How Did We Hear About Instant Knockout?
If you’ve ever been researching fat burners on the internet, you’ll know all about Instant Knockout by now. There are a lot of supplement websites out there, and many of them crown Instant Knockout as the best.
There are plenty of testimonials out there of people who have had success with Instant Knockout website, here’s some of the more notable ones that we have seen:
And here’s some results that we’ve seen for the women using Instant Knockout:
We were suspicious at first due to the amount of positive attention it has, and the overwhelming amount of testimonials. To know for sure we decided to buy a box for ourselves and run it for the full 3 months.
You can read my full results with before and after pictures, later in this review. But first, let’s look into who is actually makes Instant Knockout:
Who Makes Instant Knockout? – About Roar Ambition
Roar Ambition is a sports performance supplements company founded in the UK and has been running since 2014. When we started researching them for the purposes of this review, we were very impressed by what we found.
There are several things about Roar Ambition that stood out to us that we haven’t seen with much other supplement manufacturers. Here are just a few things that really stood out to us about them:
- Their business model
- Focus on quality
- Commitment to the health industry
- Customer Care & Shipping Logistics
Roar Ambition’s more interesting angles is their business model. Unlike most other supplement manufacturers, they refuse to sell their products through a third party.
You won’t be seeing Instant Knockout in the shops anytime soon, or ever. Roar Ambition only sell Instant Knockout from their product website (InstantKnockout.com).
Why do they do this? To keep costs down for their customers. The quality of ingredients in Instant Knockout is higher than most, and in doing so, it costs more to produce. Rather than cut in a middle-man like one of the major supplement stores, Instant Knockout is only sold directly from their website.
Their belief is that their product is strong enough that they don’t need another company like GNC, the Vitamin Shoppe or Bodybuilding.com to push their product for them. It sells itself, and we’re inclined to believe them.
The Quality of The Ingredients
As we’ve mentioned, the ingredient quality in Instant Knockout is high. Roar Ambition only manages a few products in their company, they don’t have a big range like most other manufacturers out there. This allows them to concentrate a lot more on each supplement to ensure the best results.
Instant Knockout is a prime example of this. We did the research and found that Instant Knockout has had it’s formula revised numerous times over the years. Roar Ambition constantly changes it to keep it up to date and a fierce competitor in the market.
The ingredients themselves are good too, the supplement itself is produced in cGMP and FDA approved facilities.
Roar Ambition’s Commitment to the Industry
What we found most impressive about Roar Ambition is their original reason for formulating Instant Knockout: it was originally made for MMA fighters.
Roar Ambition had no intention of selling the supplement to the public. At first it was designed with the sole intention of helping fighters to cut weight before a match. It had to be legal with their competition rules, safe, and effective.
It was met with a lot of success. Only after Instant Knockout was so well-received by the fighters that used it, did they decided to go public with the product and sell it worldwide.
Many fighters have used Instant Knockout, but the most notable user has to be Diego Sanchez of UFC fame:
He’s a very strong advocate of the fat burner and has talked about it regularly on social media:
Roar Ambition appeared to initially formulate Instant Knockout for performance, not profit. It’s this strategy that we think is one of the reasons why this supplement is so effective.
Customer Care and Shipping Practices
Despite not using a middle-man company to help sell their product, Roar Ambition doesn’t cut costs when it comes to their customers.
Here are just some of the benefits they offer with Instant Knockout:
- Discounts – Buying more than one box of Instant Knockout reduces the overall price
- Money Back Guarantee – Every 90 day supply is covered by a money-back guarantee
- Ships Worldwide – Roar Ambition ship globally and quickly from the USA and UK
- Fast Response Time – Their customer service team is available 24/7
What this shows us, is that Roar Ambition really believe in what they’re selling.
It’s the money back guarantee that we really like here. If you order the product, use it and don’t like it, you can send it back for a full refund. Here’s the promise from their website:
Roar Ambition do not offer coupons, or any other form of discounts apart from is available on their website from multi-box purchases. This is the only way you will be able to knock the price down.
