Instant Knockout vs Finaflex PX Pro Xanthine

The fat burning industry is bursting at the seams with products like your uncle’s new shirt after Christmas dinner. Which of our Instant Knockout vs Finaflex PX Pro Xanthine will be a cracker and which one a turkey?

It is no easy feat, making a supplement that actually works. Unfortunately, there are more bad options than there are good. This is where doing your research really pays off.

In order to give us a product that you are really going to consider, these products need to do the following:

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

Anything less than this won’t go down well.

Let’s start by getting to know the people behind the products a little.

Instant Knockout vs Finaflex PX Pro Xanthine: Who Makes These Products?

Roar AmbitionInstant Knockout Review

The team that makes Instant Knockout are this UK based company.

They have a great reputation online with a lot of people posting their before and after profiles having used their products.

Everything is made in FDA approved facilities and there is a big 90-day money back guarantee when purchasing this product. This is great as it means purchasing is risk-free.

Also, Roar Ambition check and amend their ingredient profiles regularly. This means the customer is always getting the best possible version at all times.

They also ship directly from both the UK and US.

In terms of endorsements, theirs are impressive. UFC fighter Diego Sanchez puts his name to Instant Knockout, he uses it to make weight before a bout.

Roar Ambition also makes a Testosterone Booster called TestoFuel. This is endorsed by former Mr. Universe Robby Robinson.

Finaflex Finaflex PX Pro Xanthine

Now we have the US-based company behind our second product.

They have a lot of useful information on their site with a variety of health and fitness related articles available.

There isn’t a lot of company information on there though. This is a bit of a shame as it gives you a sense of what they are like usually. We also couldn’t see anything regarding a money back guarantee but this isn’t to say they don’t offer something.

The advice with this product is that one pill gives you focus, energy, and appetite suppression and that you can take a second.

There is a disclaimer on there that actually says all athletes who are subject to testing for performance enhancing drugs may test positive when using dietary supplements. We’re not sure if they are specifically talking about one ingredient of if this is a generic statement.

The company seems to sell well on Amazon. A lot of companies are starting to choose to not go down this route because of the fact that there are a lot of sub-par products on there.

Instant Knockout vs Finaflex PX Pro Xanthine Ingredients

Now we can really set these two apart.

The early signs aren’t great for Finaflex PX Pro Xanthine though, they use two proprietary blends that covers all their ingredients. This means they haven’t given the individual dosages of any ingredients, instead just an overall amount.

Also, Instant Knockouts suggested serving of one capsule 3-4 times a day really spreads out the fat burning benefits. This is a lot better than the one, possibly two capsules from Finaflex.

Mutual Ingredients


A good start from both and an ingredient that is very common in fat burners.

This is probably because of two reasons. Firstly, the energy increase is going to be very welcome. This is especially the case for anyone looking to use a fat burner alongside a diet that restricts calories.

Also, Caffeine really speeds up your metabolism. It is an ingredient you will find in many supplements including pre workouts and nootropics.

Finaflex PX Pro Xanthine has just labeled it as Caffeine. Instant Knockout has gone for Caffeine Anhydrous which is a powdered form. This is easily absorbed and for this reason, is found in various energy drinks.

Finaflex PX Pro Xanthine has put this ingredient in their blend that totals 425.5 mg per capsule. Given the fact that there are many ingredients in there competing for space, it is unlikely that this has been dosed too high.

Instant Knockout gives you a very effective 350 mg across 4 servings which should be well tolerated for most people.

Green Tea Extract

Another good ingredient from both.

A proven fat burner that is thermogenic. This means it will heat the body up on the inside, causing it to burn fat to cool itself down again.

It is the catechins in Green Tea that are really of use. They are antioxidants that help to fight disease as well as aid weight management. backs this up by saying they are anti-obesity and anti-diabetic which makes this ingredient even more impressive.

Green Tea also has links to enhancing endurance levels.

WebMD says that Green Tea is a milder stimulant than Caffeine Anhydrous and contains just 2-4% Caffeine. This gives you an increase in your focus and alertness.

The proprietary blend in Finaflex really is a dampener as we have no idea if there is going to be an effective amount. Instant Knockout has included a big 500 mg per day. This is bigger than the first proprietary blend in Finaflex combined.

Individual Ingredients

Instant Knockout


Another impressive ingredient.

WebMD tells us that this can decrease LDL (bad cholesterol) levels in people who have lower blood fat levels.

Some studies have even shown Chromium to communicate with the brain to tell the it that the body is full. This means it works in a way an appetite suppressant would.

At 100 mcg you are getting a useful dosage from Instant Knockout.

Cayenne Powder

One of the best fat burner ingredients because it works in two of the best ways.

It is another thermogenic, meaning your body will be burning even more fat as it rests.

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

An ingredient that is great in more ways than one and the 100 mg is another optimal dosage.

Black Pepper Extract

An indirect fat burner but still a useful ingredient.

This is because it enhances the capabilities of the other ingredients it is found with. This means if the other ingredients are good, this product is made even better.

