Instant Knockout vs PhenQ Fat Burner Comparison

In this review, we’ll be comparing Instant Knockout vs PhenQ fat burner supplements head to head. The general consumer of supplements is getting wiser – this is a good thing. Don’t waste your time picking up the product that has the best packaging or promises what you are looking for – they all do this!

Instead, look for the top fat burner ingredients and go from there. Better still, take note of what you believe looks like a good product and do your research. This is where Clean Lean Machine comes in. We compare various supplements so you don’t have to spend hours researching each product and the individual ingredients.

We have taken this labor upon ourselves so you can just read through and find a fat burner that is effective, but also safe to use.

Today we are looking at the qualities of Instant Knockout and PhenQ and the first thing we noticed about both of them is that they stay away from proprietary blends.

This is what we like to see the more open a company is about their ingredients and dosages, the better for the consumer. How else can you tell if a supplement is underdosed and ineffective, or has too much of certain ingredients and is potentially dangerous?

Now that is just one box that can be ticked from both of these fat burners, let’s see what else a good fat burner should do:

  • Burn Fat (Obviously!)
  • Suppress Appetite
  • Increase Energy
  • Be 100% Safe

Let’s get to know these two a little better to start with.

Instant Knockout vs PhenQ: Who Makes These Fat Burners?

Roar Ambition

Instant Knockout Review

The people that make Instant Knockout are Roar Ambition, and they have an excellent reputation in the supplements world.

All of their products are 100% natural and this goes for their other popular supplements such as their Testosterone booster TestoFuel.

Click on YouTube to see the various testimonials and if the average Joe isn’t enough to convince you then the UFC fighter Diego Sanchez might just do that. He is one of their flagship athletes after all and if it works for him when cutting weight then it must be good.

They have a money back guarantee so they clearly back their product and we are pleased to say, we haven’t heard of anyone around the industry who has needed it!

Wolfson Berg

This is the company behind PhenQ, although there isn’t a lot of information to be found on them. Their website is minimalist yet you can find out that they research, develop and manufacture nutraceuticals.

They work with over 100 brands around the world and it seems that they have a portion of their business dealing with private label brands.

They are based in Cyprus, making the name of the brand a little curious – Wolfson Berg doesn’t sound Greek to us, but seriously, if they are shipping out of there then you can only hope it arrives in the time it would from the US or UK.

Ok, so not a great deal of info for us to start with for PhenQ but we have the ingredients list which is all we need to discover just how good this fat burner is.

The Fat Burner Ingredients

So we know there are no proprietary blends for either of these so now let’s see what they are made of. This is where we will find out if either of these is worth buying, and if either is a supplement you would want to avoid.

Instant Knockout Ingredients

Instant Knockout fat burner Ingredients

You will be hard-pressed to find a more effective overall ingredients list here. They have selected a great array of some of the best fat burning ingredients around.

Green Tea Extract

A really good start here and a common ingredient in some of the better fat burners on the market for a reason. Green Tea Extract contains catechins which help get the thermogenic process going.

Thermogenesis is great because it heats your body up on the inside, causing you to burn fat as a way of cooling yourself down. Clever stuff indeed.

It has other benefits as well, it is often believed to be good at limiting the amount of fat your body digests so you actually take on less fat as well as burn what you do have.

In all of this Instant Knockout vs PhenQ review, this might be the best ingredient.

It also helps your body to burn more fat during exercise so it uses the stuff you don’t want.

Cayenne Powder

If you are not a fan of spicy food then you will like the fact that you can get all it’s fat burning benefits without having to consume the spice.

Another thermogenic ingredient it is also good for suppressing appetite and making you feel fuller for longer. Two of the essential elements for any fat burning supplement in one ingredient.

The 100 mg contained in Instant Knockout is more than enough for you to receive the benefit.


Another great fat burner ingredient that isn’t found in enough supplements in our opinion. Too many fat burners are using unreliable research when including certain ingredients but Glucomannan has the backing of various studies behind it here.

It absorbs water in your body and expands in your stomach. This is where you want to feel as though you are full and that is exactly what this ingredient does.


Everyone needs an energy boost, especially when taking on fewer calories through dieting. A good fat burner often includes a hit of caffeine and it is not just because you need the energy for your workout.

Caffeine also helps to get your metabolism going which is useful when looking to lose weight.

Black Pepper Extract

Often referred to as Piperine, this is a useful ingredient when used alongside quality nutrients. The good news is that Instant Knockout has many proven fat burner ingredients so the fact that Black Pepper Extract increases the effectiveness of these ingredients is a bonus.

PhenQ Ingredients


Calcium Carbonate

The ingredient with the highest dosage is usually the flagship of the supplement, the big cheese, the big hitter, the….you get what we’re saying!

Well unfortunately for PhenQ, although this is sometimes referred to as an appetite suppressant when combined with protein, there aren’t many concrete studies to support this, and there is also no guarantee that every consumer will be piling on the protein.


A good inclusion for sure and the benefits have already been talked through with Instant Knockout. The amount within PhenQ is sensible and won’t cause any side effects so you should get the energy boost as well as increased metabolism as a result.

Capsicum Extract

Derived from peppers it is similar to Cayenne Pepper. The thing here is, although it should have the thermogenic properties and appetite suppressant capabilities like Instant Knockout, only it has a minimal 8 mg, compared to Instant Knockouts 100 mg – so won’t be anywhere near as effective, unfortunately.


There are a few studies to support this ingredient as being an effective ingredient. Known as a prickly pear in food form it does have a good level of fiber which is thought to fill you up for longer.

However, it has been shown to cause some unwanted side effects such as headaches and diarrhea.

Instant Knockout vs PhenQ Side Effects

Whilst Instant Knockout is completely free of side effects (most likely because of the 100% natural ingredients), the same can’t quite be said of PhenQ.

The inclusion of Nopal means there is the possibility of some inconvenient side effects such as headaches and diarrhea. Although these aren’t the worst – they’re not the best either!

Instant Knockout vs PhenQ Pros and Cons

Instant Knockout vs PhenQ Conclusion

Winner: Instant Knockout

Instant Knockout Review

In this instance, it really was too good for PhenQ. With its blend of proven fat burners at effective dosages, without any side effects – there aren’t enough fat burners on the market like Instant Knockout.

The company Roar Ambition has an excellent reputation and if more of the industry was as open as they are then it would be a better place.

Unfortunately for PhenQ we found their product to be a bit strange. For the most part, it has some safe ingredients, they just weren’t very good. So not good, but not particularly bad either.

It did contain some good fat burner ingredients so you will find that some people will get some of the benefits, but if you are paying money for a fat burner, then you want it to be as effective as possible.

This is why we like Instant Knockout, it has so much going for it. To find out more about this product and what it can do for your fat burning goals, read our in-depth Instant Knockout review.
