The Ephedrine - Caffeine Stack For Rapid Fat Loss.
A Complete Guide To The Ultimate Fat Burning Supplement.


The only supplement which has been consistently clinically proven to produce significant fat loss in adult men and women is the Ephedrine - Caffeine “stack”. Otherwise known as an EC stack.

An EC stack is simply when set amounts of these ingredients/tablets are “stacked together” and consumed at the same time.

Sometimes Aspirin is taken with Ephedrine and Caffeine to create an "ECA stack" (Aspirin is thought by some to add to the stack's effectiveness).

This site explains how to make and dose your own EC and ECA stack, how it works and where to obtain the ingredients.

What is Ephedrine?

Ephedrine HCL (Hydrochloride) is an extract from the Ephedra Sinica plant - a small, twiggy shrub native to the deserts of Asia.

Ephedrine (sometimes referred to as “Ephedra” or “Ma Huang”) has been used in traditional chinese medicine for centuries to treat asthma, bronchitis, coughs and colds.

Ephedrine is also used in modern medicine as a nasal decongestant and is found as an ingredient in many cold and allergy remedies. Ephedrine reduces swelling of small blood vessels in the sinuses which in turn makes it easier to breathe.

How does the EC stack cause fat loss?

Taking Ephedrine and Caffeine in combination causes the body's nervous system to release a chemical called noradrenaline (nor-adren-a-line).

Noradrenaline release makes you feel alert, focused and triggers a process known as thermogenesis. Thermogenesis is when the body “burns” stored fat in order to keep or make itself warm (as would normally happen if you were exposed to cold conditions for a significant length of time).

Noradrenaline release/thermogenesis also suppresses your appetite, so you consume less food and therefore less calories.

The Ephedrine/Caffeine combination is also an energy booster which helps with motivation to exercise and allows you to put more effort in during workouts.

As you can imagine, this is quite a potent combination which has a cumulative effect on fat loss.

Interestingly, bariatric doctors (obesity specialists) have known for some time that just as diabetics produce insufficient insulin, obese people don't release enough noradrenaline.

The EC stack corrects this metabolic imbalance meaning the significantly obese could benefit most from taking the stack.

How do I make/dose the stack?

Clinical studies have shown that the optimal Ephedrine to Caffeine ratio for fat loss is 20mg of Ephedrine to 200mg Caffeine. This should be taken at least twice and up to three times a day.

It is recommended each dose should be taken at least 4 hours apart and no less than 30 minutes before meals.

Many users take a dose 30 to 60 minutes before exercise for a pre workout energy boost.

The last dose should be taken 4 to 6 hours before bed, otherwise (due to the stimulant effect of the caffeine) you may have trouble getting to sleep.

An example of a typical 3 dose day would be...

7.00am - 1st dose.
7.30am - Breakfast.
12.00pm - 2nd dose.
1.00pm - Lunch.
5.00pm - 3rd dose.
7.00pm - Dinner.
11.00pm - Bed.

When you start taking the stack, it is extremely important to begin with a very low strength dose and then gradually increase it to the full 20/200 serving. This will test your tolerance of the ingredients and keep any undesirable side effects to a minimum.

A logical way to start taking the stack and increase the dose strength would be as follows:

key: 1E = 1 x 8mg Ephedrine tab. 1C = 1 x 200mg Caffeine tab.

On the first day, just take 1 half dose to test whether you are hypersensitive (allergic) to Ephedrine (very rare). The dose will be 1E + ½ C.

Times per day
Test dose - 1E + ½C
2 - 7
1E + ½C
2 - 3
8 - 14
1E + 1C
2 - 3
15 - 21
1½ E + 1C
2 - 3
22 - 28
2E + 1C
2 - 3
Full dose - 2½ E + 1C
2 - 3
High dose - 3E + 1C
2 - 3

After 35+ days and if the stack is well tolerated it may be possible to go up to 3E (24mg) + 1C per dose.

