Unleashing the Fury: A Look at Core Nutritionals' Next-Level Pre-Workout Formula - Core Fury V2

by Josh Davis

What is one thing that athletes in all sports at all levels have in common? We continuously strive to improve and push ourselves to our limits, every time we step foot in the gym or on the field. Core Nutritionals understands this mindset and has taken it to heart in reformulating their already innovative and revolutionary pre-workout supplement, Core Fury, into an absolute goliath formula. This new and improved pre-workout, Fury Version 2, is more than just a successor to its predecessor, which already set a new standard for innovative pre-workouts.

If you're wondering how Core Nutritionals could have possibly made this pre-workout even better, you're not alone. We were skeptical too, since Fury was already a complete powerhouse pre-workout formula, but they did it by taking all of the "core" ingredients from the original formula that have a massive amount of clinical research and indisputable efficacy, and using them to create a substantial base for Fury Version 2. These core ingredients include Beta-Alanine, Betaine Anhyrous, L-Taurine, L-Tyrosine, L-Citrulline, Alpha GPC, and Caffeine Anhydrous. Just having these ingredients at clinical doses alone is enough to have a massive impact on performance, but this is just the beginning of what Fury Version 2 has to offer.

The fun and tremendous boost in performance really starts with the inclusion of several trademark ingredients like VasoDrive-AP®, Citrapeak®, Senactiv™, and Zum-XR® Caffeine, as well as other well-known ingredients like Cocoabuterol. These ingredients are used at or above serving sizes suggested by clinical research to dramatically boost athletic performance, hydration, mental clarity, strength and power, muscle pumps, and energy. The end result is an absolute haymaker performance punch and a pre-workout formula that has set a new standard in the category of fully-loaded pre-workouts.

Now, I know you're all eagerly awaiting to see the entire formula, and how Core could have possibly made an already colossal formula even better. So, let's break down this worthy "successor" formula and see if this one truly does constitute the latest evolution of the pre-workout formula.

Core Fury V2

L-Citrulline - 6,000mg
L-Citrulline is a non-essential amino acid that is widely used as a performance-enhancing ingredient by athletes and bodybuilders of all levels.

As a result, L-Citrulline has been shown to have a number of benefits for athletic performance including delivering more oxygen and nutrients to the muscles during exercise, which can improve performance and reduce fatigue.

A clinical dose of L-Citrulline is typically considered to be in the range of 6,000-8,000mg per serving. This amount has been shown in various clinical studies to have significant improvements in athletic performance, particularly in terms of strength, power, and endurance. Here's how:

• Increases Nitric Oxide Production: L-Citrulline increases the production of nitric oxide, which helps to relax blood vessels and increase blood flow to the muscles, improving oxygen and nutrient delivery.

• Reduces Fatigue: L-Citrulline can reduce the feeling of fatigue during exercise by increasing the removal of ammonia, a byproduct of energy metabolism that can contribute to muscle fatigue.

• Enhances Energy Production: L-Citrulline can enhance energy production by increasing the production of adenosine triphosphate (ATP), the primary source of energy for muscle contractions.

• Boosts Muscle Protein Synthesis: L-Citrulline can stimulate muscle protein synthesis, which is the process by which the body builds new muscle tissue.

• Improves Recovery: L-Citrulline can improve post-exercise recovery by reducing muscle soreness and inflammation.

• Enhances Endurance: L-Citrulline can improve endurance by increasing the rate of oxidative ATP production, which is the primary energy source used during endurance exercise.

VasoDrive-AP® - 254mg

VasoDrive-AP® is a patented ingredient that contains two bioactive peptides, which are naturally derived from milk protein. The peptides in VasoDrive-AP® have been shown in clinical studies to promote vasodilation, or the widening of blood vessels, which can improve blood flow to the muscles during exercise.

At a dose of 254mg, VasoDrive-AP® has been shown to have a significant effect on increasing blood flow and improving athletic performance. Here's how:

 VasoDrive-AP® promotes the production of nitric oxide in the body, which helps to increase blood flow and improve oxygen delivery to the muscles during exercise.

 It inhibits the production of angiotensin II, a hormone that causes blood vessels to constrict, thereby allowing for better blood flow and increased oxygen delivery to the muscles.

 VasoDrive-AP® helps to reduce inflammation, which can lead to improved recovery time and reduced muscle soreness after exercise.

 It has been shown to improve endothelial function, which is important for overall cardiovascular health and athletic performance.

 VasoDrive-AP® has been clinically demonstrated to improve endurance performance and increase time to exhaustion during exercise, allowing athletes to train harder and longer.

Citrapeak® (glucosyl hesperidin) - 200mg

Citrapeak® is a patented form of glucosyl hesperidin, a type of bioflavonoid derived from citrus fruits. Bioflavonoids are plant-based compounds known for their antioxidant properties and potential health benefits. Glucosyl hesperidin is a modified form of hesperidin, which is found naturally in citrus fruits such as oranges, lemons, and grapefruits. However, glucosyl hesperidin is more easily absorbed by the body than hesperidin alone.

