What is ECA?

ECA SLIM refers to a weight loss stack composed of three main components: Ephedrine, Caffeine, and Aspirin. Ephedrine acts as a stimulant, caffeine boosts energy and metabolism, while aspirin helps enhance the effects. Together, they are believed to promote fat burning and aid in weight loss efforts.


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

This extract stimulates the central nervous system (CNS) through release of a compound called norepinephrine. Norepinephrine is used to get the body ready for action and activity. This makes it an important part of the fight-or-flight response during times of high stress.
Ephedra also raises heart rate and can also cause constriction of blood vessels, leading to high blood pressure.


Caffeine is also a stimulant of both the CNS and the cardiovascular system. It’s commonly found in coffee, tea, and soft drinks. Consumption of caffeine can increase feelings of alertness, effectively reducing fatigue.

But when taken in large doses, caffeine can also cause:

  1. Insomnia
  2. Increased heart rate
  3. Elevated blood pressure
  4. Tremors
  5. Anxiety


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

All together, this is a powerful fat burning combination.

  1. Active metabolism
  2. Drop the weight
  3. Shred Fat
  4. Helps with mental focus
  5. Rapid energy
  6. Appetite suppressant

Side Effects


Weight Loss: Ephedrine has long been studied for its effectiveness for weight loss and this could be why people are so hesitant to look elsewhere. Studies show that ephedrine does increase the body’s metabolic ability, promoting fat burning. Ephedrine has been suggested as a potential tool for combating obesity since the 80s. It’s fat-burning effects are especially potent when combined with caffeine.

Energy: A review of several studies found that ephedrine does have an impact on your energy levels, but it seems that you need to pair it with caffeine. Luckily, caffeine is the next ingredient.


Weight Loss: Most people attribute increased energy levels and alertness to caffeine, but did you know that it’s also a thermogenic ingredient? Caffeine has been shown in several studies to increase the body’s metabolic response, increasing energy expenditure or calorie burning. As mentioned above, pairing caffeine with ephedrine promotes a stronger fat-burning effect.

Performance: The main reason that people use caffeine is for energy. Think about it: Chances are that you drank a morning cup of coffee, which contains between 75 mg and 150 mg of caffeine. Plenty of studies have shown that caffeine has a direct and positive impact on athletic performance, which is why it’s found in all stimulant-based energy drinks and pre-workout supplements. You also need caffeine to trigger the energy-boosting benefits of ephedrine.


Weight Loss: The same pill that you take for your headache may also be a helpful way to promote weight loss. Studies show that on its own, aspirin can’t do much for fat burning; however, when it’s combined with ephedrine, aspirin can amplify the thermogenic effect of ephedrine. In other words, the two work together to promote a more effective weight loss.

Inflammation: Aspirin is commonly used post-workout as a way to alleviate inflammation. It’s the main ingredient in many nonsteroidal anti-inflammatory drugs . Studies show that aspirin can reduce inflammation and alleviate soreness attributed to delayed-onset muscle soreness. However, aspirin may also irritate the lining of the stomach, increasing the risk of stomach-based complications.
