ECA; What's the science behind it?

[New2Anabolic]

I know that ECA works well as a fat burner, just like Clen .

Or at least it aids in the journey.

But I wonder how, what exactly is happening? I don't mean to ask a complicated question, I mean I'm not looking for a highly educated answer, but just the main idea behind it.

Is it all thermogenic?

[kick6]

aspirin is a vascodialator. Ephedra and caffeine are both stimulants that operate in different ways. The stack essentially increases bloodflow in the body, and raises your metabolic rate.

i believe clen is by far superior

[magicstick2003]

ECA is a CNS stimulant which works synergistically to promote increased metabolism. Ephedra stimulates beta receptors which basically when stimulated boost metabolism, which raises heat production within the body and essentially burns more calories. Caffeine is also a mild stimulant which will mildly increase body temp. both are sympathomimetics which means they mimic the response in the body which adrenaline produces (fight or flight). They also have mild alpha recptor stimulation (within the heart) thats where you may notice a little higher pulse rate when on them.
Aspirin prevents platelets from sticking together (does not thin out the blood as some people think) Got this offline, Aspirin enhances and prolongs thermogenesis by inhibiting prostaglandin production.

i agree though clen at least to me is far superior. I think scientifically speaking ti has a greater degree of stimulation then the ECA does.

You also risk your heart too though, far more with Clen .

What should I dose ECA at?

So far, this is exactly what I'm looking for, thank you !

[magicstick2003]

this is true clen does stimulate alpha receptors in the heart more. Someone on here was talking how it could possible be beneficial to cardiac cells.. (some study they said it was in, no clue though on that)
umm dosing is normally in the area of E- 25mg, C- 250, aspirin i wanna say a baby asp will do but i can;t remember off hand. I do know the E:C ration is 1:10

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 substaining elevated cAMP levels.

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]


[edit] Mechanisms of effect in energy gain
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]


[edit] Dosage
Typically the ECA stack is consumed two or three times per day in a 1:10:10 or 1:10:15 ratio of ephedrine:caffeine:Aspirin. These ratios vary across studies and across users but despite variance they all seem to be effective.[citation needed] Usually, no more than 25 mg of ephedrine, 200 mg of caffeine and 325 mg of Aspirin is consumed in a single dose. It is not recommended that the stack be taken past late afternoon as this may contribute to insomnia.


[edit] Addiction
While Aspirin is not physically addictive, caffeine is, and users develop a tolerance to lowered adenosine levels, leading to withdrawal symptoms from adenosine sensitivity if caffeine use is discontinued too quickly. Psychological addiction to ephedrine and caffeine are also possible.


[edit] Risks
The primary risk of the ECA stack is in the effect of ephedrine on the heart. Ephedrine has been linked to deaths in people with valve damage, heart problems and heart disease, but also in previously healthy young adults when taken in high doses. It is not recommended that stimulants be taken in users with a pre-existing heart condition. Additionally, there is some evidence that the long term use of amphetamines can lead to heart damage, but this has not been shown for ephedrine use.

Caffeine and ephedrine also act to raise blood pressure by approximately 4 – 7 mmHg on average,[citation needed] so users with existing hypertension must be careful that the stack does not increase their blood pressure to dangerous levels — especially during exercise (for example, by lifting exceptionally heavy weights).

Other risks include insomnia, dry mouth, irritability, stress, euphoria, headache, anxiety, dizziness, nausea, irregular heartbeat, interaction with MAO inhibitors, trembling hands, increased need for water and potassium, and psychosis resulting from the long-term use of ephedrine.


[edit] Controversy and legality
Due to deaths linked to ephedrine and its potential use as a precursor in illegal methamphetamine manufacture, many countries have taken steps to regulate ephedrine. If ephedrine cannot be obtained, pseudoephedrine, ephedrine's optical isomer, can be substituted, but many countries are restricting sales of over the counter pseudoephedrine as well, because it is likewise used as a precursor in methamphetamine manufacture. Contrary to popular belief studies have shown pseudoephedrine to have a thermogenic effect; approximately three times less than L-ephedrine.[citation needed]

Many people have felt that ephedrine is not worth the risks, and have tried "ephedrine free" stack formulas. However, there is no proof that any of these formulations are actually effective, whereas a great deal of evidence exists to support the effectiveness of the ECA stack,[dubious – discuss] albeit with apparent risks.


[edit] Status in The United States
Currently in the United States, ephedrine is legal, but the FDA bars marketing any supplements containing ephedrine as weightloss or bodybuilding supplements. To be legal, ephedrine must be marketed for medical conditions such as asthma. In addition, the FDA recently barred the sale of herbal supplements containing ephedra (a herb which contains both ephedrine and pseudoephedrine) under any circumstances. Ephedrine is still commonly available as a bronchodilator in several over the counter asthma medications from companies such as Biotek and Vasopro as well as in Primatine tablets.

As of 4/14/2005, U.S. District Judge Tena Campbell struck down the FDA's ban of weight loss supplements containing ephedrine alkaloids in the US, which may pave the way for its reintroduction as a weight loss supplement in the US. The ban on marketing ephedrine as a weightloss supplement at the moment is being challenged by several companies. A judge in Utah has ruled in favor of a pharmaceutical company that challenged the FDA's ban and the company may once again release products containing ephedrine back into the market.[citation needed]


[edit] Status in Canada
In January 2002, Health Canada issued a voluntary recall of all ephedrine products containing more than 8 mg per dose and products containing combinations of ephedrine with stimulants such as caffeine.[1] 8 mg Ephedrine, 200 mg caffeine, and 325 mg or 500 mg Aspirin can be bought separately.

perfect.

thank you.

CLEN & TEST E would be my final decision... most likely. although I do fear heart dmg.

[magic32]

Good ECA info above fellas!
-------------------------------
And Magicstick is awfully close the stack formula is 3-2-1.
Eph 30mgs (25mgs in some blends)
Caff 200mgs
Asp 100mgs (baby asp 81mgs)

And yes, Clen does promote a very similar action (via the Beta-2 rather than all Betas) but on a more potent level.
