People often turn to fad diets, weird exercise routines, and even steroids to lose weight, but one thing reigns king to them all: the ECA stack.
While it certainly isn’t as powerful as thermogenics such as DNP (an illegal steroid/fat burner), this stack is still considered to be relatively safe.
…but, the question still remains: does the ECA stack actually work, or is it just another fad supplement that will sell you empty promises?
The truth is that it does. This so-called “ECA Stack,” short for Ephedrine, Caffeine, and Aspirin, has been used for years due to its ease of acquirement and high effectiveness.
This isn’t something you want to mess around with, though—many of these substances should not be consumed if you’re under 18.
That being said, if you’re looking for a magic bullet to push your fat loss into overdrive, look no further than this stack here.
In this quick, step-by-step guide, I’m going to explain what an ECA stack is, exactly how it works, and exactly how to take it to shred more fat.
As said before, an ECA stack is simply a combination of ephedrine, caffeine, and aspirin. That’s it—nothing more, nothing less.
The whole idea behind this stack is that it speeds up your metabolism and suppresses your appetite, thus making it easier for you to shred body fat.
The ECA stack combines three readily available substances, that when taken together, will help you shred fat off like it’s nothing:
All three ingredients work in conjunction with one another, to increase your metabolic rate, and thus help you burn calories faster.
In fact, in a study conducted at Harvard Medical School, researchers found that it literally burned 246% more fat than placebo:
“Overall weight loss over 8 weeks was 2.2kg for ECA vs. 0.7 kg for placebo (p < 0.05). 8 of 13 placebo subjects returned 5 months later and received ECA in an unblinded crossover. After 8 weeks, mean weight loss with ECA was 3.2 kg vs 1.3 kg for placebo (p = 0.036).”
In other words, people who took the “Ephedrine, Caffeine, Aspirin,” stack lost more than twice as much weight as people who didn’t take it.
The caffeine is typically consumed in the form of caffeine pills, which can be purchased on Amazon or at any run of the mill general store.
Aspirin is also easy to attain, and is available at most pharmacies. The only ingredient that’s going to take some work is the ephedrine.
While it can be purchased online, the legality of this is questionable. Your best bet is to grab an over the counter medicine called “Bronkaid,” which is typically prescribed for Asthma, but has 25mg of ephedrine per pill.
Bronkaid can also be obtained pretty easily at any major pharmacy, although they may ask for your ID.
Once you’ve got yourself some caffeine pills, a bottle of aspirin, and some Bronkaid tablets, it’s time to get down to work.
I recommend you assess your tolerance first by taking smaller doses at first, and then working your way up to the full stack dosage.
The following ECA stack is typically taken 3x per day:
For those of you who are sensitive to stimulants, simply one dose of this stack will have you wired for an entire day.
If this is the case, please take your time in scaling up to three doses a day, because while the ECA stack is generally considered safe, anything is subject to harm you when abused or used improperly.
When taking this stack it’s important that you consume lots of water, and take at least 1-2 days off a week to let your CNS recover.
It’s recommended that you drink a gallon a day, especially if you’re also taking supplements like creatine and in conjunction with the ECA stack.
The Ephedrine part of the ECA stack is what really gives it the oomph that it’s known for. Ephedrine is by far a stronger stimulant than caffeine.
…and while it’s not as strong as other stimulants like Gorilla Mind Rush, it’s still pretty damn strong. So, you should use it with caution.
Like I said, you can’t get it over the counter… you have to request some Bronkaid from a local pharmacist, and then buy a couple packs.
You take one tablet of Bronkaid per dose of this stack, which equates to roughly 25mg of Ephedrine.
This speeds up your metabolism and acts as a beta agonist, which will pump out fat-burning, energy-increasing hormones in your body.
Some people prefer to take caffeine pills, but personally I’d rather just drink coffee with my ECA stack. Not only does coffee have a ton of benefits, but if you get the right stuff, it tastes great as well.
Caffeine is an integral part of this stack, because it’s known for suppressing appetite and also increasing metabolism. This will help you get a six pack faster than if you just used Aspirin and Ephedrine alone.
Coffee by itself has a ton of benefits, but when you combine it with Ephedrine (from Bronkaid tablets) for the ECA stack, you’ll be shredding fat faster than you can say “six pack abs.”
Aspirin isn’t really a fat-burning agent by itself, but it’s taken along with the ECA stack in order to prolong the effects of caffeine and Ephedrine.
When you take the “EC” part of the ECA stack, you’re taking Ephedrine and caffeine which will increase norepinephrine in your bloodstream, a hormone that is associated with increasing metabolism.
Taking aspirin alongside this, inhibits the decrease of this hormone. In other words, it basically just makes the stack last longer, by extent, far more effective.
The ECA stack has a ton of benefits, with the biggest one being weight loss. It’s no secret that most people take it to lose weight and cut fat.
That being said, there’s also some other benefits to this stack, such as using it for energy, and/or using it for studying or focus.
Here are some common ECA Stack Benefits:
It’s similar in effect and feeling to Adderall, which makes sense, since both Adderall and the ECA stack increase norepinephrine in your body.
Like I said, the biggest benefit of the ECA stack is that it helps users cut weight fast. While it isn’t as effective as SARMs, it’s still pretty great.
It can be especially helpful if you’re trying to cut off those last 5-10 pounds of fat before your six pack abs start to show.
The ECA stack can help give you that extra edge you need and want in order to lose those last few pounds of fat… so I highly urge you to try it.
Another added benefit of the ECA stack is that you’ll have a ton of energy while you’re on it. This makes sense, since obviously the ECA stack has Ephedrine and caffeine, two powerful stimulants.
