds very quickly. Your appetite will be suppressed that also helps you to become slimmer.

The studies showed that the higher level of a single dose shouldn't be more than 25mg of ephedrine, 200mg of caffeine and 325mg of aspirin.