Towards the end is where you will know for certain whether this is truly good or not but the signs are looking positive so far.

Green Coffee Bean Extract

Another really good ingredient.

Green Coffee Bean is just coffee before the color has been roasted out. It is also coffee before the chlorogenic acid (that is useful for fat burning) has been removed.

It prevents the body from storing as much fat and keeps blood sugar levels under control.

WebMD does discuss 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.

The 100 mg here is another good dosage.

Vitamin B6

An ingredient that works to help the body make energy from food.

It converts it into glucose so it can, therefore, be used for energy. B6 also has links to boosting metabolism and the 5 mg is all you need for a good top up.

Vitamin B12

Another good ingredient, this time because it stops you from storing as much fat.

We can’t create B12 naturally so supplementing it is useful. This is particularly the case for vegetarians and vegans who might not find it as easy to get it into their diets. This is because common sources are fish, dairy, and meat.


Another ingredient that stops the body from storing as much fat. Zinc has also been shown to improve the mood of the user according to – this is useful if you are dieting and this makes you feel grumpy!

The 10 mg is a great dosage.


Another very effective ingredient.

Glucomannan is a dietary fiber that is an appetite suppressant. It absorbs water, swelling in the stomach which makes the consumer feel full. This is also what stops you from feeling like snacking in between meals.

The 500 mg is a big dosage that will be of great use.

Finaflex PX Pro Xanthine

Blueberry Powder

An ingredient that may be full of antioxidants but isn’t the most famous of fat burners. There is a study that was referenced by WebMD, conducted on rodents it showed how taking Blueberries may change the way the body stores and even processes glucose or sugar for energy.

For some, this might be impressive but here at CLM, we only rely on human trials. This makes it unconvincing in our eyes. Also, the dosage is not given.


An ingredient becoming more and more common in fat burners but it is largely considered to be unproven.

It has similar effects to caffeine and is a milder stimulant but there are even some studies that dispute this.

Most of the backing it gets is for increasing energy focus and mood. It is believed to have respiratory benefits as it has been shown to widen the airways.

The effects are thought to be longer lasting than Caffeine but are still milder in their potency.

There is a study that showed how it didn’t have any beneficial effects when it came to cognition and mood when compared to a placebo and Caffeine.

Also, the dosage is not given so we can see if it can even have the potential effects.


A trend is starting to form as this works in a similar way to Caffeine.

They have tried to cram this product full of stimulants it appears. Perhaps more Caffeine would have sufficed!

It can help the user to deal with stress which makes it more of a nootropic and there are plenty of those to come.

Without the dosage, we aren’t sure if it can even offer the above.

Rauwolfia Vomitoria

Not an ingredient you want to see in your fat burner.

It works in a similar way to Yohimbine This has potential side effects which really puts us off. actually says that there isn’t a lot known of Rauwolfia Vomitorias potency which is always a concern as well.

Some say it can offer fat burning potential but we don’t like to be test dummies in this respect.

The dosage is not given which just adds to the misery for this product really.


And so on to the mood enhancing blend we go.

This is an ingredient that might not actually help us to burn fat but it might have some uses.

L-Phenylalanine is believed to be able to help to elevate mood by synthesizing significant brain cells.

It is an amino acid and is found in a variety of proteins. The body actually converts L-Phenylalanine into tyrosine but technically, you could just find a supplement that gives you this directly.

It could have something to offer but without the dosage, we don’t know if it will.

Schisandra Chinensis

A traditional Chinese ingredient, this might have more than one benefit.

According to WebMD, it is described as a tonic that can reducing hunger, fatigue, delaying the aging process, increasing vitality, and improving mental health.

This sounds good but it doesn’t have a lot of support. WebMD even goes on to say that more research is needed to confirm whether products containing Schisandra with other herbs are safe and effective.

Hordenine HCL

An ingredient that works in a similar way to Black Pepper Extract in Instant Knockout.

Since it enhances the benefits of the other ingredients it would usually be a decent ingredient. The problem is, most of the other ingredients in Finaflex PX Pro Xanthine aren’t that great.


An ingredient we see a bit more of in nootropics, at least it has more research behind it.

It will help you to stay focused and alert. This is something that can complement a workout. Also, Huperzine A has been found to increase muscle strength. By blocking acetylcholinesterase it can help with muscle pumps.

A useful ingredient for cognition and protecting the brain. This might be good since there are so many stimulants in this product.

Instant Knockout vs Finaflex PX Pro Xanthine Side Effects

The easy place to start is with Instant Knockout. Their mix of natural, proven ingredients and safe and effective dosages makes it a good product in this area.

The same cannot quite be said for Finaflex PX Pro Xanthine. The combination of stimulants and proprietary blends is a bad mix. We need to know if there are safe amounts of each of these ingredients.

Also, the inclusion of Rauwolfia Vomitoria which works in a similar way to Yohimbine is a concern. Yohimbine has been found to potentially cause irritability, elevated heart rate, raised blood pressure and more.
