Our verdict: (4.7 / 5)


When it comes to weight loss, we could all use a little help and that’s where fat burners come in.

Just like any other supplement, fat burners that claim to reduce the poundage are a dime a dozen.

There’s literally a fat burner in every little thing now. But, what we have here seeks to accomplish the weight loss mission and more.

It’s called Instant Knockout and right now, your reviewer is falling in love with the fist-shaped bottle.

With just about every site we visit recommending Instant Knockout, we figured we find out for ourselves if there’s truth to those recommendations.

Read our review to find out!

What Is Instant Knockout?

what is

Instant Knockout is designed for fighters, by actual fighters – the fat burner’s tested and endorsed by MMA pros and boxers.

This supplement solves a common problem for these athletes:

It’s smart formula that helps them shed the weight and get ripped without having to think about eating losing gains, energy, or stamina.

  • Synergistic look. Just looking at it makes us think the researchers were awesome.
  • Appetite suppression. Most fat burners balk at the thought of adding fiber. Instant Knockout doesn’t.
  • More than a fat burner. It has an added performance boost with a lot of caffeine.

In addition to what we stated, the company is proud to claim the following:

You now have the opportunity to look fighting fit, without being a slave to your appetite or starving yourself for weeks on end.

We took the latest research and originally developed our formula as a side project, to help MMA fighters and boxers quickly burn fat when they ‘simply had to’ meet a deadline.

It proved so successful and popular however, we decided to launch it.

How To Use It?

Take 1 capsule with a glass of water, 4 times per day:

  • FIRST: Immediately after waking up, before breakfast.
  • SECOND: In between breakfast and lunch.
  • THIRD: 1 hour after lunch.
  • FOURTH: 1 hour before dinner.

Take your last dose no later than 5 hours before going to bed.



Instant Knockout gets off to a great start with a clear label, showing dosages of all their ingredients.

Nothing to hide here, bro.

The basic vitamins and minerals that follow are solid; B6 and B12 help energy, and zinc supports testosterone.

Moving on, chromium picolinate is the right mineral form for blood sugar balance, appetite control and metabolism.

So what we’re saying is, these are all solid vitamins in their own right and could help with fat burning, but they’re not the main course.

Now let’s get to the good stuff:

Green Tea Extract

This is one of the most scientifically backed fat burning ingredient in existence.

Most take green tea as beverage, but science has since revealed its fat burning potential on top of some of the anti-cancer benefits we all know and love.

You can say countries that drink a lot of green tea aren’t really those with problems with obesity.

Green tea extract (GTE) has been shown in some studies to increase fat oxidation at rest and during exercise. However, these results have not been consistent. Overall, there are more studies that demonstrate positive effects on resting fat metabolism when GTE is ingested, both shorter term and longer term. There is less supporting evidence for the use of GTE during exercise. The interaction between GTE and exercise training is interesting and animal studies are generally supportive of additive or interactive effects of GTE on an exercise training program.


Cayenne promotes thermogenesis, triggers fat burning hormones, and possesses appetite suppressing properties.

It doesn’t surprise us that it burns fat; everyone who’s eaten spicy stuff know all too well what happens when cayenne enters their system.

These results indicate that red pepper increases diet-induced thermogenesis and lipid oxidation.


Popularly known as Konjac Root, glucomannan has become extremely popular in recent years due to it being labeled as a weight-loss fiber.

Here are some glucomannan effects:

  • It’s soluble fiber, so it absorbs water and swells to fill the stomach.
  • Helps reduce carb absorption, helping stabilize blood sugar
  • Helps promote satiation, making you feel fuller for longer than usual.

It seems to be added here to help you shred without feeling like you’re starving.

By helping you feel fuller, longer, glucomannan makes it easier to stick to your cutting-phase regimen.

Green Coffee Extract

Supplying active compounds called Chlorogenic Acids (CGA), Green Coffee Bean Extract (GCBE) is a rising name in fat burners.

It blocks absorption of glucose, and then regulates glucose release into the bloodstream.

This creates a 2x synergy for better blood sugar balance, suppressing appetite while minimizing fat storage.

GCBE also acts like caffeine in a sense that it helps energize you while also break down fat.


That 300 mg dose can knock anyone out. Out of nowhere, Instant Knockout supplies a massive 300 mg serving of caffeine.

Science has shown it to be one of the best fat-burners there is, with stimulating and energizing effects that optimize its metabolic boost with enhanced physical performance in the gym.

If you’re caffeine sensitive, this 300 mg dose might keep you way, way up as it’s easily the equivalent of 3 brewed cups of coffee. Make sure to take it as early in the day as possible and when you know your workout’s going to be tough.

Black Pepper Extract

Black Pepper is more than just a good spice. Like cayenne, it also exhibits some fat burning benefits but what we’re after here is the bioavailability boost i.e. it makes every mg count!

Formula Analysis

formula analysis

Instant Knockout literally knocks out the competition with its formula and fat burning synergy.

The cool bottle says it all: Instant Knockout will knock the fat right out of you.

What we love about the product is how it manages to keep things short, yet explosive. At the same time, the synergy for each ingredient is mutual amongst them.

  • Green tea + caffeine = Performance, increased fat oxidation, and metabolic boost
  • Cayenne + glucomannan = Sparks fat burning and promotes appetite suppression
  • Green coffee + glucomannan = Blocks carb absorption and balances blood sugar which leads to further appetite suppression.
  • Black pepper + everything else = Each ingredient is automatically made much more potent.

So what we’re saying is, Instant Knockout is already one of the best there is when it comes to traditional fat burning.

All the ingredients they have are either backed by science or have been used in previous successful workout formulas before.

The only thing we can nitpick right now is how Instant Knockout omitted the use of premium or standardized ingredients.

