I am NOT a doctor so please take my review as you will, and these are just my own thoughts and experiences with this product. With that being said, I hope you find this information useful.

Core Nutritionals Peak Xis one of the many unique products we carry here at NutriFit. What is Peak X? Peak X is a non-stimulant (no caffeine) pre-workout formula.

The great thing about this product is it’s perfect for night time training, a simple morning ‘pick me up’ or you can even stack it with your favorite stim pre-workout for CRAZY results. So, what makes Peak X so unique? This product includes a total of four patented ingredients! Generally, if something is patented it works right? So, let’s take a closer look into each of those ingredients and how they will benefit you.


Peak02 includes six organic mushroom strains such as Cordyceps, Reishi, King Trumpet, Shiitake, Lion's Mane and Turkey Tail. It is a blend of adaptogens, which not only help with recovery but mental clarity as well. Some studies have shown that 28 grams of Peak02 is necessary for the effects to even be present. With Peak X you’ll be getting 28 grams in a fourteen day stretch with one serving per day at 2,000mg. It is critical to consistently consume Peak02 each day to build up to the 28g for maximum benefits.


Nitrosigne is a compound of arginine and silicon. This ingredient is shown to increase blood flow and more blood flow during workouts for maximum delivery of oxygen and nutrients to the working muscle. Studies have shown that after fourteen days of using Nitrosigine it will increase the effects of the proteins in the body by an average of 50% in turn leading to cardiovascular health, increased blood flow and a rise in nitric oxide levels. It is suggested that you consume 1,5000 milligrams of Nitrosigine per day for maximum results and that is exactly what is in a serving of Peak X.


VASO6 is a compound of 6 molecules from both green tea and grape seed extract. The compound is used to increase blood flow throughout the whole body resulting in higher nitric oxide levels. The compound will deliver high energy and power for training, some studies have also shown that it helps with mental performance as well. There are also some studies showing it increases glucose uptake in the body as well as protein synthesis. The suggested dosing for VASO6 is 300 milligrams per day and again, that is exactly the dosing in one serving of Peak X.


ElevATP is a proprietary blend of apple extract and ancient peat. Many pre-workouts will have this ingredient for a couple different reasons. This blend essentially stimulates the production of ATP in the body leading to a huge increase in energy. Studies show that after just one use of ElevATP, blood levels have increased by almost 40% which will lead to increase in training levels and endurance. It has been compared to creatine with many of the same benefits. Studies have shown just 150 milligrams is required for optimal results, but Peak X took it a step further and offers 300 milligrams per serving, twice the recommended dosage.

To make this product different than most non-stim pre-workouts, Core Nutritionals decided to put 3,200 milligrams of Beta-Alanine on top of all the unique ingredients. The Beta-Alanine will provide greater endurance, and possibly a "tingly" feeling that most users like. Being non-stim, it's unlikely anyone using this product will "feel" any sort of buzz or kick. But, with the Beta-Alanine the tingly feeling will still make you feel like the product is working.


Peak X is currently one of our top-selling non-stim formulas and I have personally used a full tub. I added it to other stimulant pre-workouts for the blood flow, and pump benefits, but to also have the Peak02 in my system.

I highly recommend this product if you are looking for something new in the pump category, or want to make your current pre-workout more effective.