It has been clinically studied showing some true potential for boosting athletic performance and recovery. Here's how:

• Increased Nitric Oxide (NO) Production: Citrapeak® has been shown to increase nitric oxide production, which can improve blood flow and oxygen delivery to working muscles.

Beta-Alanine - 3,200mg

Beta-alanine is a naturally occurring amino acid that plays a crucial role in the production of carnosine, a dipeptide that helps buffer acidity in the muscles during high-intensity exercise. Supplementing with beta-alanine has been clinically tested and shown to increase muscle carnosine levels, which can  improve exercise performance.

It has become a staple pre-workout formulas because of its innate ability to increase performance during high-intensity exercise. It is typically dosed between 2-5 grams per day and can cause a harmless, yet uncomfortable, tingling sensation in the skin known as paresthesia. These are also known in the fitness community as the "beta-tingles". 3.2 grams is a clinical and scientifically substantiated dosage, and will provide substantial benefits in increasing athletic performance. Here's how:

• Increases muscle carnosine levels: Beta-alanine is the limiting factor in the synthesis of carnosine, so supplementing with beta-alanine can increase the concentration of carnosine in muscles. Carnosine helps buffer the accumulation of lactic acid during exercise, delaying the onset of fatigue and allowing for longer and more intense workouts.

• Enhances muscular endurance: Higher levels of carnosine in muscles can lead to an increased capacity for high-intensity exercise, especially during short-duration, high-intensity efforts.

• Improves anaerobic performance: Beta-alanine supplementation has been shown to improve performance in anaerobic exercises that require short bursts of energy, such as sprints and weightlifting.

• Increases time to exhaustion: Beta-alanine has been shown to increase the time to exhaustion during high-intensity exercise, meaning that athletes can perform at higher intensities for longer periods of time before becoming fatigued.

Senactiv™ - 50mg

Senactiv® is a 100% all natural plant-based compound that is a blend of Panax notoginseng and Rosa roxburghii. These bioactive compounds enhance mitochondrial function and promote the production of cellular energy in the body. By doing so, Senactiv®i delivers some astounding benefits for improving athletic performance! Here's how:

• Increase ATP production: Senactiv® contains a unique compound called Notoginsenoside R1 that has been shown to activate an enzyme called AMPK (AMP-activated protein kinase). AMPK is known as the "metabolic master switch" as it plays a crucial role in regulating energy metabolism.

When activated, AMPK stimulates an increase in the production of ATP (adenosine triphosphate), the primary energy currency of cells. This increase in ATP production can help to enhance athletic performance by providing more energy for muscle contractions, reducing fatigue, and improving endurance.

• Boost VO2 max: Senactiv® increases endurance by improving the 80% VO2 max time to exhaustion by 20%. It also helps to improve cellular renewal and regeneration. It does this by speeding up the time it takes for the body to eliminate old, senescent cells so that they can be replaced by new, healthy cells. Benefiting the performance of the muscle cells.

• Enhanced recovery: Senactiv® helps to reduce oxidative stress and inflammation in the body, which can improve recovery time after intense exercise.

• Improved muscle strength and power: By promoting energy production in muscle cells, Senactiv® may help to increase muscle strength and power output during exercise.

• Increased mental focus: Senactiv® also provides cognitive benefits, such as increased mental focus and improved mood, which can help athletes stay motivated and focused during training and competition.


Taurine - 2,000mg

Taurine is a powerful and very abundant amino acid. In fact, it is the second most abundant amino acid in the body's muscle behind glutamine. It is highly present in the brain and spinal cord, leukocytes, heart and muscle cells, the retina, and indeed almost every tissue throughout the body. Taurine exists in very high concentration in the brain and plays a neuromodulatory role in this area.

The body makes Taurine by breaking down the amino acid cysteine. It is shown to enhance muscle contraction to boost power and rid the muscle of lactic acid, improving recovery. Much like Betaine Anhydrous, it's also an osmolyte that will increase cell volumization and muscle cell uptake, and boost cellular hydration. This gives Taurine the innate ability to enhance athletic performance in multiple ways! Here's how:

• Reduces muscle damage and fatigue: Taurine has been shown to reduce muscle damage and fatigue caused by exercise, which can improve overall exercise performance.

• Better peak muscle contractions: Taurine plays a crucial role in muscle contractions. It acts as an osmolyte, which means it helps to regulate the balance of water and electrolytes in and out of cells. This can help to prevent muscle cramps and reduce muscle fatigue during exercise.

Taurine also helps to regulate the levels of calcium in muscle cells. Calcium is an important mineral for muscle contractions, and taurine helps to ensure that the right amount of calcium is available for muscle cells to function properly.

• Increase power output: Taurine can enhance muscle contractility by increasing the sensitivity of muscle fibers to calcium, which is an essential mineral for muscle function. By increasing the sensitivity of muscle fibers to calcium, taurine can enhance the force and power generated by muscle contractions. This can result in increased strength and power during exercise, particularly during high-intensity activities like weightlifting and sprinting.

• Increases endurance: Taurine can help increase endurance by reducing the amount of oxidative stress that occurs during exercise, which can help athletes perform for longer periods of time.

• Boosts mental focus: Taurine may also help improve mental focus during exercise, allowing athletes to maintain their concentration and perform at their best.