Green tea isn’t standardized to EGCG, Cayenne is not standardized to capsaicin, Green coffee is not standardized to CGA, and black pepper is just plain black pepper. These forms could’ve tripled this formula’s potency without changing dosages.

But you know, we don’t mind.

Perhaps if they did that, the cost of the formula would’ve skyrocketed so we get it and we won’t hate on it just because we didn’t see our favorites.


Instant Knockout burns fat, helps suppress appetite, and spikes your energy and alertness for top physical performance.

Instant Knockout optimizes the body for supercharged training and accelerated fat loss, with extra muscle support so your gains don’t waste away.

Side Effects

side effects

For the most part, Instant Knockout’s formula is well-tolerated, but not everyone has the gut for such high-performing ingredients.

The cayenne pepper in raw powder form is sometimes associated with sensations of heat in the body and the stomach.

And of course, that 300 mg caffeine dosage may carry typical stimulant side effects like irritability, jitters, aggression, etc.

Here are some side effects identified by some users:

  • Insomnia
  • Irritability
  • Headaches
  • Drowsiness

Is It A Scam?

It’s not a scam as far as our research tells us.

Instant Knockout Reviews & Complaints

customer review

Here are some of the reviews we found. Let’s begin with negative ones.

Ronni D. Weis:

I feel like this product works very well. The problem I have with it is that my stomach hates it. It gives me horrible, horrible, gut rumbling gas. It is so uncomfortable. I’m noticing that I just have a sensitive stomach compared to a lot of other people. I thought it was the foods I was eating, so I tried cutting those out, but nothing changed. I cut the pills out and my stomach felt normal again. I just started taking them again after not taking them for about 5 days and it’s right back to painful gas again. This sucks cause I normally would never spend that much on myself and now I have a bunch of pills left that I can’t take. Oh well, like I said, they do work and definitely help melt the fat off. They also have incredible customer service. I enjoyed my transaction with them.

Nathan Smock:

I am about 10 days into using it. I have not noticed a huge difference in my weight loss. I have been working out about 3-4 times a week and eating pretty clean with the exception of a few adult beverages. I am going to continue utilizing and update my results. I do not get overly jittery or feel like I’m coming down when the product is wearing off. I am very sensitive to caffeine so that is always a big concern of mine. I have also tried many thermos on the market and so far like the blend of Instant Knockout but have not yet seen overwhelming results.

There were some gems, though, and these came from verified purchases.

Dan Mack:

I ordered Instant knockout a little hesitantly, after trying various fat burners previously which all promised fantastic results immediately but rarely work. I found the price was not overly excessive, especially for a months supply and I was sold on the testimonials from professional athletes and MMA fighters.

Initially not expecting much, I started on day one with my morning pill just before breakfast. Within ten minutes I felt full without taking a bite, naturally I was a little surprised as I did not expect the appetite suppression to take effect so quickly.

I continued throughout the course, sticking strictly to my diet and consuming the four pills daily. I have since started the same plan again to really pin down the difference on and off Instant Knockout, there is clearly a big difference and my most recent eight week plan has been much tougher without the appetite suppression.

All in all I would highly recommend instant knockout to anyone struggling to stick to a plan, as much as discipline is important a well engineered supplement makes a world of a difference.

Maz Dela Cerna:

I decided to try instant knockout after trying several other fat burners and after tons of research, I took the leap. Boy am I glad I did!

I will admit the first couple of days I was on such a high it was hard to sleep. I eventually got used to it and continued with my weight training. I eat pretty well so i really didnt change my diet.

I had increased energy, stopped eating out of boredom and felt so much stronger at the gym. I was on fire!

I tried it for 3 months and bought another 3 months worth. Even after the first 2 weeks on instant knockout I saw results. I was in awe!

If you are contemplating on trying it out I highly recommend it. Instant knockout has hekped me kickstart my journey and I am now a bikini competitor. I camt believe I was once 25kg heavier and now able to be on stage!

Thank you Instant knockout for bringing out this product. You have really assisted me in reaching my goals.


Upon starting first month of Instant Knockout, I immediately felt a difference in metabolic rate. The steady supply of caffeine in each pill kept me energized and more focused.

The results seen from Instant Knockout, while mixed with proper diet and training is amazing. I’ve tried a few other fat burners and none seemed to work as well as Instant Knockout.

In a single month I went from 187 pounds down to 179 while strength training. I purchased a 4 month supply of instant knockout and I’m excited to see what results I will have in the future.

I am currently halfway through my second month. In my opinion, Instant Knockout is hands down the best fat burning supplement on the market right now and I would recommend it to anyone.

Pros & Cons


  • Potent burn stack. Green tea + glucomannan+cayenne = super hot
  • Simple and spicy. Not too many, not too few ingredients.
  • Smart formula design. Scorches fat as well as boosts performance in all angles.
  • Synergy. The combination of some ingredients boosts their potency.
  • Made for fighters. That bottle says it all.
  • Transparent label. Real fighters don’t need to hide anything.
  • Great fanbase. We barely see any bad reviews.


  • Basic ingredients. Good, but could’ve been better.
  • Weak B Vitamins & Zinc. I mean, vitamins are pretty cheap to begin with.

Final Words

Here’s the thing with fat burners:

They’re not meant to be too complicated or require difficult serving instructions. We’re athletes in the making, the more time we spend outside the gym, the less time we spend burning the extra fat off.

Instant Knockout wants us to forget about all the complicated formulas and instructions and focus on one thing: weight loss.

Instant Knockout has outdone itself in many aspects.

It attacks fat from many angles, prevents the sensation of starvation, all the while keeping everything short and simple for the busy weightlifter.

For what it lacked in ingredient brands and standardizations it more than made up with synergy, decent dosing, and scientific backing.
