The ECA stack is a popular drug combination, which is often used as an energy booster and for weight loss. ECA is an acronym for ephedrine, caffeine and aspirin.
Ephedrine is the main ingredient in the stack for both fat loss and enhancing. Although it's very effective by itself, combining it with caffeine causes it to be much more so. How effective could it be? When used properly and can greatly speed up body fat burning process and you'll loose those unwanted pounds. But before you venture out and buy ECA stack there are some what exactly you need to understand about.
Together with fat loss ephedrine will endeavour to burn off your hard earned muscle too. The best way of combating this fat loss is to supplement with protein throughout the day - not just a couple of times a day, out of the box usually the case.
Ephedrine also serves as diet. How this works isn't fully understood, however this aids in weight loss also. Unfortunately, these effects only last for a couple of weeks when the stack isn't cycled since the body become tolerant of ephedrine to some degree.
Ephedrine acts to increase energy by functioning on the brain to improve the discharge of nonadrenaline into the synapic cleft, as well as works as a nonadrenaline reuptake inhibitor due to the shared action between the two terminals.
In most cases the ECA stack is taken 2 or 3 times daily inside a 1:10:10 or 1:10:15 ratio of ephedrine: caffeine: aspirin. These ratios vary across studies and across users, however in spite of the differences they seem to be effective. No more than 25mg of ephedrine, 200mg of caffeine and 325 mg of aspirin should be taken in just one dose and since ECA stack can contribute to insomnia it shouldn't be taken past late afternoon.
Although ephedrine and aspirin aren't addictive caffeine is, and users can be cultivated a ability to tolerate lowered adenosine levels and this can lead to withdrawal symptoms from adenosine sensitivity if caffeine me is stopped too quickly. It's also easy to develop a psychological addiction to ephedrine and aspirin.
Probably the most serious risk factor of the ECA stack may be the effect ephedrine can have on a pre-existing heart condition. It's been linked to death in individuals with valve damage, cardiac hypertrophy, along with other heart problems. Stimulants should not be taken by anyone with heart problems. Evidence also exists that demonstrate the long-term utilization of amphetamines can lead to heart damage, but this has not been shown for ephedrine use.
Using ephedrine and caffeine may also raise blood pressure level, so users who curently have hypertension have to be careful the stack doesn't raise their blood pressure level to dangerous levels - especially during exercise. The good thing is that the presence of aspirin within the stack does thin the blood and counteracts this partially.
Insomnia, dry mouth irritability, stress, headache, dizziness, irregular heartbeat and increased thirst are some of the other side results of the ECA stack. Ephedrine continues to be associated with death causing many countries to outlaw or manage it. The chance of ephedrine has caused many people to test "ephedrine free" stack formulas. There isn't any proof that any of these formulas are effective, but a great deal of evidence exists to support the effectiveness of the ECA stack, however with risks.
