Aspirin in ECA Stack

ECA Stack is widely known formulation which stands for Ephedrine, Caffeine and Aspirin.

Researches show that Ephedrine plus Caffeine combination has strong weight loss effect. Why Aspirin was added to this proven combination?

Aspirin was first added to EC stack about 12 years ago by two scientists at the department of medicine at Harvard Medical School.

It is included in the hope that it acts as a prostaglandin inhibitor and an enhancer of lipolytic activity. The wast majority of studies were in fact done on the Ephedrine plus Caffeine combination. The value of adding aspirin is questionable. Aspirin is supposed to add to the stack's effectiveness by decreasing the body's natural resistance to the stimulant effects.

I believe it not to be an essential ingredient; indeed, many people are intolerant to Aspirin. Another thing worth noting is that ECA has some anti-catabolic properties, which means that we can retain some muscle even while cutting.
