Instant Knockout vs Hardbodys Black Label Accelerator

If burning fat is your end goal, then our Instant Knockout vs Hardbodys Black Label Accelerator comparison might have a couple of products to help push you over the line.

Getting shredded isn’t easy. It takes discipline and hard work. But using the help of an effective fat burner can make things a lot easier.

The problem is, there aren’t that many good ones. We have reviewed 100s of supplements and know that there is way too much filler on the market.

So, is either product going to be what you need? In order to be the answer to your prayers, they must do the following:

  • Burn fat effectively
  • Be safe
  • Suppress appetite
  • Increase energy

Anything less than this will not suffice. Let’s start by getting to know them a little better first.

Instant Knockout vs Hardbodys Black Label Accelerator: Who Makes These Fat Burners?

Instant Knockout Review

Here we have the company behind Instant Knockout.

They have a great reputation for making quality products and this is evident in the amount of before and after profiles you see online.

Roar Ambition review and amend their own ingredient profiles regularly to make sure the customer is getting the best possible version at all times. They also have generous money back guarantees (90 days for this product!) that ensure the user can really try the product on for size.

All supplements should be risk-free purchases so we commend them for this.

They also make everything in facilities that are FDA approved to GMP certifications.

Roar Ambition has some impressive endorsements. UFC fighter Diego Sanchez puts his name to this fat burner and uses it to make weight before a bout.

Hardbodys Black Label Accelerator

Hardbodys Supplements

This company was founded by Law and Patricia Payne. This husband and wife team have impressive CVs having written for a lot of fitness magazines as well as featuring on TV numerous times.

With different certifications in the nutrition world and a lot of books to their names, they have built up an impressive amount of credentials.

We can’t work out if they offer a money back guarantee for this product. On one side they say that their returns policy lasts just 7 days. On the other hand, they say that they will buy their product back from you if you don’t love it!

It isn’t particularly easy to read the Hardbodys website because they use a bold text but they do have a wide range of products. These range from detox and cleanse options to pre-workout drinks.

Instant Knockout vs Hardbodys Black Label Accelerator Ingredients

This is where we can get to know both products and see which is the better option. Neither uses proprietary blends which is always a good thing.

The suggested serving does favor Instant Knockout though. Their advice of taking one capsule 3-4 times a day really spreads out the benefits. Especially compared to the one capsule, twice a day from Hardbodys Black Label Accelerator.

Mutual Ingredients


A solid start from both.

We always prefer to see proven ingredients and Chromium is one of them. WebMD advise that it can decrease LDL (bad cholesterol) levels in people who have lower blood fat levels.

It could also be useful for communicating with the brain to tell it that the body is full. In this sense, it works as an appetite suppressant.

The 150 mcg in Hardbodys Black Label Accelerator and the 100 mcg in Instant Knockout will both be of benefit.

Green Tea Extract

Another effective fat burning ingredient.

This is a versatile one that works as a thermogenic. This means it heats the body up on the inside, causing it to burn fat to cool itself down again.

It contains a milder caffeine that the likes of Caffeine Anhydrous as confirmed by WebMD who advise this is about 2-4% Caffeine. This is beneficial as it also provides a boost in both your thinking and alertness.

Green Tea Extract also contains polyphenols which reduce oxidative stress and leave a calming effect.

A great ingredient that gets the dosage it deserves from both, The 400 mg in Hardbodys Black Label accelerator and the 500 mg in Instant Knockout are both very effective dosages.

Cayenne Powder

More proven fat burners.

And another thermogenic, this means you will be burning even more fat whilst you rest!

WebMD advise that is is also good for appetite suppression. They say that it has been found to curve appetite, especially in those who do not already eat spicy foods.

At 80 mg, Hardbodys Black Label Accelerator have included a good amount. The 100 mg in Instant Knockout is just a little bit better.

Black Pepper Extract

Misspelled on the Hardbodys Black Label Accelerator label as Plack Pepper Extract (that never looks good!) it is a useful ingredient.

This is because Black Pepper Extract actually increases the effectiveness of the other ingredients it is consumed with.

Because both products include some good ingredients, this is of benefit. At 6 mg in Hardbodys Black Label Accelerator and 10 mg in Instant Knockout, you are getting a good amount in both.

Individual Ingredients

Instant Knockout

Caffeine Anhydrous

A very effective ingredient for a fat burner from Instant Knockout.

It wouldn’t be out of place in a pre-workout or even a nootropic.