Here are the discounts on multi-box purchases of Instant Knockout:
- 1 Month Supply (1 Box): $59.00 / £35.00 / €45.00 | $1.96 a day

As you can see, your best value for money at $1.54 a day is the ‘Ultimate Shredding Stack’.
My Instant Knockout Results: Before and After
I bought the Instant Knockout ‘Ultimate Shredded Stack’ directly from their website and used it for a period of 3 months. I took photos before and after to document my progress.
During this 3 month period I lost a total of 25 lbs of fat (roughly 11kg). I went from 180 lbs down to 155 lbs – and the main areas where I noticed the most difference was in my face, stomach, waist and back.
If it helps, I’m 5’11, which may give you a good reference point if you’re a similar height and weight.
Here are my results:
As you can see, I really benefited from using the product. My chest became more defined and I even lost the love handles around my lower back.
Here are the main benefits I experienced:
- Feel Better Each Day – I had more energy and motivation.
- Easier Gym Sessions – Despite eating less my workouts never felt like a struggle.
- Didn’t Need to Snack – Appetite suppressants helped me stop snacking through the week.
- Stronger Lifts – Even thought I lost weight, my actual lifts in the gym improved.
- Compliments – My friends and coworkers definitely noticed the difference.
One thing I didn’t realize until writing this review, was how much my posture changed during the process. The belly weight gave me a slouched posture, without it I’m much more upright and healthier.
How I got these results
Before we go further, this wasn’t just Instant Knockout that helped me get these results, I also did diet and exercise.
A lot people assume that fat burners allow them to take the easy road when it comes to fat loss. Fat burners can help make it easier, but they won’t do all the work for you.
Here are the main things I did when I started losing fat, I hope they’ll be of some use to you:
My fat loss approach:
- Took Instant Knockout 4 times a day – I took this fat burner 8am, 11am, 2pm and 5pm every day for 3 months.
- No Alcohol – I didn’t drink alcohol for the full 3 months. There’s a lot of hidden calories there.
- Lift Weights 3 times a week – I was pumping iron in the gym Mondays, Wednesdays and Fridays.
- Cardio twice a week – I did light cycling in the gym for an hour Tuesdays and Thursdays.
- OMAD (One Meal A Day) 5 days a week – I got all my recommended calories and nutrients in one meal each day Monday – Friday. There were no calories outside of that meal except water or green tea. The meal was heavy in steamed vegetables with some light protein and fats on the side.
- Cheated on Sundays – I could’ve lost the weight a lot quicker if I hadn’t snacked on weekends. I relaxed my eating habits on Saturdays and went really bad on Sundays. Sometimes you need that mental break from dieting.
I’ve tried a lot of these methods before, usually whenever I get out of shape. However, I’d never seen them work so effectively after they were combined with Instant Knockout.
Follow that, and keep an eye on your calories and you’ll definitely be on the right path.
Did I experience any side effects?
None. Instant Knockout was easy to take with a glass of water 4 times a day. The only thing I would say is to be aware of is the caffeine intake. Each capsule has around 75 mg of caffeine in it – which is the equivalent of a weak cup of coffee.
If you have a very sensitive tolerance to caffeine, you may want to lower the dosage or go with a different fat burner.
Will I use it again?
Definitely. Every now and again I let loose on my diet and bulk up – and when I do, I’m ordering another round of Instant Knockout.
I understand my training and diet played a part in this process, but I’ve never got into shape this quickly. It’s a great before and after for Instant Knockout.
Why I think Instant Knockout is Better Than Other Fat Burners
What is it about Instant Knockout itself that makes it so effective?
There are two things in particular:
- The Ingredients: They’re well researched, effectively-dosed and of a high quality.
- Multiple Servings: With 4 servings a day, Instant Knockout keeps your body in constant fat burning mode all day.
Although it sounds simple, you’d be surprised how many other manufacturers choose to not focus on these areas in the name of profit.
Why don’t other manufacturers do the same?
Money, mainly. It’s a lot cheaper for a company to offer their customers, weaker less effective ingredients. This is because without the sales to back up their claims, those types of ingredients are a lot easier to get a hold of as there is less demand in the market.
If you want effective, study backed ingredients that are of a high quality, you need to be prepared to pay the big money, and Roar Ambition are.
