About the Company
Founded by two professional bodybuilders, Core Nutritionals is a supplements company that markets a range of products, from fat burners to pre-workouts.
This company prides itself on the quality of its goods, which are all manufactured in cGMP facilities in the US. Let’s see whether Fury Extreme can live up to their expectations.
The Ingredients and How They Work
It’s great to see a pre-workout that doesn’t hide its ingredients in any blends – so you can see the exact doses of each individual ingredient contained.
We can see positives and negatives when looking at its ingredient list. We’ll take you through each nutrient, so you can see how effective this pre-workout really is.
See for yourself:
This is a molecule capable of producing energy (ATP) rapidly when your body’s under stress (lifting weights in the gym). Ultimately, Creatine Monohydrate boosts strength and endurance, allowing you to push further than normal.
Core Nutritionals has dosed this ingredient well, so you’ll be sure to experience its full benefits – Creatine Monohydrate’s definitely worth looking out for when choosing a pre-workout supplement.
L-Citrulline’s an amino acid that turns into L-Arginine in your kidneys, which raises your nitric oxide levels. This leads to your blood vessels dilating (vasodilation), increasing blood flow, and resulting in intense muscle pumps while you lift weights.
But how do increased muscle pumps benefit you in the gym? Well, with more blood pumping through your muscles, you’ll experience a boost in endurance, strength, and even muscle protein synthesis (muscle gains).
L-Citrulline’s a key pre-workout ingredient, but there’s a problem with Fury Extreme – it’s been seriously under-dosed.
The optimal dose for this ingredient is 6,000mg-8,000mg, and Fury Extreme only contains 3,000mg. This means that the L-Citrulline in Fury Extreme might be ineffective.
We recommend that you search for a pre-workout supplement containing 6,000mg-8,000mg of L-Citrulline or Citrulline Malate (the latter is the more beneficial form).

Also known as Betaine, this molecule is believed to enhance endurance and strength, while reducing fatigue and body fat. But here’s the bad news – no studies have proven it works.
Not only that, studies have shown that it causes an unwanted side effect – trimethylglycine can cause fishy odors from your breath and body secretions.
It’s not worth suffering from this side effect, especially when this ingredient is ineffective in benefiting your gym session.
Extracted from L-Arginine by removing a carboxylic acid group (decarboxylation), Agmatine Sulfate’s believed to benefit your cognition.
It’s clear that Core Nutritionals has added this into Fury Extreme to boost your focus in the gym, but no human studies have proven that it delivers this benefit.
Not only that, but it’s only thought to improve cognition when taken in doses of 1.6-6.4mg per kg of body weight – this means an 80kg person would only need a dose of 128mg-512mg, and it’s been advised that you don’t take a larger dose than this.
As Fury Extreme contains 1,000mg of Agmatine Sulfate, this dose is past the recommended dose unless you’re 160kg.
Also known as NALT, it’s a form of L-Tyrosine that’s believed to be more soluble, meaning it would be more effective in lower doses.
However, this ingredient’s mostly used for it’s cognitive-boosting properties. For this reason, it’s more suited to a Nootropic, as it offers no specific benefits in a pre-workout supplement (like boost in strength, endurance, or energy).

This molecule’s most commonly found in the yolk of eggs, believed to improve endurance, cognition (memory and reaction time), and reduce fatigue.
However, here’s where the problems start. This ingredient can cause side effects in high doses – every individual has different tolerances, so we recommend you to try taking 50-100mg daily before increasing the dose.
As Fury Extreme contains 500mg, this could cause side effects in those sensitive to Choline Bitartrate – such as diarrhea, sweating, and fishy body odor.
But that’s not all. No studies have shown that this ingredient delivers any benefits at all, meaning it’s an ineffective ingredient in this product.
We recommend that you stay away from Choline to avoid any side effects, especially when you won’t experience any benefits to your gym session.
Caffeine’s a strong mental stimulant that offers numerous benefits, like enhanced strength and endurance, as well as cognition – all key benefits of a pre-workout supplement.
It’s perfect taken pre-workout, but the only problem with Fury Extreme is the low dose. We recommend consuming a 150-200mg dose to experience Caffeine’s full benefits – as this product only contains 100mg, it’s been slightly under-dosed.
However, make sure that your stay within a 150-200mg dose of Caffeine per serving when looking for a pre-workout supplement – a dose higher can lead to unwanted side effects like jitters and energy crashes.
Core Nutritionals has clearly done its research by including L-Theanine alongside Caffeine here – the two work in synergy to form a ‘smart-caffeine’, delivering enhanced benefits of Caffeine without risking unwanted side effects.
L-Theanine’s also been dosed perfectly in Fury Extreme at 200mg. We recommend that you look for a pre-workout supplement containing 100-200mg of L-Theanine alongside Caffeine, to experience the ‘smart-caffeine’ benefits.
This is simply a mixture of Pterostilbene and Caffeine, which is believed to prolong the effects of caffeine by 25%, and deliver more caffeine into your bloodstream by 30%. But this is a problem.
Fury Extreme already contains 100mg of Caffeine, so if this ingredient is capable of delivering 30% more caffeine into your bloodstream, this means you’ll have a total of 260mg in your system.
Why is this bad? Well, the recommended daily allowance (RDA) for Caffeine is 400mg, so taking anywhere near this in one dose can lead to side effects like jitters and energy crashes – which would ruin your gym session.
We recommend that you search for a pre-workout that contains 150-200mg of Caffeine, so you can assess your tolerance before increasing the dose to over 200mg per serving.

Found in Cocoa Extract, Theobromine’s a mild stimulant believed to be responsible for the boost you get from eating chocolate.
This is a problem. Theobromine actually heightens the effects of Caffeine, meaning increased risk of unwanted side effects like jitters and energy crashes.
We recommend that you avoid mixing large amounts of stimulants together, to avoid side effects and stay safe.
Bitter Orange Peel
Also known as Synephrine, this molecule’s most commonly seen in fat burner supplements – it’s proven to help reduce body fat.
However, here’s where the problems start. Fat loss isn’t a key benefit of a pre-workout supplement, and it’s known to have caused some serious side effects (high blood pressure, fainting, irregular heartbeat).
We strongly recommend that you stay away from Bitter Orange Peel to avoid any dangerous side effects.
This compound is believed to boost fat loss, but there’s been no studies to prove that it delivers this benefit.
This is a problem, as fat loss isn’t a key factor of a pre-workout supplement – there’s already top quality fat burners on the market, so there’s no need for a pre-workout to offer fat burning benefits.
Fury Extreme contains some key pre-workout ingredients, like Creatine Monohydrate, Citrulline, Caffeine, and L-Theanine. But the rest are ineffective or come with side effects.

Fury Extreme Review Conclusion
It’s a shame that Core Nutritionals has included numerous ineffective ingredients that come with risks of side effects in Fury Extreme – especially when they’ve included some key pre-workout ingredients (Creatine Monohydrate, L-Citrulline, Caffeine, and L-Theanine).
The worrying thing about Fury Extreme is the high amounts of stimulants, which can cause side effects, and the addition of Bitter Orange Peel, which is known to be potentially harmful.
We recommend avoiding dangerous nutrients, like Bitter Orange Peel, when choosing a quality pre-workout supplement. Look for products containing more key pre-workout ingredients, such as Beetroot Extract and Rhodiola Rosea.
