Fighters Core have hit the ground running this year, with a fat burning and muscle sparing formula that’s widely regarded as one of the best and most innovative at the moment.

Trying to retain as much muscle mass as possible when going through a cut can seem impossible. Lowering your calorie intake whilst training leaves you feeling drained, and means you can’t train at full capacity

It also means you don’t have the sufficient calories and protein intake to build muscle.

2020 has been a pretty grim year by all measures, but maybe it is about to get a little better. Well known supplement manufacturer PFX Labs have revealed their newest cutting supplement that has been designed for a 30 day cut, getting rid of unwanted fat whilst retaining muscle.

So … is this where Fighters Core becomes your new best friend? We find out.

Fighters Core

Product Overview

Fighters Core aims to be the ultimate blend for bodybuilders and physique competitors that are looking to shred and maintain athletic performance.

It promises the holy grail of serious bodybuilders. A no compromise approach to training without feeling fatigued during a fat loss phase.

Fat burning cornerstones caffeine and green tea have been included to accelerate your metabolic rate and keep your body in fat burning mode.

HMB has been included to retain as much muscle as possible during a cutting phase.

Teacrine has been implemented into the supplement to ensure you can fight fatigue and stay alert, with improved cognitive function.


Fighters Core come in 3 different bundles, the 30 Day Cut, or bundles of 60 and 90 days.

Each tub comes with 90 capsules, to be taken 3 times daily for maximum results.

The Blend is Nigh

Everything is right there on the side of the tin, no proprietary blends.

All of the ingredients have been clearly listed with the amounts that have been carefully selected to give you the best results with no unwanted side effects.

Which let’s us know exactly how it will perform.

Ingredients Breakdown

You probably want to know exactly what goes into the Fighters Core supplement right?

There are 8 key ingredients that have all been included to do one of these two things:

  • Burn unwanted fat
  • Preserve muscle mass

So at least the goals are uncomplicated, even if the mechanisms through much they are achieved are not.

You’re training for bodybuilding or competing, so if you’re training hard and frequently, you’ll need a considerable calorie intake in-order to maintain muscle mass. Muscle requires a higher amount of energy to maintain.

Fighters Core will keep the metabolism high so you can continue to burn fat, whilst also using key ingredients such as HMB to protect the muscles from depletion and possibly even improve protein synthesis.

You don’t need to be taking one supplement for fat loss and a separate for muscle maintenance, instead it all comes in one tidy package.

Individual Ingredients

Chromium Picolinate

Struggling to keep hunger at bay whilst in a calorie deficit?

Chromium picolinate can help decrease your appetite. An 8 week study found that the mineral reduced food intake and cravings in the group.

Chromium picolinate improves the way the body uses insulin and as a result, supplements can help to improve blood sugar levels, something that is essential for health.

Calcium HMB

By far one of the most important ingredients when it comes to retaining muscle mass.

HMB is known as a supplement that preserves muscle and can potentially improve protein synthesis, essential for bodybuilders wanting to maintain mass during a fat loss phase.

Research has highlighted that supplementing with HMB before and after a training session might help prevent muscle damage and therefore a decreased chance of injury.

Green Tea & Caffeine

Almost all fat burning supplements have green tea as one of their main ingredients as it is known to boost the metabolic rate. The caffeine in green tea has the ability to potentiate fatty acids in the body and use them for energy, in the same way we usually use carbohydrates.

Green tea is also used to improve insulin sensitivity and reduce blood sugar levels. Essential for any athlete wanting to reduce their appetite.

Coleus Forskohlii Extract

This name may not be known to you, however you’ll learn to love it when you’re losing fat to compete.

The extract can free fatty acids from the body’s cells which can then be burned as fuel.

This means that any extra fat being held is then used as a fuel source. When the body uses these fatty acids, it may reduce the percentage of fat and therefore affects your lean muscle mass.


This chemical has similar properties to caffeine as it is used as a stimulant in the body. It is naturally occurring and is mainly used to fight fatigue and improve cognitive function as it stimulates the central nervous system.

What does this mean for your training?

During a fat loss phase, it is easy to feel fatigued due to a lack of calories which can result in less effective training sessions. Theacrine can be useful to push your body even harder during your workout so that you can focus on gaining strength and retaining muscle throughout this phase.


This is another ingredient that boosts the metabolism and aids weight loss, something necessary for physique athletes.

A study showed that women who ate a chili containing capsaicin (the main ingredient in capsimax) raised their metabolic rate for 30 minutes after consuming it. It is possible that capsaicin is a thermogenic chemical and allows the metabolism to increase whilst decreasing your appetite.

Fighters Core Side Effects

Given the ingredients that have been included and the dosages, we do not expect users to experience side effects.

Final Verdict

PFX Labs have taken the supplement game to a whole new level with Fighters Core. No longer will you feel depleted and fatigued whilst going through your cut.

Burn fat faster and efficiently – this is a supplement for anybody wanting to be lean but retain muscle.

If you’re willing to spend a bit of money on a supplement that does the job that two separate supplements normally do, then this is where you should be investing your money.
