Cannibal Inferno Fat Burner

PRODUCT REVIEW: Cannibal Inferno Fat Burner

Here we’re taking a look at the brand new Cannibal Inferno formula for 2020.

It’s an update from their old formula which was released way back in 2013. Stimulant-packed, aggressive, and relentless. Those are the three adjectives that we’d give to Cannibal Inferno. According to the producers, it will “turn your body into a raging bonfire of thermogenesis.”

Obviously, this supplement isn’t aimed at folks who’re new to fat burners. It can catch you by surprise when you take it, and not in a good way!

However, before jumping to conclusions too early. Let’s look through the ingredients, side effects, and benefits in this Chaos and Pain Cannibal Inferno review. Afterwards, we’ll tell you if we recommend it as one of our top fat burners.

Pros and Cons


  • Gives you ample energy
  • Stimulant-based, it can serve as a pre-workout too
  • Open sourced formula


  • Potentially unsafe – uses high amounts of stimulants
  • Only for the most experienced users who can tolerate side effects
  • Missing a few core ingredients

Who Makes This Fat Burner?

Chaos and Pain is a company that’s been around for a number of years. They have a reputation for producing some of the most aggressive supplements on the market. When you check the ingredient formula in their Cannibal Inferno fat burner, it will be easy to see where the rep comes from.

Claimed Benefits

  • Increased Energy
  • Enhanced Thermogenesis
  • Weight Loss Support


The ingredient formula in Cannibal Inferno is fully transparent. You can see everything, including the dose of each ingredient.

However, we were a bit shocked by some choices in this fat burner. Not only do they bring potential side effects but their dosages are also very high.

See for yourself:

Acetyl L-Carnitine (650mg)

It can promote mental clarity, but isn’t proven to help with fat loss.

L-carnitine was a popular compound in fat burners back in the day. However, recent studies show that carnitine isn’t that great for fat loss. It can only work when you’re deficient in it, which is hard to be, as your body makes its own carnitine. Acetyl L-Carnitine is a more bioavailable source of this ingredient, and it comes with some unique cognitive benefits. Making it a better suited ingredient for a nootropic supplement. (1)

Caffeine (300mg)

Extremely high dosage of caffeine, not recommended unless you can tolerate it.

That’s a lot of caffeine per serving! We don’t recommend taking this much. Especially if you drink your regular coffee on top of this. Caffeine side effects include anxiety, insomnia, heart palpitations, high blood pressure, and more. However, if you can tolerate lots of caffeine, then it could very well work for you.

Grapefruit Powder

Slows down the metabolism of caffeine from your body, prolonging its effects.

This ingredient isn’t here to help you burn fat. At least not directly. Grapefruit powder is included because it makes it harder for your liver to process compounds like caffeine, so they stay longer in your system, and their effects are potentiated. We’re not sure how smart this is considering that Cannibal Inferno already contains a high amount of caffeine. There’s no need to make it any stronger!

Green Coffee Bean Extract

Natural carb blocker, helps you absorb a little less food than you eat.

This is a great ingredient. It contains certain compounds that are shown to slow down the absorption of carbs in your gut. As such, it can help to prevent fat gain. (2)

Synephrine HCl

Potentially dangerous stimulant.

According to WebMD, this is an ingredient you may want to avoid. This is a compound found in Bitter Orange Peel, and is known to cause side effects linked to the cardiovascular system. Make sure to check with your doctor if you have any kind of medical condition before taking this ingredient.


Helps regulate your blood sugar levels.

Good choice by Chaos and Pain Cannibal Inferno. Chromium is a trace mineral that supports your body in many ways. Specifically, the biggest benefit in the context of this review is that it can help regulate your blood sugar spikes after eating food. (3)

Grains of Paradise Extract

We don’t rate it as one of our top fat burning ingredients.

Until more evidence comes out, Grains of Paradise won’t be among our favorite ingredients for fat burners. It apparently has some weight loss properties, but the studies don’t look very convincing at the moment. (4)

Ginger Extract

Helps with nausea and promotes blood flow.

Ginger is a plant with many health benefits. It reduces inflammation, improves circulation throughout your body, and helps with stomach problems. All in all, it’s a solid supporting ingredient.

CapsiAtra Sweet Pepper

Triggers the metabolism to burn more calories.

This ingredient belongs to a group of so-called ‘thermogenics’. This is simply a term for natural compounds that stimulate your body’s metabolism, making it burn a bit more calories. (5)

Yohimbine HCl

Known to cause irregular heartbeat, kidney problems, and other side effects.

Yohimbine is another ingredient on our to-avoid list. It comes with a whole host of side effects, much like Synephrine. WebMD states that Yohimbine too is possibly unsafe.


Raises carnitine levels in the body, might help with fat loss slightly.

This is not a bad choice. ProGBB can support weight loss in two main ways. One, by raising your blood carnitine levels, which can potentially help your body tap into its fat stores for fuel. (6) And secondly, by promoting thermogenesis, the process where your body heats up from the inside.

Anything Missing?

Cannibal Inferno has some good ingredient choices, but a few ingredients should be added, such as Garcinia Cambogia which suppresses appetite. In addition, we’d like to see a few ingredients removed from the formula to make it safer.

How to Take (Dosage)

Cannibal Inferno dosage is 3 capsules once per day. However, we’d suggest starting with just one capsule due to this product’s potential side effects.

Side Effects

A number of ingredients in Cannibal Inferno can increase the risk of side effects. One of them is Bitter Orange Peel (aka Synephrine). WebMD states:

“Bitter orange is POSSIBLY UNSAFE when taken as a supplement for a medical purpose such as weight loss. Bitter orange, taken by itself or with stimulants such as caffeine or caffeine-containing herbs, might increase the risk for high blood pressure, fainting, heart attack, stroke, and other severe side effects.” –

This is on top of high amounts of caffeine, yohimbine and other stimulants in Cannibal Inferno that are also known to cause side effects.

Price and Value For Money?

30 servings of Cannibal Inferno will cost you $39.99 on the official website. If you like aggressive fat burners like this one, then it’s not a bad value for money.

Conclusion on Cannibal Inferno Review

So, should you buy Cannibal Inferno? It depends on what you’re looking for, and whether you’re willing to risk side effects.

If high dosages of caffeine alone no longer tickle you, then it might very well work for you.

But for most people, this will be a too aggressive fat burner. You can find much safer options that can give you better results in terms of fat loss.