The stack works best when the body is well hydrated so it is very important when taking it to drink plenty of water (6 – 8 glasses a day).

As mentioned earlier, Aspirin is sometimes taken with Ephedrine and Caffeine to create an “ECA” stack.

Aspirin is supposed to add to the stack's effectiveness by decreasing the body's natural resistance to the stimulant effects.

However, it is debatable whether Aspirin is necessary as it appears to make little or no difference to the amount of weight lost. Ultimately Ephedrine and Caffeine are the essential ingredients.

Taking a lot of Aspirin also can have an irritant effect on the stomach.

Nevertheless, if you want to make a ECA stack, along with the Ephedrine and Caffeine take either...

  • One 300mg Aspirin tablet (type as used for pain relief).
  • Half a 300mg Aspirin tablet (150mg).
  • One 75mg enteric coated "stomach friendly" tablet (as taken daily to prevent heart attacks).

Some users choose to take Aspirin just with the first dose of the day.

How much weight can I lose and how quickly?

This is a difficult question to answer as it depends entirely on the individual. Some users report tens of pounds simply “drop off” them in a couple of weeks, whereas others see less dramatic, more gradual results.

In order to give things a fair chance, a good time frame the prospective user should expect to take the stack for would be 4 - 6 weeks.

It's important to remember, the stack can help you quickly lose weight but it will of course be most effective when combined with a healthy diet and regular exercise.

Are there any side effects?

Like all medicines the EC stack can cause side effects but not everybody gets them. Some common short term side effects people experience from taking the stack are...

  • Feeling hot/sweating.
  • Increased heart rate/palpations.
  • Slight rise in blood pressure.
  • Tremors/jitters/nervousness.
  • Headaches.
  • Nausea.
  • Irritability.
  • Difficulty sleeping.
  • Dry mouth/increased thirst.
  • Slower urine flow.

If you experience any unpleasant side effects use your common sense and either stop taking the stack or stick with a lower strength dose.

If you slowly increase the dose as suggested you may not experience any side effects. Many side effects will disappear after a few days.

After a few weeks the stimulant effect of the stack can subside as your body gets used to it. This can make the user feel “its stopped working”. However, this is not the case. The thermogenic (fat burning) effect continues long after the stimulant effect has worn off.

Is the EC stack safe?

For healthy individuals the stack is regarded as safe as any other drug. That is to say, any drug (Alcohol, Paracetamol etc) can be harmful if it is abused or taken in very large quantities at once.

However, there are certain people for who it may not be suitable.

The stack is not recommended if...

  • You have pre existing heart problems or high blood pressure.
  • You have a thyroid disease or are taking thyroid medication.
  • You have diabetes.
  • You are pregnant, breast feeding or trying for a baby.
  • You are a growing adolescent (under 20).
  • You suffer from anxiety, nervousness or insomnia.
  • You are taking medication containing Monamine Oxidase Inhibitor (MAOI). Drugs for depression and psychiatric/emotional conditions.
  • You have an enlarged prostrate (men).
  • You have narrow/closed angle glaucoma.
  • Your cholesterol level is high.
  • You are using other products that contain Ephedrine or high levels of Caffeine e.g cold remedies and energy drinks.
  • You are doing high intensity training or playing sport outside in the summer months - You may become overheated and dehydrated without realising.
Is Ephedrine illegal?

Ephedrine use is banned in sports such as athletics, football and boxing (at a professional level) as it is regarded as a performance enhancing drug. A lot of sports persons have failed doping tests because they took a cough or cold remedy which contained Ephedrine.

In most countries, including the UK, it is not illegal to posses Ephedrine in 8mg tablets for personal health use.

Why make your own stack?

You can buy ready made EC stacks but it is much better to make your own stack for the following reasons...

  • You can accurately control the strength of the dose and tailor it to your own personal tolerance level.