The energy increase from consuming Caffeine is obvious. This is going to be great if you are one of those people who use fat burners alongside a diet that restricts calories. Also, your workout will be enhanced by this as well.

The anhydrous type here is basically just a powdered form that is easily absorbed by the body.

It will also get your metabolism going and the 350 mg in Instant Knockout will be well tolerated as it is to be taken across 4 servings. A safe and effective dosage.

Green Coffee Bean Extract

Another great fat burner.

This is coffee before the chlorogenic acid and color has been removed. This acid is really good for fat loss because it stops us from storing as much fat and keeps blood sugar levels under control.

WebMD says that one study that looked into adults with obesity found that taking Green Coffee Extract for between 8 to 12 weeks meant more weight loss for those when compared to others taking a placebo.

A great ingredient and the dosage of 100 mg is another optimal amount.

Vitamin B6

B6 works in a similar way to a lot of the other B-vitamins in that it helps us to make energy from food. It converts them into glucose to be used as energy.

Vitamin B6 also has links to boosting metabolism which makes the 5 mg dosage a useful amount.

Vitamin B12

Another B-vitamin but one that stops the body from storing as much fat.

You can’t create your own so supplementing it is a good idea. This is, even more the case for vegetarians and vegans as prominent sources are fish, meat, and dairy.


Another useful ingredient but how does it benefit a fat burner?

Zinc stops us from storing fat and also helps with glucose metabolism.

If consuming fewer carbs is making you grumpy then it might be useful as according to, Zinc has also been shown to improve mood.

The 10 mg is another great dosage.


Here we have a proven appetite suppressant.

It is a dietary fiber that absorbs water and swells in the stomach which makes the user feel full. It also stops you from needing to snack between meals.

Such a good ingredient gets the dosage it deserves and the 500 mg is a big amount.

Hardbodys Black Label Accelerator


Otherwise known as vitamin B3 it is a useful ingredient.

Possibly included because of its use for insulin levels but more likely an ingredient found in multivitamins. This is because it helps to create energy. By breaking down carbs and using them for fuel it is a typical B-vitamin in this sense.

This makes it a useful inclusion but does say for it to be effective you need a gram of it. Since the daily serving is 24 mg, you aren’t getting anywhere near this amount.

A good ingredient that has not been dosed well.

Apple Cider Vinegar

An ingredient that gets a lot of hype but is it deserved?

There are studies that show that Apple Cider Vinegar can slow the rate that food exits the stomach. This makes the user feel fuller for longer. If this was the case then it is an appetite suppressant making it a good fat burner ingredient.

It can also be consumed before meals to stop the body from absorbing so many carbs. does discuss one study that showed it could help with fat loss. The issue with it though is that it doesn’t have a great deal of evidence to support it. Examine also advise that it remains a very cheap and safe ‘home remedy’ for fat loss.

So this could be a good inclusion and it is likely that the 160 mg is enough to do something here.

Cinnamon Bark Powder

Not the best ingredient although a lot of people know it as having health benefits.

It is thought to reduce blood sugar levels post meal but this is disputed by some.

Cocoa Seed Extract say that Cocoa Seed Extract can help to increase energy levels.

Dark chocolate of 80% cocoa or more appears to have a similar effect and it is the flavonoids that might be good for decreasing blood pressure levels.

Although, WebMD do advise that it is unclear how flavonoids work in the body. They do say that flavonoids appear to cause a relaxation of veins. This could lead to lower blood pressure.

This is nice and everything but we aren’t looking for promise, just proven fat burning ingredients.

Ionic Alfalfa Leaf Extract

Not the most famous fat burner but it might help to boost metabolism.

There are links between Ionic Alfalfa Leaf and enhancing overall wellbeing but it is another ingredient that shows promise rather than has the backing of numerous human trials.

WebMD advise that taking alfalfa seems to lower total cholesterol and ‘’bad’’ low-density cholesterol in those with high cholesterol levels.

The line seems to be potential once again so the 30 mg per day is unlikely to have a true effect on fat burning.


Not a great ingredient once again.

It might help to increase energy levels in the muscles as it is a source of energy that our bodies create from the food we eat.

The theory behind its inclusion is probably that more it is even better. The problem with that is as WebMD describes – taking ribose supplements by mouth does not increase power. It also does not increase muscle strength in trained or untrained individuals.

A poor ingredient to end on.

Instant Knockout vs Hardbodys Black Label Accelerator Side Effects
