This classic fat loss stack has been used for years by people in all kinds of sports - bodybuilding, endurance sports, or athletic sports. What's more, don't forget the "regular Joe" who is just looking to lean out a bit. Nonetheless, few people ask themselves the most crucial questions: Is the ECA stack safe? Is it effective? Are there any alternatives? Therefore, in this article we will go in detail to examine the ECA stack and its uses.
The ECA stack is made up of three ingredients - ephedrine, caffeine, and aspirin. On their own, ephedrine and caffeine can have some benefits when it comes to fat loss. However, when you combine the three compounds, they have a synergistic effect that can speed metabolism up by 10%. This will result in greater fat burning effects and results. For instance, ephedrine has been shown to increase heat production in the body (thermogenesis), which causes the release of stored fat. Upon this release, the fat is used as the body's first source of energy. Meanwhile, caffeine will make the body continually burn fat throughout the day, and it will also increase metabolism. Finally, aspirin works to keep the body's temperature stable, allowing the ephedrine and caffeine to work longer.
The ECA stack has two main mechanisms of action that will lead to the ultimate goal of fat loss - increased metabolism and appetite suppression.
A typical dose of ECA is 24mg of ephedrine, 200mg of caffeine, and 80mg of aspirin taken three times per day. This would be the maximum daily dosage recommended. Nevertheless, the best way to run the ECA stack would be to start slow with 3 doses of 8mg ephedrine, 100mg caffeine, and 80mg aspirin per day. From there on, one can slowly increase the dosages until reaching the recommended dose.
In spite of being very effective, the ECA stack comes with many possible side effects. Some of them include increased blood pressure, insomnia, irritability, anxiety, and adrenal fatigue. For these reasons, it is important that this stack is run no longer than six weeks before taking a minimum break of two weeks. Luckily, the side effect of insomnia can be lessened by taking your last dose at least five hours before bed, or eliminating the last dose all together.
Another side effect is potential catabolism. ECA does not distinguish between fat and muscle. Therefore, together with weight loss and increased metabolism, ECA will naturally lead to some muscle loss as well. This would definitely be considered a negative side effect in bodybuilding because a lot of effort is put into gaining additional muscle mass, and nobody wants to lose it that easily.
