My Instant Knockout Review

instant knockout fat burner

What’s so good about Instant Knockout?

Many people find it difficult to shed fat and it is probably why you are here now reading this review, one of the main questions asked is “How to build muscle and burn fat?”

It is widely known that unless you have surgery you cannot dissolve localised fat deposits i.e. doing just sit ups for hours on end will not simply reduce belly fat, however, many people still do not fully understand this.

Therefore numerous products have come on to the market to help people metabolise those unwanted gains.

Some of these products are greater than others and started life on the market not necessarily for Joe public…one such product is Instant Knockout by Roar Ambition, the guys who brought us our favourite testosterone booster: TestoFuel.

Instant Knockout was originally developed for pro MMA fighters and boxers. It’s being used by UFC fighter Diego Sanchez to cut his weight from 190 pounds to a featherweight 145 pounds which you can see below, as you will see, it is an impressive product.

Therefore I felt after using it that I should do my own review of Instant Knockout.

What can a fat burner really do?

You may well be surprised actually.

The idea that an effective fat burner just magically makes your waist smaller is far from the truth.

However, only the effective fat burners contain a number of ingredients in correct doses that work harmoniously and through a number of outcomes help you lose fat mass, not muscle.

Their benefits include, but are not limited to:

  • Increase energy – This will help you be more active and stimulate you for effective workouts
  • Thermogenic – These ingredients will increase the temperature of your core which increases calorie expenditure
  • Appetite control – The ability to feel fuller and not to fall for sweet, calorie laden treats

As a result I tend to supplement my exercise regime with a fat burner supplement.

I have found Instant Knockout to offer the best results and as a result I try to use that daily.

First look

The packaging is crisp, clean and professional looking; it doesn’t look amateur whatsoever and again, as with TestoFuel, time and money has been spent on the design even to the point that the bottle is shaped like a fist…a nice little acknowledgment to the MMA element in its conception.

Ingredients: The Science

Roar Ambition are here to make an impact on the supplement world with all the ingredients delivered straight up clearly stating the facts with good, solid instructions and with no proprietary blend like some other lesser products out on the market.

All the ingredients listed are natural and proven to metabolize fat burn. The product is natural, safe and is backed with plenty of research studies; if it is good enough for a UFC fighter to drop a weight it is for us mere mortals!

  • Vitamin B12
  • GTF Chronium
  • Vitamin B6
  • Green Tea Extract
  • Zinc
  • Green Coffee Extract
  • Cayenne Powder
  • Glucomannan
  • Caffeine Anhydrous
  • Black Pepper Extract

Let’s take a look at the studies…

Green Tea Extract:

Clinical studies suggest that green tea extract may boost metabolism and help burn fat.

One study found that the combination of green tea and caffeine improved weight loss and maintenance in people who were overweight and moderately obese.

Some researchers think that substances in green tea known as catechins are responsible for the herb’s fat-burning effect.

Cayenne Pepper Seeds:

The hot and spicy taste of cayenne pepper comes from capsaicin, a compound found in many hot peppers.

Capsaicin is known to boost metabolism, causing the body to produce extra heat and burn more calories for fuel.


This is a soluble, fermentable, and highly viscous dietary fiber derived from the root of the elephant yam or konjac plant, which is native to Asia.

Preliminary evidence suggests that Glucomannan can promote weight loss.

Vitamin B6:

Using it in its most natural form, pyridoxine, B6 is an essential nutrient to raising the body’s metabolism and aiding the fat burning process.

Vitamin B12:

B12 fights fatigue, muscle wastage, boosts mood, cognition and is vital to many bodily functions including metabolism and food digestion.

So to put it bluntly, we need this for smooth operation and be able to smash those workout sessions which in turn helps you burn fat and lose those unwanted pounds. knockout fat burner ingredient panel


A study in 2013 showed that people suffering from obesity had low levels of Zinc. Also, if you are deficient in Zinc it means you cannot absorb the nutrients from your food in the intestine.

