So, Instant Knock Out make its main goal, it melts your fat quite effectively. 

A little About Who is Making It?

Roar Ambition’s Instant Knockout is a very well known company in narrow niches, especially from testosterone boosters and fat burners. And as we already know, if the niche is smaller, usually the quality of the product is better. Also, it was formulated to be used by boxers and MMA fighters, for pre-fighting preparation when fighters had to get rid of the extra fat.

What does It Include?

  • Green Tea Extract – one of the best-known ingredients in fat burning pills. So, green tea has a lot of different benefits, and one of them is fat burning support.  It also is giving you a good boost of energy and increasing your mood during the day. (1)
  • Cayenne Pepper – It is well known as a metabolism booster, which allows your body to burn more calories, and burn fat. Also, it is one of the ingredients which make Instant Knockout a thermo-fat burner. Why? Because it helps you to burn fat by increasing your metabolic processes by increasing your body temperature. (2)
  • Glucomannan – contains high amounts of dietary fibers, which should reduce your appetite and that way makes you lose weight of course. It also is absorbing the liquid and that makes you feel full and just avoid the extra snacks during the day. (3)
  • Caffeine Anhydrous – caffeine is a good way to increase your metabolism and also improves your body’s ability to break down stored fat. So, caffeine anhydrous is one of the purest and effective forms of caffeine. Usually, it is used in fat burning pills to increase the effect. (4)
  • Vitamin B6 – It showed with the time that it can help to improve your overall energy and when you are on calorie deficit it helps a lot. In Instant Knockout in its natural form of pyridoxine. (5)
  • Vitamin B12 – Most of the B group Vitamins help your body to transform your carbs to glucose which is easier to use for energy and does not store it in your body.
  • Chromium – is a mineral that enhances insulin, a hormone that’s important for turning food into energy. So, there are claims that chromium supplements can lower your appetite, make you feel less hungry. (6)
  • Zinc – well, Zinc helps you to increase and maintain testosterone levels, and also it helps to recover faster and increase the quality of sleep. If your testosterone is higher then the metabolism is faster too, and this also makes you fat burning easier. (7)
  • Piperine – This ingredient helps you to absorb food nutrients faster. Also, it has anti-inflammatory effects what is an overall good thing for your health. (8)
  • Green Coffee Bean – So, green coffee bean extract comes from coffee beans that haven’t been roasted. Coffee beans contain compounds as chlorogenic acids. So, these compounds have antioxidant effects, help lower blood pressure, and also help you lose weight. (9)

Pros and Cons in Details

Instant Knockout is a very good fat burning supplement. But oh well, unfortunately, there is no ideal supplement, and Instant Knockout has its own pros and cons. So, we will start with the pros, and Instant Knockout has many more of them.


  • It includes such ingredients as green tea and also green coffee beans, which give you a thermogenic effect. That means that they help your body to generate heat, increasing your metabolism and it allows your body to burn calories faster. 
  • It includes Zinc, it is a mineral that enhances your muscle recovery, increases your sleep quality, and raises your testosterone. So, if you sleep better, your body is not producing cortisol, stress hormone, and that let your body work properly and burn fat easier. Also, if your testosterone level is higher, fat will but faster. This hormone is related to your metabolism speed. 
  • Chromium is one of GDA (glucose disposal agent), and it helps your body to handle carbohydrates more effectively. So if you get rid of carbs faster, it will be easier to get rid of fat too. It will help your body to store glycogen in your muscles, not in fat reserves. 
  • Glucomannan is a fiber that helps your body to get rid of unwanted toxins. Also, it will help you to avoid bloating and improve your bowel movements. 
  • It doesn’t have any sweeteners, this is actually good, you will not try to cheat with your body. When your body is getting aspartame or smth else, the body still thinks that it is getting sugar and it can make your weight loss slower. 
  • Increase focus, you will be able to concentrate on your workout better, and it will give you some energy boost as well. 


  • Price is a little higher than ordinary fat burners, but you need to understand that natural and good quality product can’t cost cheaper than ordinary products. Also, you will see the effect very fast though. Besides, you have good discounts if you buy more than one!
  • Portion size is big 4 pills, for some people it can be annoying, and I understand them. I hate it so many pills per day. If you are working out you are probably using more aother supplements and extra 4 pills will not make you happier. 
  • Too high in caffeine, if you are sensitive to caffeine, this supplement is not for you. It has quite a high dose. Even if it is more effective with this dose of caffeine, take it at least 4 hours before sleep, or you could have problems with falling asleep. 
  • It is not suitable for vegetarians – this one is short, some ingredients are from animal sources. So, it is not the best choice for vegetarians or vegans. 


Instant Knockout comes in pill form. Each bottle contains 120 capsules, which should be for a month. If you want to buy more there are different discounts and special offers available when you buy more than one pack!

As per the manufacturer’s recommendations, you should take Instant Knockout that way:

  • One capsule first thing in the morning
  • Capsule before lunch
  • One capsule in the afternoon
  • And also one capsule before dinner

P.S. Avoid this fat burning pills before sleep (at least 4 hours)

Also, it is better to take breaks every month after you use it. The thing is that body can adapt to everything, so it is better to take a break and to give the body forget about its effect. 

Note: we do not recommend you take ANY supplements featured on this site without consulting a doctor first.

Best Alternatives or The Best Competitors

Well, we have mentioned before, that we also have some problems choosing between Instant Knockout and few more fat burning supplements. One of them is PhenQ and another Transparent Labs Fat Burner. So, these three competitors are the best on the market, and it is really difficult to choose between them. 

Probably the most important aspect of what makes a fat burner a good one is the amount and dosage of ingredients. So first we want to compare them: 

  • Green tea extract
  • L-Theanine
  • Rhodiola SP 
  • Caffeine
  • L-Tyrosine
  • Cayenne Pepper
  • Forslean (10% forskolin)
  • Green Tea (50% EGCG)
  • 5-HTP
  • L-Tyrosine
  • L-Theanine
  • Caffeine Anhydrous
  • Salicin (White Willow) Bark Extract
  • Cayenne Pepper Extract
  • Synephrine HCl
  • Vitamin B6 (As Pyridoxine HCI)
  • Zinc (As Zinc Oxide)
  • GTF Chromium (As Picolinate)
  • Green Tea Extract (Leaf)
  • Vitamin B12 (As Cyanocobalamin)
  • Green Coffee Extract (Bean)
  • Cayenne Powder (Fruit)   
  • Glucomannan (Konjac Root)
  • Caffeine Anhydrous
  • Black Pepper Extract

As you possibly see the leader with pros is PhenQ, but it is the most expensive though. But also the cons of Instant Knockout are so miserably small, that you will possibly even not notice them. The only reason you should avoid to buy it is if you are sensitive to caffeine.
