Instant Knockout vs Vexxum Review

What is it you want from a fat burner? Appetite suppressants? Thermogenics? Energy enhancers? Our Instant Knockout vs Vexxum Review will give you all the details needed to help you find the supplement you need.

A good fat burner is more than just that, it should be able to help you burn fat around the clock and be completely safe whilst it does it.

You want it to really help you to show off your physique and help you get a body you are proud of. Those abs aren’t going to appear out of nowhere!

You can get the body of your dreams, but with a little help along the way you can get there quicker. That is why it is important to get a supplement that has proven ingredients.

Too many fat burners just pack their product full of stimulants to make the user feel like there is a difference, but there is often little substance behind this.

Time to see which of our products today can actually back up what they say on their label.

Instant Knockout vs Vexxum: Who Makes These Fat Burners?

Roar Ambition

The people behind Instant Knockout are Roar Ambition.

These guys are based in the UK but ship worldwide directly from the USA and UK.

They have a great reputation for customer service since they have a generous money back guarantee that really gives the user the chance to try their products.

They also review and amend their ingredients and dosages regularly. This ensures the customer is getting the best possible version of their product.

In terms of endorsements, theirs are pretty impressive. UFC fighter Diego Sanchez uses Instant Knockout to make weight before a professional fight.

With so many positive reviews on YouTube and across the web, they are one of the most popular brands we have seen.

Pro Supps

Vexxum is from the people at Pro Supps, a large US-based supplements company.

With a wide reach, they have strong branding and recognizable products. These range from protein cookies and all things on the go as well as pre workouts and beyond. If merch is your thing then they also have a wide range.

Their website is rather simple but we couldn’t find anything regarding a money back guarantees when we had a quick look.

Instant Knockout vs Vexxum Review of Ingredients

Now we get to really take a closer look and find out which is the most effective fat burner.

We noticed straight away that Vexxum use one big proprietary blend. This means we don’t get to take a good look at what goes into each capsule and means the simulants here do not have their dosages revealed.

Potentially dangerous but we will get what we can from it.

There is also the serving suggestion which could do with being amended really. They have tried to really condense each serving but the one capsule a day means the effects are unlikely to be felt throughout.

We prefer to see an approach like Instant Knockout which means the benefits are spread out over 3-4 servings.

Since the only mutual ingredient is Caffeine Anhydrous we will start with that.

Caffeine Anhydrous

A good inclusion for both as this is a quality caffeine that will work by getting your metabolism going.

Because of this you will be burning fat for energy.

It will give you a boost so if you are using a fat burner alongside a lower than usual calorie intake, this is the type of ingredient you need.

We are worried about the fact that Vexxum has it in their blend, but the 627 mg total blend for each capsule means it is unlikely that there is too much of it.

The 350 mg in Instant Knockout is a sensible dosage that will really benefit the user.

Individual Ingredients

Instant Knockout

Green Tea

A great fat burner ingredient that is found in the best supplements going.

More than a popular tea time drink it contains antioxidants EGCG which is known to get your metabolism going.

It can even enhance your endurance during exercise helping you to extend yourself and burn more calories along the way.

It’s surprising that Vexxum did not include this since they claim to be a thermogenic enhancing product and this is one of the best going. It heats your body up from the inside, causing it to burn ft to cool itself down.

Cayenne Pepper

Another proven thermogenic ingredient, the natural ingredients are really the most effective here.

A great way of getting the many benefits of this spice is through supplementation, especially if you are not into the heat!

Getting cayenne pepper into your diet is proven to suppress appetite which is the sort of trait we are on the search for here. Anything that stops you from reaching for the snack in between meals is exactly what you need.

The dosage of 100 mg is optimal for fat burning.


Another great fat burner and this dietary fiber swells in your stomach to make you feel full.

This is another appetite suppressant and we like it because again, it is natural.

Because it absorbs liquid it is effective and the sort of ingredient you should be on the hunt for. The 500 mg shows that Instant Knockout knows how important and effective it is.


Caffeine Citrate

Apart from the proprietary blend, we also noticed that Vexxum has a lot of stimulants in there. Here is another and although this is thought to less potent than caffeine, it is faster acting.

It would be good if, by the end, Vexxum had a wide range of different fat burner ingredients to really give different benefits to the user. We’re not sure how effective this abe anyway since it is part of the proprietary blend.

Yohimbe Bark Extract

A bit of a different approach we have left out some of the stimulants in this product as there are so many. It is thought to be a decent thermogenic but the fact that it has some side effects means we can’t really get behind it.

It is thought to elevate blood pressure and heart rate as well as headaches and stomach upset which isn’t great since we have no idea how much of it there is in this product.

Hordenine HCL

It could be a decent ingredient since although it doesn’t directly boost your fat burning capabilities, it can enhance the benefits of the other ingredients.

This would be good if the ingredients were proven fat burners, but it seems that this product is just crammed with stimulants really.

Since it is in the blend, we can’t say just how good it could be.

Instant Knockout vs Vexxum Side Effects

The good news is that Instant Knockout only contains sensible doses of stimulants and all ingredients are 100% natural so the risk of side effects is very minimal.

With Vexxum, there is the proprietary blend and a lot of stimulants. Although, the blend isn’t a high overall dosage anyway so this should be fine.

We would never recommend a product like Vexxum that contains Yohimbe as the side effects such as elevated heart rate and blood pressure really put us off, even if the dosage is likely to be too low to really concern you.

Instant Knockout vs Vexxum Review Conclusion

Winner: Instant Knockout

(Clean Lean Machine tip: Get 1 box free when you buy 3 boxes!)

Although Vexxum is made by the bigger company, David convincingly slew Goliath here. That is being unfair to Instant Knockout though as it is a great product that is really popular.

It has so many proven ingredients that are natural and although it has a couple of stimulants, it doesn’t rely on them and their dosages are optimal.

Vexxum is another fat burner just like many of the rubbish we often see, it is packed full of stimulants that won’t actually do a lot for your fat burning.

This is why Instant Knockout is so good, it does everything right, thermogenic, metabolism boosters and appetite suppressant and energy increasing ingredients, need we say more?
