Instant Knockout Vs Hydroxycut Hardcore Next Gen Fat Burner Comparison Review

A real tasty battle for you today. With two of the better known fat burners on the market, we turn our attention to Instant Knockout vs Hydroxycut Hardcore Next Gen to see just who has the best fat burner.

It is always good to put two of the more popular fat burners against each other, surely whoever prevails here will do so as one of the best in the industry? Time will tell.

If you are looking to burn fat then you will want your supplement to do more than just that. A good fat burner should also:

  • Increase energy
  • Suppress appetite
  • Be 100% safe

The ingredients are where we will find out more about these areas but let’s just stop and say that neither of these products uses proprietary blends.

We always like to see a supplement that stays clear of these blends as it gives the user the chance to see if what they are looking to consume is both safe and effective. Too many companies hide their inferior dosages behind a blend, and some even have dangerous amounts of bad ingredients hidden away.

Thankfully that isn’t the case for either of these, so let’s get to know them both a little better.

Instant Knockout vs Hydroxycut Hardcore Next Gen: Who Makes These Fat Burners?

Roar AmbitionInstant Knockout Review

The team behind Instant Knockout is Roar Ambition, a supplements company making some real waves in recent years.

All their products are 100% natural which is part of the reason so many people are turning to them for their T-boosters (theirs is called TestoFuel) amongst other products.

They have a generous money back guarantee and they ship from the UK and USA, making their delivery quick and efficient. If we aren’t enough to convey their good reputation then maybe you would trust the opinion of pro athletes. UFC fighter Diego Sanchez is just one of the names they have as part of their endorsement roster as he uses the product to make weight.

If it is good enough for the pro athletes who are tested as part of their job, then it must be doing something right.


The people who make Hydroxycut Hardcore Next Gen are MuscleTech.

They actually went bankrupt back in 2006 and were consequently bought out by Iovate Health Sciences who still use the old brand name to this day.

They have a real vast catalog of products and these including everything from protein cookies to whey protein.

Not short of self-confidence their website says they offer “Superior Science. Superior Results”  and this is possibly why they are proud to say they make their products in the USA and manufacture to the cGMP standards which is always reassuring.

Going by when we have looked at their products in the past, they are known to change their formula so as always we strive to bring you the latest version.

Their products are found everywhere around the world it seems. Such is the reach of their brand, so let’s see if this results in a good and effective fat burner.

Instant Knockout vs Hydroxycut Hardcore Next Gen Ingredients

So, no proprietary blends in sight – Great news! Let’s take a look at the label and see what each of these fat burners has to offer.

Mutual Ingredients

Green Coffee Extract

A good inclusion from both products here since this is good at affecting the glucose levels in your blood – resulting in your body using fat, burning it for energy.

It will also stop you from actually absorbing fat at the same rate by stimulating your fat metabolism. Out with the old fat and no entry to the new.

The optimal dosage is around 120 – 300 mg of this ingredient and although Instant Knockout is very close to this with 100 mg, the 200 mg in Hydroxycut Hardcore means the user will benefit more.

Caffeine Anhydrous

This is an important section for both fat burners. Too much caffeine can result in some unwanted side effects such as headaches and jitters.

With this in mind, you really want either a very sensible dosage, or a caffeine consumption that is spread out throughout the day.

The 300 mg in Instant Knockout is spread over 4 capsules taken at different times of day. Meaning you should be free from unwanted side effects.

However, Hydroxycut Hardcore has almost double the caffeine and spread over only two servings. This for us is too much caffeine all at once.

Instant Knockout vs Hydroxycut Hardcore Next Gen Individual Ingredients

Instant Knockout

Green Tea Extract

A staple ingredient in many fat burners, and for good reason. The catechins contained in Green Tea Extract help your body to get the thermogenic process going. This is where an ingredient heats you up inside. In turn your body actually burns fat cooling itself down.

The benefits are limited to this alone, it is also good at restricting the amount of fat your body actually takes on so it burns what you do have as well as slowing down the amount you put back on.

It even compliments your exercise efforts to use fat for fuel which is exactly what you want. 500 mg is everything you need here.

Cayenne Pepper Extract

Another great thermogenic ingredient, you will find many of these in a good fat burner. This, in particular, is a good inclusion. Not only does it help your body to burn fat but it also suppresses appetite.

That’s right it will make you feel fuller for longer so you are less tempted to reach for an unhealthy snack in between meals.

100 mg is another optimal dosage.


Another great appetite suppressant, Instant Knockout really want to help you burn fat and stop you from putting it all back on it seems.

This works by swelling in your stomach and making you feel as though you don’t need to eat, it is often found in Asian cuisine.

Hydroxycut Hardcore Next Gen

Blue Skullcap Extract

Sounds funny for sure, but this is actually a member of the mint family.

It might be better placed in a nootropic as its main uses are more for anxiety and it can even help you to sleep. It is likely that this has been included because of the high caffeine content. But we don’t feel it will be enough to counter such a high level of caffeine.

Yohimbe Extract

This is a type of bark that is often used in ancient medicine as an aphrodisiac.

This is where it has made its name and the evidence to support its use for sexual health has been proven over the years. However, it is a relatively new ingredient in the world of fat burners. So its uses are uncertain, although it is thought to help to encourage thermogenesis in the body.

This doesn’t come without its risks though. Studies have shown that it can result in spikes in blood pressure and heart rate. The dosage in Hydroxycut is above the recommended daily allowance. Be wary of this!!

Instant Knockout vs Hydroxycut Hardcore Next Gen Side Effects

This is where you can take a chance on Instant Knockout and it will be risk-free. There are no known side effects of using this product. It uses only natural ingredients in sensible and effective dosages.

The same can’t be said for Hydroxycut Hardcore, unfortunately. Not only is the caffeine level way to high for what we like to see. There are also potential side effects from different ingredients like Yohimbine. Anything that raises blood pressure, as well as heart rate, should be treated with caution.

You should definitely not take this alongside any other supplements that contain caffeine.

Instant Knockout vs Hydroxycut Hardcore Next Gen Conclusion

Winner: Instant Knockout

Instant Knockout Review

For us, there is only one winner here and that is Instant Knockout. Its mix of safety and effectiveness is something that we actually don’t come across as often as we would like in the supplements world.

It is certainly one of the best fat burners we have seen and you will find it hard to beat. There are so many key fat burner ingredients that not enough supplements use.

Hydroxycut Hardcore started well, it does contain some very useful ingredients. But we don’t know why they use so much caffeine. Unless they are trying to compensate for the rest of the ingredients.

You are likely to feel a difference when using it, but that might just be your heart rate!