The same goes for the servings. With a single serving a day, you’re only going to get a few hours of benefit – however, it’s a lot cheaper to produce. A manufacturer only has to pay for 30 capsules for a month’s supply.
Instant Knockout on the other hand contains 120 capsules per month. This is so you can take 4 capsules spaced out throughout the day to keep your body constantly reaping the benefits.
Instant Knockout Ingredients: Our Research
Stepping away from the personal results I’ve had with Instant Knockout, let’s take a look at the science. The reason Instant Knockout works so well is because of the ingredients. They’re well-researched and seen in studies to be effective.
Let’s take a look at them:
The ingredients that stand out in this blend to us are the:
- Green Tea – Thermogenic / Focus Booster
- Green Coffee Bean – Thermogenic
- Cayenne Pepper – Thermogenic / Appetite Suppressant
- Glucomannan – Appetite Suppressant
- Caffeine – Metabolism Booster / Energy Booster
Below, I’m going to explain why they work so well.
Green Tea: Thermogenic & Improves Focus
Green Tea is our favorite fat burning ingredient in supplements – mainly because there’s so many studies out there that show that it works.
It’s successful because it contains a specific form of antioxidant known as catechins. These catechins, when absorbed by your body help to reduce your body’s suppression on a hormone known as norepinephrine.
Norepinephrine is your body’s fat burning hormone. The more of this you have in your system, the more fat you’ll burn throughout the day.
Research shows that an average cup of green tea burns the average of 5.7 grams of body fat (source).
Green Tea also contains L-Theanine. L-Theanine is an amino acid which has links to improving your overall attention span (source).
Green Coffee Bean: Thermogenic
This is another good choice in Instant Knockout. Green Coffee is essentially coffee bean that haven’t been roasted. This is why they’re green. Not only that, they also contain a high amount of Chlorogenic Acid which is why it works as a thermogenic.
Chlorogenic Acid is a component in Green Coffee Bean that helps to lower the glucose levels in your liver. Your body uses this glucose for energy, without it, your body has to turn to your stored fat to keep giving you energy.
Over a 12 week study, obese participants who took chlorogenic acid enriched instant coffee experienced an average fat loss of 5.4 kg (or 12 lbs) (source).
Cayenne Pepper: Thermogenic & Appetite Suppressant
One of the smarter choices in Instant Knockout is the Cayenne Pepper. Cayenne Pepper is a hot chili that is used in this supplement for fat loss because it contains capsaicin.
Capsaicin is the component that gives the chili its heat. Once your body absorbs the nutrient it can raise your body’s temperature. In doing so, your body has to start a cooling process to regulate itself. This uses more energy than you would normally, the result is that you burn more calories, and by extension: fat.
Studies show that supplementing Capsaicin can help increase your overall energy expenditure throughout the day (source) which boosts your overall calorie output.
However, burning fat isn’t the only benefit, studies also show that it can help suppress your appetite and help you feel fuller for longer (source).
Glucomannan: Appetite Suppressant
This is the largest serving of any ingredient in Instant Knockout – 1800 mg of Glucomannan per daily serving. There’s good reason for this too, you need a lot of it.
Why? Because Glucomannan is a fibrous complex that comes from the Konjac Root. After you consume it, the complex swells in your stomach. The advantage of this is that it helps you to feel fuller for longer, reducing the temptation to snack throughout the day.
Studies show that supplementing Glucomannan is effective for weight loss with the average subject losing 5.5 lbs over a 8 week period without changing diet or exercise habits (source).
Caffeine: Energy & Metabolism Booster
You already know this one. Caffeine is a stimulant that is in most energy drinks and of course, coffee. Studies show it is good for:
Here’s the main way caffeine works: in your brain there’s a compound known as adenosine. Adenosine binds to nerve cells in your brain and slows them down to encourage you to rest, and eventually sleep.
These nerve cells can’t tell the difference between caffeine and adenosine, so when it’s available they’ll bind to caffeine instead, which locks out adenosine. This speeds up your cells and keeps you more active, and improves your metabolism and energy levels.
