What Is Instant Knockout?

Claiming to be a 100 percent natural fat burner with clinically proven and thoroughly researched formula with plant-based ingredients, Instant Knockout is a shredding supplement that aims to achieve three things: Improving your metabolism, reducing how hungry you get, and increasing the amount of energy you’ll have in a day. Originally, the formula was designed to help professional MMA fighters cut weight before weigh-in day, but now it’s available for anyone seeking to further how much fat their body can burn while holding on to the muscle.

If you’re a serious athlete looking to add a little kick to his fitness routine or just have extra holiday fat to cut while you lift, Instant Knockout offers the chance to get a fighting physique – a body you can take great pride in as you look good without a shirt on. When it comes right down to it, isn’t looking good naked every guys’ dream?

Instant Knockout not only claims to help achieve this, but you can still burn fat even without a strict fitness routine. Seems to good to be true? We have researched Instant Knockout extensively to bring you a review you can trust instead of buying blindly. Read on to see whether Instant Knockout’s claims are true.



Developed by the London-based Roar Ambition, Instant Knockout was designed to give its users power without compromise; your goal is to cut fat and build muscle, not simply shave numbers away from the scale. The supplement isn’t just for those who want to fight professionally; it’s to help anyone who wants to get rid of unsightly extra fat without taking medications that use side-effect-inducing chemicals.

Specifically, Instant Knockout was made to help professional MMA fighters and professional boxers. When a fight has been scheduled, it is important for both fighters to shed enough excess fat without compromising their hard-earned strength gains so that they will qualify when they weigh in. These guys need a good, fast way to burn, and typical everyday methods aren’t going to do it, so Instant Knockout was born.


How Instant Knockout Works?

As previously stated, Instant Knockout was first meant to help professional MMA fighters and boxers meet their weigh-in requirements by getting them ripped in a short period of time. It should come as no surprise that the fat burning supplement works to improve muscle definition and assists those who want extreme conditioning. In fact, bodybuilders often use Instant Knockout while they’re cutting following a bulk period.

Instant Knockout works by improving your metabolism, giving it the energy it needs to burn fat more effectively without extra work. Though it may not be required, it’s still a good idea to use your excess energy at the gym to help further result improvement.


Ingredients of Instant Knockout

According to the official website for Instant Knockout, the formula has just a handful of ingredients, all of which are natural, plant-based and include both vitamins and minerals. Most of the ingredients are proven to assist with slimming one’s physique, and all of them are completely safe.

The current list of ingredients includes:

  • Green tea extract
  • Green coffee bean extract
  • Vitamin B6
  • Vitamin B12
  • Chromium
  • Cayenne powder
  • Caffeine

While there have been few studies done to specifically research the effect each of these on burning away extra fat, there have been none that suggest any ingredient is unsafe or ineffective. This shouldn’t be taken to mean that the ingredients can’t help you lose belly fat – but no one ingredient taken on its own will probably do the job without effort, which makes the Instant Knockout formula important.

Not only this, but by including a large amount of dietary fiber through the use of glucomannan, you’ll start to feel full more quickly, avoiding overeating and helping with caloric intake. If you begin the regime, it’s a good idea not to take it on a regular basis for over four months as excess fiber can have some issues over a long period of time.

Other than this, all of the ingredients in Instant Knockout are considered to be safe when taken in the recommended doses. Of course, everyone’s body is different from one another, so you may have a different reaction, but it’s unlikely to cause any issues. Again, there are few substantial studies presented about the efficiency of the ingredients, but this doesn’t mean that they don’t work.

The only questionable ingredient is green coffee bean extract as it’s been tested often for fat burning properties. The conclusion of such studies have generally been uncertain, and not all test subjects were human. While it’s a safe ingredient to consume, we wonder if Instant Knockout would be the same product if the ingredient were left out.



Now to the part you’ve been waiting for: What kind of advantages does Instant Knockout bring? The most sought after benefit of the supplement is probably that it helps you keep your lean muscle while shredding away the extra fat. Other far burners typically just promote basic weight loss, but Instant Knockout seeks to improve your muscle definition – not the number on the scale.

There is a big difference between taking a weight loss pill and an actual fat burner; it’s not just about what the scale says – we need to consider how we look. That’s the big benefit of Instant Knockout; you can keep that lean muscle and potentially even gain more.

The expected benefits of Instant Knockout include:

  • Improvement of energy;
  • Loss of fat while keeping and perhaps building more lean muscle;
  • Better metabolism as your body’s natural metabolic rate increases;
  • Limits appetite so that you do not consume more calories than is needed to keep muscle and eliminate fat;
  • Gives you much more energy that can be sustained during hard workouts.



According to the manufacturer’s website, the ingredients are responsible for making such a powerful supplement. Using carefully researched and chosen energy-boosting products, Instant Knockout is made in CGMP and FDA certified facilities; that means you can be sure all bottles are made to the highest quality.



Don’t just take our word for it, of course. It’s a good idea to check out some of the testimonials of real customers that have tried Instant Knockout for themselves.

Fred, 27, Florida:

I’ve tried so many other fat burners before, and while some of them helped, they were all too slow. After some hesitant thought, I finally decided to try out Instant Knockout – and I was just blown away. With such newfound energy, I could focus on my muscle definition and get myself down to a lean 210 to prepare me for the bulking cycle.

Alan, 42, California:

After a month and a half on Instant Knockout, I took some pictures to compare my physique. I’m really pleased with the result of my muscles, which I was able to keep while losing fat. I’d happily recommend the product to any other guy who’s sick of cardio and wants to cut fat.

