ECA - ECA stack

Ephedrine, Caffeine, and Aspirin, a popular and effective thermogenic combination of drugs used for weight loss and energy. Ephedrine is a stimulant that acts to increase alertness, energy, and body temperature, thus increasing caloric expenditure. Caffeine inhibits the body's natural tendency to counteract the stimulant effects of ephedrine, so that the two of them used together increase caloric expenditures more than the sum of the increases caused by each one used individually. The most common dosage is 200mg of caffeine taken with 20mg of ephedrine ( = 25mg of ephedrine hydrochloride) three times per day, the third dose being taken not later than dinnertime. Caffeine and ephedrine act as appetite suppressants, which has weight-loss benefits as well. 60mg of aspirin (about a quarter of a standard aspirin tablet) is often added to the stack, but studies have not shown conclusively that ECA is more effective for weight loss than ephedrine and caffeine without aspirin. Please note that ephedrine and caffeine also have a diuretic effect, so some weight loss will be due to a loss of water and not fat.