Instant Knockout’s Servings: 4 a Day VS 1 a Day
Another interesting factor about Instant Knockout is the serving amount. There are four servings a day. This has both positive and negative aspects to it.
From a positive perspective, it’s great for fat loss. You are giving yourself a constant top up of the nutrients your body can use to burn more fat. However, from a more negative view, you have to keep on top of the dosages.
It is annoying at first, but you do get used to it. I started by setting myself alarms at 8am, 11am, 2pm and 5pm. This helped me keep on top of it, and then after the first week I didn’t need to remind myself. Aside from that there’s no real issues with it.
This is a better way to take supplements rather than one serving a day because the effects last a lot longer. With one serving a day, you’re only going to be getting the benefits for just a few hours.
What are people saying about Instant Knockout?
The reviews online for Instant Knockout (including this one) are mostly positive. A lot of people like it and are getting the benefits.
One video that stuck out to us in particular was a man called Jeremy:
If the video isn’t working (or if you don’t have time) Jeremy experienced the following:
- Lost 10 lbs without changing his exercise or diet routine
- No side effects (but has had side effects from other fat burners in the past)
- Didn’t feel the need to snack throughout the day
- Claims to have lost 3% body fat from taking it
He seems genuine enough, although he’s clearly had a physique similar to that before Instant Knockout and knows how to workout and diet effectively. To me it appears that the fat burner probably gave him that extra edge to lose the additional pounds on top of his regular routine.
There are also plenty of testimonials over on the Instant Knockout website. You can see them all over on their testimonials section.
Is Instant Knockout Safe For Everyone to Use?
Fat burners are not safe for everyone. If you have any pre-existing conditions, or allergies, you should always check with your doctor before using a new supplement.
You should also note the caffeine level is 300mg a day. As we’ve mentioned, this breaks down to 75mg (or a weak cup of coffee) every few hours.
Can Women Use Instant Knockout?
There are plenty of women out there using Instant Knockout.
Although we do say it is the best fat burner for men, it is safe for women to use. If you’re a woman and engaging in regular exercise, dieting right and have the all-clear from your doctor, you shouldn’t have a problem using this supplement.
Here’s some of the before and afters that we’ve seen from women using Instant Knockout:
If you’re interested in what Instant Knockout have to say about women using their product, they have a section for it on their website.

Post-Review Questions about Instant Knockout
These are the questions I have been asked the most regarding my review of Instant Knockout and what other questions I have seen asked online.
Is it vegan?
The ingredients are, but the capsules are gelatin. There is a workaround to this, if your comfortable with it, we suggest popping open the capsules and dissolving the powder in water and drinking it.
Another option is to open the capsule and toss the powder into your mouth and wash it down with water.
Is it legal?
Yes. All the ingredients in Instant Knockout are completely legal and natural. This includes sporting competitions. You won’t fail any tests from taking this supplement.
How long does it take to work?
For the energy effects and appetite suppression – it’ll start working the same day. To see physical results depends on a lot of factors, mainly your diet and exercise regimen.
I started to notice weight loss of a few pounds within the first week.
Can I take it on an empty stomach?
Yes you can. There’s nothing in here that will irritate and empty stomach. I took it while intermittent fasting (or more specifically doing OMAD / One Meal a Day) and noticed no problems.
Is there a monthly subscription / re-billing service?
No there isn’t. They’re not going to charge you for anything else aside from your initial order.
Where is it made?
It is made in FDA and cGMP approved facilities in both the USA and UK.
Can you stack it with other supplements?
You can, but it depends. This is because Instant Knockout contains caffeine.
Testosterone boosters, Nootropics and other supplement that doesn’t have caffeine in them should be fine to use. Always check with your doctor or medical professional first though.
Can you take it without exercise?
You can, but you may not get much of a benefit. If you want to see results, you should be dieting and exercising alongside this supplement.
Will it ever be available on Amazon or Ebay?
Not by Roar Ambition. They claim they never will sell on Amazon or Ebay, and that any vendors of that platform may be selling fakes and they do not take responsibility for any purchases made over there.
How long does it take to arrive?
It varies from country to country, you can see all the times and rates over on their shipping page.
