ECA Stack

An ECA stack is a combination of ephedrine, caffeine, and aspirin tablets. When taken together, these ingredients are said to promote weight loss and boost athletic performance.


Ephedrine is derived from the Ephedra plant. It’s been used in traditional Chinese medicine for centuries and is also referred to as “ma huang.”


Caffeine is also a stimulant of both the CNS and the cardiovascular system. Caffeine consumption can increase feelings of alertness, effectively reducing fatigue.


Aspirin is a pain reliever. When taken as part of an ECA stack, aspirin prevents norepinephrine levels from decreasing. Helping maintain the stimulation effects that the caffeine and ephedrine help provide.