  • You know exactly what it is your taking and that the ingredients are genuine and pharmaceutical quality. (Many ready made stacks/slimming pills are made in unregulated, illegal laboratories and contain impurities or have no effective ingredients.)

  • It is less expensive than pre made stacks.

What are T5 and Stacker slimming pills?

The original T5 and Stacker slimming pills were simply ready made EC/ECA stacks. T5's and "Stackers" became very popular as the genuine pills were/are very effective.

However, people began to “trade on the name” and started selling diet pills called these or similar names though they were often not true EC/ECA stacks.

It is now very difficult to know whether you are buying an effective version or not and another reason why it's better to make your own stack.

(Note: Don't get T5's confused with the thyroid hormones T3 and T4. T5's have nothing to do with the thyroid, all they have in common is their name.)

Do doctors prescribe the stack?

Though this might sound like a conspiracy theory, when the fat loss benefits of the EC stack were discovered the findings were “shelved” by the pharmaceutical companies. As they were unable to patent these readily available ingredients they saw little profit could be made.

Instead companies continued to manufacture and promote more expensive weight loss drugs they owned the patents to and could in turn make more money from.

Therefore, despite many doctors being aware of its potential to treat obesity, the stack has never been commercially produced or approved by the relevant authorities in order for them to actually prescribe it.

The supplement was however embraced by the body building community. Participants of this sport often use the stack during a process known as "cutting". Cutting is when a weightlifter attempts to strip away body fat in order to reveal muscle structure and gain a lean, muscular, "ripped" physique.

Obviously, you don't need to be body builder. Anybody can experience the fat burning effect of the stack.

Another big advantage of the stack (and why it's so popular with the gym going fraternity) is that it burns fat yet preserves muscle.

Maintaining muscle mass obviously produces a more shapely, toned physique which many see as the ideal.

Trying to lose weight by intensive dieting (basically eating very little) puts the body in to "starvation mode” causing both fat and muscle to be lost.

Sample customer reviews (from suppliers's website)

Amazing, works like a dream! I've lost loads of fat off my stomach and my jaw line has become more defined.
Ephedrine and caffeine has helped me lose 18lb in weight so far. The tablets arrived quickly and well packaged. I will certainly use this product again.
Fast delivery, discrete packaging, good results - very impressed.
Gives me a real energy boost and a great sense of well being so I don't turn to food when I'm tired and I don't find an excuse not to go and exercise.
Absolutely THE best diet pill I have ever taken.
Makes you feel nice and warm and suppresses your appetite. If you are just beginning a new diet program but finding it hard to restrict your calories I would definitely recommend these to give you a good start.
Burns fat and gives you energy. I won't use any other product.
Does exactly what it says on the tin and the service and delivery is impeccable.
I have tried all sorts of fat burners but none come close to the effects I feel with Ephedrine. I have two small children so my quality of sleep suffers and I find it hard to get the energy to train. These tabs really give me the boost I need to stay focused.
Very effective. I lost a stone within 3 weeks. Definitely recommended.
Has really helped me to stop snacking during the day and gives me extra energy down the gym. Also, I was really impressed with the delivery, I placed my order on Monday afternoon from the UK and received my order by Thursday morning.
Used for couple of months and lost 2 stone. Unbelievable. It reduces your appetite totally. Guaranteed to lose weight with very little effort. Buy it and stick with it.
I've lost about 10 pounds in a month, my stomach is getting flat and the love handles have nearly disappeared. Highly recommended.
After 3 babies in 5 years and years of having that extra weight I lost 25lbs. I am 40 and the best I've ever looked and felt.
Gives you a great buzz for the gym or a run, and also perks you up during the day too in terms of your mood.
Can make you feel a bit weird initially, but nothing uncontrollable. I'm on 6 per day now and stacking with 200mg caffeine tabs and 300mg aspirin tabs, which makes them work even better.
I've bought numerous diet pills but always come back to the stack.
