ECA

Ephedrine - Used primarily for thermogenic fat loss (also as a nasal decongestant) by stimulating the release of adrenalin. An easy way of looking at it is the adrenalin stimulates beta sub 2 and beta sub 3 receptors which allow for fat mobilization to occur. The downside of ephedrine is it?s not very accurate in which receptors it stimulates, along with various beta types, alpha types are also stimulated to some degree and we don?t want this! Alpha sub 2 receptors when stimulated will prevent fat mobilization out of cells and if fat can?t get out it can?t be burnt as fuel. The solution to this is Yohimbine if you read on?


Most people use too little to get the desired effect because they only come in 8mg pills now, when it was available as a fat loss supplement they came in 25mb tabs and two were often recommended. Today? standard ECA stack contains 20-25mg ephedrine, 200mg caffeine and 80-325mg aspirin The above dosage should be taken 3 times a day with at least 3 hours in between. It is also recommended that your last dose should be before 6:00 pm, or you may have problems getting to sleep. Some people recommend only taking the stack 5 days a week with 2 days off to allow your body a small break from the effects. Others stay on it 7 days a week. Again this is a personal thing so you may want to experiment. Along the same lines, some people will use the stack for weeks without stopping. Other's will cycle the doses i.e. 2 weeks on then a week off etc. It is recommended that 4 weeks would be about the maximum that you should stay on the stack without a break of at least a week. The basic rational is that your body will become used to the ECA stack stimulation and the effects will wear off. By taking a break, it is possible for your body to reap better rewards when you go back on the stack. The wired up feeling is likely to diminish within 1-2 weeks of starting the stack. Evidence shows that the fat burning properties of the stack still continue well after that time, so do not assume that an immediate break is needed. . I?d like to note that ephedrine doesn?t work the same on everyone, I have some kind of natural ephedrine resistance and less than 100mg won?t do anything for me, I?ve even gone much higher than that. Most of the people I know that have used it preferred around 50mg and that?s what I recommend too for best effect in the majority of people, but start off at the lower dose to see how your body reacts to the ephedrine because if you are getting great bennefits from 25mg of ephedrine no need in taking more.

Caffeine - Inhibits phosphodiesterase (a catalyst enzyme that lowers cyclic AMP levels inside cells), as well as promotes epinephrine (adrenaline) release which increases cyclic AMP even more. To simplify, it allows cyclic AMP to stay in your system longer without being broken down and helps to increase it. I think I?ll skip explaining the role cAMP plays since most of you wouldn?t care (it?s a dry topic), it translates hormonal signals between cells is about all you need to know, needless to say we need it in order to get that fat burning.


Aspirin - Aspirin inhibits prostaglandin production, which prolongs the thermogenic effects of ECA and increases metabolism by sustaining elevated cyclic AMP levels. Aspirin is a mild uncoupler of oxidative phosphoralation; its metabolic effects at reasonable dosages are minimal. In obese women aspirin may have a more significant metabolic effect. From a fat burning perspective, generally with respect to the EC stack its impact is negligible - you don't NEED aspirin for it to be effective.

Yohimbine - An alpha sub 2 adrenergic receptor antagonist and is best suited to solve the problems associated with ephedrine and alpha sub 2 stimulation. It is also ideal for women because their bodies contain significantly more alpha sub 2 receptors in certain fatty areas than men do which is why they have such a difficult time losing fat around their thighs, butt, etc.

Works much the same as Ephedrine by stimulating the release of adrenalin, it?s widely believed to be more effective and can either be used as a substitution for Ephedrine or it?s also fine to take it with Ephedrine (YCA or EYCA). 5mg or 7.5mg should do, they usually come in 2.5mg tablets.
