PEAK X… a new category of supplements?

Is it a Pump formula? Is it a Non-stimulant pre-workout? What exactly is PEAK X? Core Nutritionals, being the creators of this product, have called PEAK X a “Non-stimulant Peak Performance and Pump Optimizer”, which we can all agree, is open to interpretation. What we do know is we are looking at a very interesting product. 5 ingredients, 4 patented ingredients, no stimulants, focused around performance and pump!

Ingredient Breakdown:

Beta Alanine

Beta Alanine is a non-essential acid; meaning we can synthesize this amino within the body and it is not essential to consume from our diet. Beta Alanine is the precursor to carnosine which is a molecule we store within our muscles to help flush out acids, such as lactic acid, when required. This flushing of acids prevents their build up which therefore delays the onset of muscular fatigue and increasing muscular endurance. Beta Alanine is most known for the ‘tingling’ sensation users get, known as paresthesia. This sensation is perfectly normal and does lessen with consistent use.

Dose p/serve: 3.2 gram of Beta Alanine

Recommended dosage: 3.2 – 6.4 grams of Beta Alanine

PeakO2™ [Cordyceps militaris (Cordyceps), Ganoderma lucidum (Reishi), Pleurotus eryngii (King Trumpet), Lentinula edodes (Shiitake), Hericium erinaceus (Lions Mane), and Trametes versicolor (Turkey Tail)]

PeakO2™ is an organic-certified combination of six Ayurvedic mushroom strains. These mushrooms are powerful adaptogens, which allow athletes to “adapt” to and overcome physical and mental stress, giving you the extra edge you want to take your training to the next level. PeakO2™ is brought to us by the ingredient masterminds over at Compound Solutions. PeakO2™ has been shown to boost both endurance AND power, it’s a real powerhouse ingredient.

Dose p/serve: 2 grams of PeakO2™

Recommended dosage: 1 – 2 grams of PeakO2™

Nitrosigine® (Inositol arginine silicate)

Nitrosigine® is a patented complex of arginine, inositol, and potassium silicate brought to us by Nutrition21. Nitrosigine® is more biologically effective than arginine HCL, so much so that is has been shown to result in almost 5x greater blood vessel relaxation when compared to Arginine. Of course, increased vasodilation will result in increased muscle pumps, increased nutrient delivery. Nitrosigine® really impresses with its ability to show results in under 15 minutes after consumption, with benefits still be experienced up to 6 hours after consumption. Also, studies have shown the benefits of Nitrosigine® on improving cognition, focus, processing speed & mental flexibility.

Dose p/serve: 1,500 mg of Nitrosigine®

Recommended dosage: 1,500 mg of Nitrosigine® was the studied dose.

Vaso6™ [Green Tea Extract (leaf)]

Vaso6™ is a Green Tea extract standardized for only the most effective blood flow enhancing fractions specifically to promote vasodilation, therefore, resulting in much greater production of Nitric Oxide, as well as increased nutrient and antioxidant delivery. Increased muscle pumps, recovery and performance have also been documented. 300 mg’s of Vaso6™ has been studied to result in 10x more vasodilation than 7,000 mg’s of Arginine.

Dose p/serve: 300 mg of Vaso6™

Recommended dosage: 300 mg of Vaso6™


ElevATP® is a combination of a water extract of “ancient peat” (fossilised plants) and apple extract that works with our natural energy-producing mechanisms to stimulate the production of ATP. Studies have shown a 150mg dose of elevATP® to increased cellular levels of ATP in the body which has then resulted in increased strength, increased power output, improved performance & training volume in resistance trained athletes.

Dose p/serve: 300 mg of elevATP®

Recommended dosage: 150 mg of elevATP®

The Formulation:

Quality over quantity is the first impression we get from PEAK X. 5 ingredients, with 4 being patented/ trademarked ingredients, there’s no doubting you are getting the best of the best with each serve. And with that, the dosing of these 5 ingredients is second to none! Clinical beta alanine, clinical PeakO2™, clinical Nitrosigine®, clinical Vaso6™ & double clinical elevATP®.

Let’s break the formula down and see what we’ve got going on:

Beta Alanine – Endurance, Power Output

PeakO2™ – Oxygen Uptake, Endurance, Power Output

Nitrosigine® – Vasodilation, Nutrient Delivery, Cognition/ Mental Flexibility

Vaso6™ – Vasodilation, Nutrient Delivery

elevATP® – Power Output, Strength

We should disclaim that these are not the only benefits these ingredients will provide. Vaso6, for example, while performing as a vasodilator and therefore increasing nutrient delivery will also have an effect on improving anaerobic peak power as well as extending time-to-exhaustion through the additional effects of increased nitric oxide levels. We can see how there is a lot of overlapping effects from the 5 ingredients in PEAK X.

That being said, with this overlapping, the formula has been very well thought out to work INCREDIBLY well together. All the ingredients in PEAK X compliment each other but working towards the same end result BUT by using different pathways and reactions within the body. It’s really quite a beautiful thing to visualise when you break down each ingredients role.

We did mention it before but it cannot be skimmed over. PEAK X uses the best of the best when it comes to the ingredient choices. Every ingredient has multiple studies behind the effects and with that comes a great sense of confidence that this product will deliver on what it claims to do.

