Yessir jda is on the point.
The effects of the ECA stack in weight loss are primarily due to the ephedrine component. Ephedrine acts both as a beta agonist and stimulates the release of norepinephrine. Increased circulating norepinephrine in the body then acts on white adipose tissue by increasing cAMP levels. This causes a thermogenic effect, raising body temperature and increasing the user's metabolism in conjunction with the rest of the stack.[citation needed]
However, the body's negative feedback system then activates to normalize the metabolism. This is done via the production of phosphodiesterase inside the cells, and prostaglandins outside the cell, which both lower cAMP levels within the cell.
Caffeine inhibits the production of phosphodiesterase inside the cell and therefore slows cAMP breakdown. It also binds with and competitively inhibits adenosine receptors in the brain, triggering the release of epinephrine and increasing cAMP levels further.
Aspirin inhibits prostaglandin production outside of the cells, which, in conjunction with caffeine, greatly prolongs the thermogenic effects and increased metabolism by sustaining elevated cAMP levels.[citation needed]
Ephedrine also has an anorectic, or appetite-suppressing, effect. However, these effects only last for about two weeks if the stack is not cycled, as the body becomes tolerant to ephedrine to some degree.[citation needed] It is estimated that 60%–75% of the weight loss from using the ECA stack comes from the anorectic effect, and the remainder from thermogenesis.[citation needed]
The final component in weight loss of the ECA stack is that of a simple stimulant; the higher epinephrine and norepinephrine levels result in increased aerobic exercise performance and less fatigue.[citation needed]
Ephedrine acts to increase energy by its actions as a sympathomimetic amine. It directly acts in the brain to increase the release of norepinephrine into the synaptic cleft, and also partially serves as a norepinephrine reuptake inhibitor, thereby also partially functioning as a dopamine reuptake inhibitor due to the shared action between the two terminals. Caffeine blocks adenosine receptors which lessens feelings of tiredness, and also increases dopamine levels, resulting in greater concentration, focus, and memory. The effects of caffeine on dopamine levels are usually short lived, but ephedrine's partial action as a dopamine reuptake inhibitor lengthens the duration.[citation needed]
So typically you have 25mg Eph 200 mg caffiene and 81mg of baby aspirin (white Willow) or to get technical Salix Alba there u go. I have done so many research on this eca has made its way to ecy using Yohimbine for a good bed session I mean lol in place of the "a" ^_^. But eca does work JDA got it all dialed in and as cardio hes right I actually do that too ^_^ empty in the morning bc cortisol levels are less preesent and metabolic rate is up after the cardio (afterburn) metabolism is elevated for a greater longer time ok thats enough too much info im giving out lol.
