Instant Knockout vs Thermopure Fat Burner 

Here we have two of the well known fat burners available today. Our Instant Knockout vs Thermopure fat burner comparison will help us to find out which is the better option for you.

With any growing industry comes a lot of dodgy products, so our job here is to make sure that you don’t go for any sub-par products. We only recommend the very best and have our own reputation for being hard to please.

This means you can be assured that you are finding quality products when looking at the products we recommend. In terms of what we are looking for today, if either of these products is going to impress us, they will need to do the following well:

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

Anything less than this is not good enough and believe us when we say, we will be letting you know about it.

So, let’s get to know these products a little better.

Instant Knockout vs Thermopure: Who Makes These Fat Burners?

Roar Ambition 

The people behind Instant Knockout are UK based company Roar Ambition.

They have a great reputation online for customer service, probably because of their generous money back guarantee and the fact that they review and amend their ingredient profiles regularly.

This ensures the customer is getting the best version of the product possible. On top of this, there are loads of positive testimonials from people willing to post their before and after shots online and on YouTube.

They also have some impressive endorsements with UFC fighter Diego Sanchez putting his name to this fat burner.

They ship worldwide directly from the USA and UK.

They also make the excellent T booster TestoFuel, one of our highest ranking supplements.

My Proteinthermopure

Here we have the people behind Thermopure and although the label here is one of the blandest we have seen (and we’ve seen plenty) this doesn’t necessarily mean a bad product.

They are another company based in the UK and have decades of experience here so it comes as no surprise that their website has a ton of supplements.

They seem proud of their natural approach, much like Roar Ambition and even have plenty of fitness and health articles. This is even broken down to your sport of choice which is good.

We couldn’t find a money back guarantee, instead, you get 14 days to cancel your order. We prefer money back guarantees as there isn’t anything that really ensures you are getting something that will work.

Let’s see if all their experience translates into a good product.

Instant Knockout vs Thermopure Ingredients

Now we can really get to see how good these fat burners are.

Thankfully neither product use proprietary blends so we can really see exactly what dosages go into each capsule.

Mutual Ingredients

Green Tea Extract

An excellent start from both, this is one of the top fat burners.

This is more than your evening tea of choice it is great for getting your metabolism going through the catechins. It will even help you to get the most in terms of fat burning out of exercise.

This way it helps you to burn the fat you do have effectively.

The 500 mg in Instant Knockout is an optimal dosage that will work wonders, the 375 mg in Thermopure will also help.

Vitamin B6

Another good inclusion and yet another metabolism booster.

Not only will this speed your metabolism up, but if you are into the bodybuilding lifestyle then you will enjoy the other benefits. It is also great for helping your body to absorb protein, great news for the muscles!

There is 5 mg in each of these supplements is plenty enough to get things going.

Vitamin B12

Another good inclusion from both that will help to burn fat here.

The increase in energy levels that you will receive from taking this will really help to boost your output in the gym which is important especially if you are taking on fewer calories than usual.

It also boosts your metabolism (of course!). Converting food into energy to stop your body from eventually storing it as fat.

Both products have dosed this well.

Cayenne Powder

One of our favorite fat burning ingredients.

If you aren’t a fan of spicy food then a supplement such as a fat burner is a great way of receiving all the benefits without the heat.

It is a great thermogenic ingredient. This is when your body heats up inside, then burns fat to cool itself down.

On top of this, it is also a very good appetite suppressant. This is because it swells in your stomach, making you feel full. Exactly the sort of ingredient we need here.

At 100 mg, Instant Knockout have included what you need to really get things going. Thermopure have only added half of that which isn’t really enough to do what you need it to.


A very beneficial inclusion here.

Chromium is good for regulating insulin levels. This means the blood sugar levels are kept stable. When the opposite occurs your body feels the need to snack to keep the balance. Anything that can stop this is a sensible idea.

Both products have plenty of products that help you to burn the fat you do have, thankfully they also use appetite suppressants as well.

Instant Knockout has the more beneficial dosage here.


Thermopure haven’t gone into great detail in terms of their caffeine but we know that Instant Knockout contains Caffeine Anhydrous, the most effective kind in our eyes.

This is a dried version that is absorbed much faster by your body. Caffeine is another great metabolism booster, in fact, it seems to get everything going. The energy increase is also vital if using a fat burner alongside a workout routine.

The 150 mg in Thermopure is a nice boost but really you want a bit more to get you going. Since Instant Knockout is to be taken 3-4 times a day, the 350 mg in it is spread out and you will feel full of energy for more of the day.

Black Pepper Extract

Not a direct fat burner but you will recognize this from various supplements for a reason.

Basically, it is very good at bringing out the best in the other ingredients. It enhances their capabilities so if a fat burner contains a lot of good ingredients as both of these products do, it will make the supplement even better.

The 5 mg in Thermopure is ok, but the 10 mg in Instant Knockout is even better.

Instant Knockout vs Thermopure Side Effects

The good news is that neither product has anything in them that would make you think twice about using it.

As always, we advise you to check the labels in case of allergies but since they both use natural ingredients, you should be fine. The only small bit of advice we would suggest is to build up your tolerance to caffeine if you are not used to taking such levels.

Instant Knockout vs Thermopure Conclusion

Winner: Instant KnockoutInstant Knockout Review

We have said this many a time, it will take something huge to beat Instant Knockout. It has so many of the top fat burner ingredients but at optimal dosages. It even contains Glucomannan, another great appetite suppressant as well as Zinc, one of the great fat burner ingredients.

No other fat burner can keep up with it. Thermopure has a lot of the good ingredients, but like with Cayenne Pepper and Black Pepper Extract, only went with half the amount of Instant Knockout.

It is a decent product but we don’t really pay attention to anything that is only ‘OK’. We look for a fat burner that will deliver results, like Instant Knockout.

With no side effects, it is completely safe to use and the caffeine will get your energy levels to where you need them. We still haven’t seen a fat burner like it, and we’ve seen loads!

It is the true accompaniment to anyone looking for a boost for burning fat. To find out more about this top product, check out our Instant Knockout review.