Taste & Consumability:

You’ve got 3 flavours of Core Nutritionals PEAK X, and no surprises here, they match up with the 3 flavours of Core Nutritionals stimulant based pre-workout, FURY X. Australian Gummy Snakes, Pineapple Strawberry and Star Candy are your flavour options. In this 10.5 gram serve you are going to get yourself 70% active ingredients and 30% flavours, stabilisers and ‘fillers’.

Let’s get straight into it, even with the 30% of extra’s, PEAK X doesn’t taste amazing. It’s by no means a bad flavour, in fact, the flavour is actually pretty nice. It’s just, no matter how much flavouring you use, you won’t be able to mask these 5 ingredients at these dosages. And those 5 ingredients bring an underlying extract taste and texture to this product that isn’t the most enjoyable.

Even when stacked with a stimulant based pre-workout, no matter how incredible that pre tastes alone, the ‘extracty’ component of PEAK X will still come through. All this being said, is this flavour going to stop us from using it, absolutely NOT! We know some people are really fussy with flavours but this product is here for the ingredients and the ingredients alone, if it wasn’t a 10 gram serving size I’m sure Core would have put this into capsules.

Actual Effects:

Here’s what you are most interested in… What does PEAK X actually do? What will I feel from PEAK X? How will PEAK X benefit me? Going back to the beginning of this review, Core Nutritionals refer to PEAK X as a ‘“Non-stimulant Peak Performance and Pump Optimizer” supplement.

“Non-stimulant Peak Performance”

PEAK X contains no stimulants, no caffeine, nothing, so it’s safe to confirm that it is indeed a non-stimulant product. As for the “Peak Performance”, this is where things get interesting. Have you ever taken a pre-workout or even just had a workout where you feel ‘good’… and by ‘good’ I really mean amazing? Physically you feel fresh, strong, alert, the weights are moving, the muscles are contracting and you find yourself in the best positive mindset from the first set through to the last.

This is what PEAK X delivers day after day, session after session. The increase in physical performance experienced within our first 3 weeks of using PEAK X was nothing short of amazing, so much so we are questioning how and why consistently. New PR’s in the gym, recovering faster from set to set and workout to workout, fuller muscles than ever experienced (but we will talk more about that soon) and even aerobically, feeling fitter, fresher and faster which each day. Metcons, walks, runs, cycles, F45 sessions were all being hit harder and harder but still feeling more comfortable throughout them.

“Pump Optimizer”

PEAK X delivers one of the best muscle pumps we have experienced, there, we said it! We never thought 2 pump ingredients could be so effective, but to be fair, you can argue the others ingredients do help a little as well. The best thing about the pump from PEAK X is that it is a true blood volume pump. The mass increase in NO resulting in greater blood flow to the working muscles and with that bringing one serious muscle pump that also hangs around well after the session is done.

But what about us sports athletes? I don’t want a muscle pump in my legs as I’m running around, sprinting, jumping & kicking. The incredible pumps we experienced was purely from weight training sessions, focusing on tension, contractions and stretching. When we put PEAK X to test aerobically, the benefits of the increased nitric oxide levels came in the form of some serious vascularity increases. So much so we had veins popping up in our quads and calves we hadn’t seen before.

It goes without saying, we have been impressed by the effects from PEAK X. The consistent benefits in performance for the cost of 1 coffee a day, PEAK X is going to stay a consistent part of our daily supplement routine.


This is where PEAK X can really show off its versatility. Let’s break down the few ways to stack and utilise PEAK X’s formula. We should mention, we tested PEAK X as a stand-alone product AND also stacked with various stimulant and non-stimulant products.

With a High Stimulant Pre-Workout: If you are wanting to add PEAK X to a high stimulant pre-workout for improved pump and performance you have nothing to worry about. Even if the pre-workout you use contains any of the ingredients in PEAK X, they all can be taken in larger doses safely. VASO6 has been studied safely in doses up to 1,200mg per day & Beta Alanine needs a dose between 3.2 – 6.4 grams per day. It should be noted PEAK X stacks perfectly with FURY X from Core Nutritionals, no surprises there.

With a Pump Formula: If you’re wanting to create some kind of non-stimulant pump Frankenstein product then PEAK X is for you. Once again you have nothing to worry about with the VASO6 and Nitrosigine as both have been studied safely in doses well above the clinically recommended dose in PEAK X. Find yourself a formula that uses Glycerol, Agmatine, Norvaline, Citrulline & Nitrates; pair that up with PEAK X and get ready!

With a Nootropic: If PEAK X brings the BEST physical performance and pump we have experienced; then the only thing missing from it being a complete stimulant based pre-workout is stimulants and focus, even though Nitrosigine has been shown to increase mental flexibility in athletes. Stacking PEAK X with your favourite nootropic formula could be a way to make yourself a focus driven complete pre-workout with some ridiculous performance benefits.

What’s The Verdict:

So, what is PEAK X? It’s more than just a pump formula, it really brings a new angle to what we know as ‘Stimulant Free Pre-Workouts’. With a formula we cannot fault for any ingredients or any dosages, Core Nutritionals have really put together something very special. If you are serious about improving your performance whether it be in the gym, in a sport, or just physically stronger, fitter and faster; then you need to make Core Nutritionals PEAK X a part of your life. We know we will be.
