ECA Stack: #1 Fat Burning Combo? My Experience & Results

The ECA Stack is a combination of Ephedrine, Caffeine, and Aspirin (ECA). When these ingredients are stacked together, they create a synergetic effect.

This stack is used to accelerate fat loss, it’s by far one of the strongest fat burning stacks you’ll find. 

The reason why it’s gotten so popular is simple, it works.

There are many fat burners out on the market that gives little to no results, but the ECA stack is on another level.

ECA Stack Alternative Supplement

Ephedrine is responsible for increasing metabolism and suppressing appetite. With a higher metabolism, you’ll be able to burn more calories throughout the day. It’s also great for preventing hunger cravings so that you stick to your diet.

Next, we have Caffeine, an ingredient you’ll find in a lot of fat burners. This stimulant helps enhance performance and energy. Better performance will help you burn through your calories faster.

Last we have Aspirin. It’s used for relieving pain but in this stack, it helps prolonge the effects of Ephedrine.

I’ve used this stack several times when you could still get it. These days, the best product on the market is Eliminate by Huge Nutrition. It’s the closest thing you will find to the real ECA stack.

ECA Stack Dosage Information

Let’s take a look at the most effective ECA Stack dosage for fat loss. First of all, it’s important to start out with a low dosage to assess tolerance.

Now, we know that the ECA Stack consists of Ephedrine, Caffeine, and Aspirin. This means you will be taking 3 different compounds 1 to 3 times per day.

Let’s take a look at a few dosage examples.

Starting out, it’s advised to start with dosing each compound just once per day. For example, 25mg Ephedrine, 200mg Caffeine, and 81mg Aspirin. If you are sensitive to stimulants you could even do half of everything just to try.

From here, you can gradually build up the dosage until you reach your sweet spot. For me, the sweet spot was about 50mg Ephedrine, 400mg Caffeine and 162mg of Aspirin split into 2 dosages throughout the day.

Do not take your last dosage several hours before going to bed. You will experience difficulty sleeping due to the high amount of stimulants.

You will also find a lot of people that leave out the Aspirin and just take the Ephedrine and Caffeine. I personally have always used the full stack, including Aspirin.

It is also important to know that you should not use this stack if you have any type of medical condition. 


Before we talk about the results, you should know that it’s also very important to have a proper diet and workout routine.

In order to lose weight, you need to be in a caloric deficit. The ECA Stack will help you burn more calories but if your diet isn’t in check, it’s not going to work.

With the ECA Stack, I’ve lost up to 12lbs of fat in just one month. When I first used it, I started realizing just how effective it was. It helps fight sweet cravings, keeps energy levels high, and burns more calories.

For comparison, Eliminate helped me lose 10lbs in one month but I felt more energetic. I experienced fewer side effects with it so It’s currently one of my favorite fat burners to lose weight fast.

Does ECA Stack Have Side Effects?

Yes, the ECA Stack does have side effects. It can be very dangerous if you don’t know what you are doing. If you do plan on running it, you have to be careful.

Potential side effects include headaches, heart palpitations, insomnia, elevated blood pressure, anxiety, and dizziness. These are just a few examples of the side effects associated with the use of the ECA Stack.

Of course, you should definitely not be stacking it with other stimulants. This means you should skip pre-workouts that contain caffeine and other sources.

This is why I suggest going with Eliminate by Huge Nutrition, it’s as potent as the original stack but it’s a lot safer.

Speaking from personal experience, it’s just as effective when it comes to burning fat and suppressing appetite.

ECA Stack For Sale

Unfortunately, there aren’t any vendors that have the ECA Stack for sale. This is mainly because of the main ingredient, Ephedrine cannot be sold in dietary supplements.

Luckily for us, there is a replacement for the ECA Stack. It took years for this product to be released onto the market but it works extremely well. 

I’m talking about Eliminate. It provides all the same benefits you get from the ECA stack but without the side effects. All ingredients in Eliminate work synergistically with each other, drastically speeding up fat loss.

Instead of searching for places that have the ECA Stack For Sale, stop wasting your time and grab a few bottles of Eliminate.

I’ve used it for several months now and it is extremely powerful. You’ll experience increased fat loss, suppressed appetite, and increased energy. It also functions as an appetite suppressant.

The Bottom Line

Unfortunately, it’s not possible to get the active ingredients in the ECA stack anymore.

It was a great way of speeding up the fat loss, mainly because it helped with suppressing appetite and increasing metabolism.

With that being said, it wasn’t entirely safe, and it could cause adverse side effects.

Nowadays, there’s a new product on the market called Eliminate that does the same thing. It speeds up fat loss and is known as the best thermogenic fat burner on the market.

We advise that you try it out to see how it works for you. It’s a lot safer yet equally effective due to the potent formula.