GTF Chronium:

Research suggests that chromium might improve weight loss in some people who are overweight or obese.

Green Coffee:

Evidence from research has indicated that the consumption of caffeinated coffee can lead to some reductions in long-term weight gain, an effect which is likely to be due to the known thermogenic effects of caffeine intake.

Black Pepper Extract:

Black Pepper is a source of piperine, a molecule that does not do much on its own but can inhibit enzymes that would attack other molecules.

Due to this, it is ingested alongside some supplements to increase their absorption rates.

Caffeine Anhydrous:

The purest form of caffeine available. This compliments the green tea and coffee plus the thermogenic effects of cayenne pepper.

It stimulates the central nervous system (CNS), heart, muscles, and the centers that control blood pressure to give you an extra boost and hit that PB.

Caffeine also increase resting energy expenditure.

It is worth noting that the product is manufactured in the USA in FDA and cGMP certified facilities.


4 pills per day; immediately when you wake and then with every meal. 4 pills spread evenly throughout the day is the optimum dose.

It constantly and consistently provides your body with all of the ingredients required to raise metabolism and burn fat.

The is important, because, if you get too much of certain ingredients, that what the body doesn’t need at the time will be wasted and you will not feel the benefit.

Therefore, if you have a massive dose of Zinc for instance yet your body is still processing and utilizing Zinc from a meal you’ve recently had it will only use what is required.

What the body doesn’t require at the time will let it pass. Thus, a higher chance of waste and less benefits.

There is a 30 day supply with every bottle.

This product is great for both men and women too!

My Instant Knockout Review Conclusion

As with many people (apart from hardgainers) I find it much easier to build muscle rather than shed fat; for me it is simple and much more enjoyable to hit my squat rack in the garage and do some big lifts instead of getting on my bicycle or going for a 30 minute jog in the rain.

As a result, you can lose that cut and shredded look that you truly want, especially in the warmer months.

However, since using Instant Knockout I have noticed extreme definition in my legs, chest and found my stomach to look much leaner as well as the area around my ribs.

I do not to do any isolated stomach exercises and rely mainly on my core lifts to strengthen and build my stomach muscles and since using Instant Knockout those muscles are now exposed.

One thing to note though, I wasn’t too keen on is the jittery feeling I got from taking it, I love my coffee too so doubling up on the caffeine wasn’t great and I had to ensure I cut my coffee intake (probably for the best).

Roar Ambition also do the same deal as with their TestoFuel whereby if you purchase 3 bottles you get a 4th bottle and a tee shirt free – it is a fairly large sum to stump up at once, so it may prevent some people getting the best deal but if you can stretch to it, it is a good offer.

If not, bottles can be bought separately. It costs around $59 / £35 for a month supply, if you buy them individually.

Overall I am really happy with the results. Instant Knockout combined with my cycling to work plus a ‘cleaner’ diet has helped me shift the unwanted fat I had gained when I was commuting 120 miles per day in the car.

However, I do eat my ‘cheat’ meals at the weekend plus I am partial to drinking quite a lot of alcohol during the weekend and even the odd glass of wine throughout the week.

Even so, with these naughty flaws of mine I am still able to lose the fat…

Therefore, if you are strict and have more will power your results will be better than mine!

Hear what others have to say about Instant Knockout…

The supplement industry is full of charlatan products containing ill research ingredients, unproven ingredients, low doses, proprietary blends and even dangerous ingredients.

And, as with medicines and other drugs, different supplements will have different effects on different people.

However, take aspirin for example. Aspirin will have a slightly different effect on person A compare to person B.

However, across the board the majority of people will all be able to take advantage of the benefits of aspirin with no harmful effects and just reap the rewards.

It is the same when it comes to choosing supplements.

We all know aspirin is effective and safe when taken as instructed. Tis is because millions have benefited from it.

So, when looking for a supplement, make sure you are able to research the ingredients and their effects, also look to see if other people are benefiting, too.

So, take a look at others’ feedback on Instant Knockout

Not to be out done by the ladies, Jeremy saw some really impressive results, too…