The great thing about the ECA stack is that once you find your optimal dosage, you can just keep re-taking it for endless energy throughout the day.
There will be a small crash, but if you know how to time your dosage, you can time it so that you crash right around bed time, and then it’s easy for you to fall asleep at night.
For extra energy, you can also take it with some of the best pre workouts that I’ve reviewed previously. This is not for the faint of heart, though.
If you’re a student, you might find that the ECA stack works wonders for your mental clarity and focus. It sure makes studying easier.
That being said, I can’t recommend this stack for anyone under 18 years old. Not that it’s bad for you, but I’m not a doctor, so I don’t want some kid with a heart condition getting a heart attack or some shit.
I took the ECA stack when I was 16, and I turned out fine, but again, I’d recommend you wait until college to use the ECA stack for studying.
Another added benefit of the ECA stack, is that since it’s an appetite suppressant, it’s easier to do intermittent fasting while on it.
Intermittent fasting has a ton of benefits for fat loss, muscle gain, and overall health, so this is definitely a plus.
While you don’t have to fast while you’re on the ECA stack, I definitely recommend it—especially if you’re trying to lose weight.
Not only will the ECA stack help you shred fat, but the added benefits of intermittent fasting will add up faster than you can count.
The first time I tried an ECA stack was when I was 19 years old in college.
I’d been working out for a while and had a really solid base of muscle, but wasn’t quite as shredded as I wanted to be.
I decided to take the advice of a fitness forum that I regularly visited at the time, and get on an ECA stack.
I’ve got to be honest here, it was incredible. I was so laser focused on absolutely everything I did, from homework to socializing, and it gave me a great boost of energy throughout the day.
In fact, I’d even go so far as to say that the ECA stack can be consider a nootropic, or a “smart drug” in layman’s terms.
Not to mention the fact that it really helped me lose those last few pounds of fat, albeit I was also eating healthy and lifting weights.
If you’re looking for a “quick fix,” the ECA stack is your best friend. While it certainly won’t cause you to lose 15 pounds of fat overnight, it will definitely make dieting and shredding fat a hell of a lot easier.
Be careful combining this stack with other supplements, though, particularly other stimulants, like caffeine or Adderall.
Any pre-workouts should be monitored carefully, as you can easily hit very high doses of caffeine if you’re combining this stack with pre-workouts each day.
I get a lot of questions about how to take the ECA stack, the best dosage, when to take it, the side effects, and so on, and so forth.
So, I’ve compiled a list of the most commonly asked questions about the ECA stack. If you think I left anything out, just comment down below!
It depends on the dosage you take, and your tolerance to stimulants, but generally speaking the ECA stack will last about 6 hours.
If you continually re-dose throughout the day, which most people typically do, you can expect it to last pretty much until you go to bed.
Some people might end up taking more, but generally speaking, the best ratio is 25mg of Ephedrine, 200mg of Caffeine, and 81mg of Aspirin.
I don’t recommend you take anymore than this, because it’s already going to be really powerful. You always want to assess your tolerance first.
Personally, I have taken the ECA stack before my workout, and ended up just fine. If you have a heart condition, you should avoid this, though.
If you have an extremely high tolerance to stimulants, you can consider combining the ECA stack with a pre-workout, like Nitraflex.
For most beginners however, I do NOT recommend combining the ECA stack with your pre-workout, because it will be way too strong.
The dosage for bodybuilders is the same for regular people: 25mg of Ephedrine, 200mg of Caffeine, and 81mg of Aspirin to start.
If you find that you tolerate this dosage well, you can consider re-dosing up to three times per day. Anything more than this is too much, though.
Most users take their first ECA stack dosage in the morning, followed by another dose at lunch, and one more before dinner.
Be careful when taking the ECA stack too late, however. It’s very powerful, so can interfere with sleep if you take it within 8 hours of bedtime.
It’s recommended that you take the ECA stack first thing in the morning on an empty stomach. This way, it will hit you extra hard.
From here, if you feel good, you can re-dose every 4-6 hours up to two more times. Anything more than this and you risk some serious side effects.
There isn’t one. Most of the ECA stacks you see sold online are fake, because selling Ephedrine anywhere other than a pharmacy is illegal.
If you want to do the ECA stack, just buy the ingredients yourself at your local pharmacy. All you need is Bronkaid, caffeine, and aspirin.
Thankfully, yes. All of the ingredients you need for your ECA stack can be found at your local pharmacy for very cheap.
You may need to show your ID in order to purchase the Bronkaid, but the caffeine and aspirin are easy to get, and cost under $10 at Walmart.
Now that we’ve talked about the benefits, let’s take a look at some of the side effects of the Ephedrine, Caffeine, Aspirin stack.
Here are some common side effects for the ECA stack:
Most stimulants are going to share these side effects, but the good thing is that if you experience them, you can just take less.
You don’t need to take the full ECA stack dosage if it does give you side effects. Rather than re-dosing twice each day, you can just re-dose once, or only take one dose in the morning.
All in all, the ECA side effects aren’t really that bad. They’re no worse than the side effects of drinking too much coffee, to be honest.
In fact, the side effects of prohormones, which are technically more “legal” than this stack, are at least 100x worse. No joke.
I experienced a little bit of restlessness and jitteriness when I was on this stack, but it wasn’t bad—I got used to it in a few days.
Dieting and lifting weights certainly isn’t easy.
In fact, it can really be a struggle sometimes—but with that being said, nothing worth having in life is easy.
The feeling I get when I walk around at the beach with my shirt off, as girls stare me down like a piece of meat, is absolutely indescribable.
You can have that feeling too, if you’re willing to put in the work.
