As a bodybuilder, the cutting cycle is your opportunity to reduce your body fat percentage and allow your muscles to come out. It improves your physique by boosting muscle definition as well as vascularity. However, finding a good fat burner for the job can be very difficult. Some fat burners in the market cannot deal with the fat without touching your lean muscle mass. Others may leave you seriously fatigued, which will make it difficult for you to keep up with your training routine. Fortunately, there are a few fat burners out there that tick every relevant box. Instant Knockout is one of such fat burners if user reviews are anything to go by.

What is Instant Knockout?

Instant Knockout is arguably the best fat burner for men right now. The supplement is manufactured by a company known as Roar Ambition. Initially, Instant Knockout was being made for professional boxers and MMA fighters only. However, the supplement proved to be so successful that it soon became popular and available for the fitness and bodybuilding industry.

Instant Knockout is formulated using a 100% natural formula. There are no artificial or synthetic additives in this formula. Therefore, it’s also one of the safest fat burners you can use.

Something else amazing about this supplement is the science behind it. Instant Knockout’s formula compromises of only 10 ingredients. These ingredients have solid scientific studies showing how effective they are in burning fat and dealing with weight loss as a whole. They are also well-dosed to ensure that they actually have an impact. In case you didn’t know, some fat burners will have all the right ingredients but in insufficient doses, and that’s why they produce little to no results at all.

You should know that Instant Knockout is better suited for men and not women. Sure, some women, especially female bodybuilders, can use it, but in general, Leanbean has proven to be the better fat burner for women than Instant Knockout.

How Does Instant Knockout Work?

Instant Knockout works in three main ways:

First, it increases the body’s metabolic rate. A healthy metabolic rate makes sure that your body is breaking down food and fats efficiently to prevent excessive storage of fats and produce energy. However, for bodybuilders, normal metabolism may not be enough. You need to increase it even further to push your body fat percentage lower. Instant Knockout contains several key ingredients that will stimulate your metabolism and increase fat breakdown even when you are at rest. It burns stubborn fat on different parts of your body, including your arms and the abdomen. Seasoned bodybuilders use this strategy to get that ripped physique.

Cravings can make losing weight very difficult. You can even end up in a cycle where you are burning some fat, but then your cravings make you eat lots of calories, which basically ends up getting converted and replacing all the fat you have lost. Instant Knockout ends this cycle by curbing your cravings. It suppresses your appetite and reduces the number of calories you are taking. Wouldn’t that leave me feeling weak? No, it wouldn’t.

In addition to increasing metabolism and curbing cravings, it also increases your energy levels. This is partly due to the fat breakdown where your body taps into its fat reserves for fuel. An increase in energy should help you stay active even though you are not eating so much food.

The energy is also important because Instant Knockout is not a magic pill. Yes, it maintains high metabolism even when you are not doing anything at all but to achieve the best results, you need to support the supplement with a proper workout routine. You also want to watch your diet.


The formula contains the following ingredients:

  • Green Tea Extract

Green tea extract is a popular ingredient in the weight loss world simply because it works. The extract is rich in catechins, which produce several effects in the body. They spike your metabolism allowing your body to breakdown more adipose and at a faster rate.

Green tea extract also stimulates your body to use the stored adipose as a source of energy. Therefore, you won’t just be losing fat, but you will also enjoy a boost in energy, which should help you crash your training sessions.

  • Cayenne Pepper Seeds

Cayenne pepper is a powerful thermogenic compound. It increases your body’s core temperature, thus allowing you to burn more fat. It also increases fat oxidation and energy expenditure.

Cayenne pepper contains a bioactive alkaloid called capsaicin. This compound boosts insulin sensitivity and improves carbs storage.

  • Glucomannan

Glucomannan is a natural fibre obtained from the Konjac plant. It’s also popular in the weight loss industry because it helps with appetite suppression. This fibre absorbs water to form a thick gel that fills up your stomach. It’s also never digested, so you will feel full for quite a long time. This should be enough to keep you from eating unnecessarily.

  • Caffeine Anhydrous

Caffeine anhydrous delivers several benefits. First, it increases energy levels, which explains why Instant Knockout users never complain of fatigue or lethargy. Being a stimulant, you can also expect a boost in focus and concentration.

  • Vitamin B6

Vitamin B6 increases fat oxidation and metabolism. It also improves amino acid absorption to support muscle building but on a limited scale.

  • Vitamin B12

Vitamin B12 boosts the metabolism of fatty acids and improves the digestion of carbs. It’s also known to support protein synthesis, which can boost muscle growth.

  • GTF Chromium

GTF Chromium contains chromodulin, which improves the metabolism of fats and sugar. It allows your body to use the stored fat as a source of energy, resulting in fat loss and high energy levels.

This nutrient also controls the storage of carbohydrates in the body by regulating insulin. On top of that, studies show that it curbs cravings and appetite.

  • Zinc

Zinc stimulates the body to utilize carbs and fat for energy. It also improves testosterone production, a hormone that’s known for boosting muscle growth, strength, stamina, libido, and physical performance.

  • Piperine

Piperine prevents fat cell accumulation. It also increases metabolism, thermogenesis, and supports an efficient digestive system.

  • Green Coffee Bean

Green coffee beans are unroasted coffee beans. They typically contain more nutrients than roasted coffee beans because they are unprocessed. Green coffee beans contain chlorogenic acid, which fights sugar cravings and lowers cholesterol levels.


You can expect the following Instant Knockout results:

  • Fat loss
  • High energy levels
  • Fewer cravings
  • Better mental focus

Side Effects

Is Instant Knockout Safe? Yes, Instant Knockout is generally safe and free of side effects. So many men have used it successfully without having to deal with any complications.

That said, the fat burner can still produce some side effects if the user is sensitive to one or more of the ingredients used. It also causes adverse reactions when overdosed. For instance, you may experience some digestive issues, sleeplessness, and jitters due to the presence of caffeine in the formula. You can easily avoid all this by sticking to the recommended dosage.

Avoid using Instant Knockout without a doctor’s approval if you are already taking other medications. You should also try to avoid drinking coffee when using Instant Knockout.


The recommended dosage is four capsules per day, which should be split into four servings. Take the first capsule early in the morning, another before lunchtime, the third one in the afternoon, and the last capsule before your evening meal. This makes sure that there is enough of the supplement in your system at all times to produce the best results.
