Welcome to ECA Stacks

The effects of the ECA Stack (Ephedrine, Caffeine and Aspirin) in weight loss are primarily due to the Ephedrine component but not its sole reason by any measure. Ephedrine stimulates the release of both nor-epinephrine and adrenaline into your system.

This increases the circulating nor-epinephrine in the body, which then acts on white Adipose tissue (fatty tissue) by increasing cAMP (Cyclic Adenosine MonoPhosphate) levels. This causes an increased thermogenic effect, thus raising body temperature and increasing the user’s metabolism in conjunction with the rest of the stack (Caffeine and Aspirin).

However, the body protective system or negative feedback system then activates to normalize the metabolism and body temperature. This is done via the production of Phosphodiesterase inside the cells, and prostaglandins outside the cell, which both lower cAMP levels within the cell and this results in a neutralising of the effects, meaning you cool down and return to a normal state.

This is where Caffeine comes into the stack since it inhibits the production of phosphodiesterase inside the cell and therefore slows cAMP breakdown quite dramatically, making the fat burning process last longer. It also binds with and competitively inhibits adenosine receptors in the brain, triggering the release of epinephrine and increasing cAMP levels further. In simple terms it prolongs the break down and thus effect of the ephedrine while simultaniously having its own boosting effect, so its a double whammy.

Now your wondering what Aspirin does?, well it blocks or inhibits prostaglandin production outside of the cells, which, in conjunction with caffeine, greatly prolongs the thermogenic effects and increased metabolism by sustaining the elevated cAMP levels.

Many people find they don’t need the Aspirin in an ECA Stack which maybe true but since its such a cheap and readily availablae product, its not really worth worrying too much about it, if you want a true ECA Stack buy it, otherwise don’t worry about it either.

Some people are allergic or sensitive to Aspirin or Salicin in general, so a good alternative is L-Tyrosine, which it has been proven that L-Tyrosine is a far more effective prostaglandin inhibitor than Aspirin, so it should further boost the effecrts of an ECA Stack above and beyond simple Aspirin. L-Tyrosine also has a number of benefits within its own right such as aiding with tanning, moon enhancing and more.

Its not generally a product that occurs in ECA stacks because a dosage of 750-2500mg is required which would would leave no room in the capsules for other ingredients. Generally speaking people buy L-Tyrosine in bulk packs and add 2g to their drink of choice to gain the benefits, so its suggest by some to use a drink loaded with L-Tyrosine to aid swallowing your ECA Stack for maximum results.