Kyle, 22, New York:

After enjoying myself all summer, I realized I had let myself get a little out of control; I didn’t have much muscle, and all this fat was lingering in my gut. I checked high and low for a good fat burner and realized Instant Knockout was what I was looking for. Now I’ve been on it for three months and I can safely say I’ve lost most of my belly fat and gained a fair amount of muscle from weight training.

Edgar, 50, Florida:

As an older guy, I used to believe that I had missed my prime time and wasn’t meant to get fit anymore. A friend suggested I try a fat burner, and I decided to give Instant Knockout a try. I’m so glad I did! I’ve lost tons of fat without having to undergo a strenuous workout every day.

According to the manufacturer’s website, you can get submit your own Instant Knockout success stories. In the event that the company wants to display your photos on the website, you’ll even get paid for the result. All you must do is:

  • Use Instant Knockout according to manufacturer instructions for over a month;
  • Maintain a workout schedule for best results;
  • Send a clear before and after photo that shows your progress;
  • Provide a brief testimonial that includes whether you are a professional bodybuilder or if you’re simply someone looking to improve his body;
  • Provide, if possible, a brief 60-second video that explains how well you liked using Instant Knockout;
  • Ensure that the photos are only of you – you will not be paid for false results or photos of someone else.


Money-back Guarantee

Like any product, you’ll get what you pay for. The science of Instant Knockout has several fat-burning ingredients to its advantage; compared to any competing product, it’s hard to see why anyone would go with another product. Most others use proprietary formulas that don’t immediately show how much of what ingredient was used.

You want a quality product with great ingredients delivered in a safe dosage for the best results. Instant Knockout is not made with a proprietary formula, which means you know how much of what ingredient is used. Keep that in mind before going with an ineffective product.

Currently, the only way to obtain Instant Knockout is through the manufacturer’s website. It can be a little pricey, but many customers agree that it is a quality product that you’ll enjoy upon trying. This is much better than getting a product that costs half as much but doesn’t actually work at all.

By ordering Instant Knockout today, you’ll be able to try it for 90 days. If it fails to work like the company claims, you’ll just need to send it back to get a refund. Simply put, if you aren’t satisfied, the company wants to help make it better.

According to the terms and conditions of the website, however, it is important to note that this money-back guarantee only qualifies for those who have purchased at least a three-month supply of the product. Not only this, but there are a few other requirements as well:

  • You must have tried Instant Knockout for the complete 90-day period as the packaging instructs you to;
  • You must have tried some regular weight lifting exercises;
  • You must have eaten a healthy diet.

As long as you meet these requirements, then you can request a refund by submitting:

  • Your name, address and order number;
  • All unused and used items previously sent to you;
  • A written description of your diet plan and workout;
  • The product itself sent with signature required;



The manufacturer has set up distribution centers throughout the United Kingdom and the United States, though they are willing to ship anywhere in the world. That means that no matter where you live, you should have no problem being able to purchase Instant Knockout and have it sent to you; in fact, they even will ship to an APO address if you are in the military. The orders are always sent fast, with the exception of weekends, and include tracking.

The 90-day money back guarantee is another saving grace; if you haven’t seen results in the first three months of trying Instant Knockout, they’ll give you a refund less the shipping. Most supplement companies don’t make these kinds of guarantees, perhaps citing a lack of confidence.


Customer Support

There is no phone number currently available for customer support. However, there is an email address and a form on the manufacturer’s website.


Safe & Secure Checkout

The manufacturer website is well secured using a secure socket layer. From the moment you select a product, the website automatically provides a secure environment before redirecting you to secure payment pages. You never need to provide financial information on an unsecured website.

All you will need to do is add the product to your cart by clicking the appropriate button when making your decision. You will have the option to select a one month bottle, a two month supply or other options before adding it to your cart. With the product in your cart, you may proceed to the checkout portion.

Instant Knockout is only available through the manufacturer website. As an online product, it is not possible to go to the store and find the product on the shelves. All orders will be processed through the appropriate distribution center as there are no physical facilities to display or sell products. Because of this, the company seeks to offer very fast delivery that processes orders through the mail, meaning it is also not possible to pick up your order even if you happen to live close to a distribution center.


Instant Knockout Pricing

As of writing, it is not possible to purchase the Instant Knockout product anywhere else except for the official website. You may purchase a one-month supply for $59, though there are sometimes promotions such as buying 3 bottles to get 1 for free; that deal would be backed by the 90-day guarantee.

When asked whether Instant Knockout would ever be sold at a physical retail location, it seemed the owner was not interested in this for the near future. This is not a surprise; most companies that put products on the shelves end up with a big profit loss at the end of the day.

Every bottle of Instant Knockout has 120 500mg capsules and can be purchased in the following quantities:

  • 1 bottle: $59 for the month supply, plus $7.95 shipping and handling – there are faster options available, but they’ll cost more;
  • 2 bottles: $118 for the two month supply and free shipping and handling to the UK and US;
  • Ultimate Shredding Stack: $185 and free worldwide shipping for three bottles of Instant Knockout along with a t-shirt;

As previously stated, though Instant Knockout is backed by a 90-day refund policy, it would not be available if you had only purchased one or two bottles. This is not an arbitrary limitation; this is because the manufacturer has a specific recommendation for the product, which requires that you follow the regimen for 90 days first.

You must take the product for at least 90 days according to the packaging, eat a diet of rich and healthy calories and perform typical weight lifting exercises on a regular basis. When returning the bottles, make sure that you list your name and order number so that the company knows that you are the one who returned the product. To ensure safe delivery, be sure to require a signature upon delivery.

Instant Knockout

Summary: Simply put, Instant Knockout is an excellent formula made to help shred body fat while improving overall energy levels.

At the end of the day, it’s a clean fat burner compared to others, not unlike how natural gas can defeat diesel.
