What is Cellucor C4 Extreme?

Since the beginning of time, energy has been the world's most sought after commodity.

In ancient mythology, Prometheus stole fire and gave man his first flame.

In today's world, wars are fought over energy.

The supplement universe has a war of its own; countless brands employ relentless advertising and promotional campaigns to announce that their product delivers the most energy. No product has ever fully delivered on this seemingly simple promise; customer's routinely admit they stray from brand to brand, product to product, to try and find a better solution—and a product that will remain effective after the first few doses.

The Search is over; Cellucor has the answer. C4 Extreme is powdered energy. Harnessing our NO3 technology and effective ingredients including creatine nitrate, Beta Alanine, and Arginine AKG, C4 Extreme is our advanced pre-workout supplement, possessing the power to ignite your mind, muscles, and workout regiment, workout after workout after workout.

What is NO3? NO3 is Nitrate, an advanced compound that promotes unbelievable muscle pumps and amplifies the effectiveness of C4 Extreme.* Cellucor is utilizing a new compound where NO3 has been fused to create Creatine Nitrate. Increased water solubility promotes better absorption and reduce the chance of the traditional side effects of Creatine supplementation.

You will have more energy. You will have help getting that extra rep, completing that last set - promoting strength, endurance, and physique personal bests.

Cellucor C4 Extreme has Energy/Focus Blend


N-Acetyl-L-tyrosine is a more rapidly absorbed and bio-available form of L-Tyrosine that is less prone to urinary excretion.* L-Tyrosine is an amino acid precursor to the adrenals.* These hormones support and contribute to higher energy levels, awareness, and mental alertness.


Mucuna Pruriens is widely known as the velvet bean. Mucuna Pruriens a naturally occurring amino acid derivative that converts in the brain. This is one of the most powerful compounds for body recomposition.


Methylcobalamin is a potent form of Vitamin B12, an essential B-vitamin. Vitamin B12 greatly supports cellular metabolism and energy productions and aids in the production of fatty acids - broken down fats that are then easily burned.* Vitamin B12 also promotes healthy nervous system function and blood formation.


Caffeine is a powerful stimulant.* Caffeine stimulates the central nervous system, warding off fatigue and promotes increased alertness and energy levels.


Niacinamide is a water-soluble B-complex vitamin. Niacin, or nicotinic acid, also known as Vitamin B-3, improves joint mobility, muscle strength, and nervous system function. Niacinamide decreases muscular fatigue and increases maximal muscle working capacity.


Folic acid is a water-soluble B-vitamin that promotes positive mood and higher energy levels.* Folic acid also supports healthy cell formation and repair.

Cellucor C4 Extreme has an Amazing Taste and Mixability

The science behind C4 Extreme doesn't end with a superior formula - C4 Extreme is a great tasting and ultra - mixable product. C4 is immediately available in refreshing Tropical Fruit Punch and Orange flavors and has been formulated to enhance solubility making it one of the easiest to mix powdered supplements to date.

C4 Extreme has an Unparalleled label Transparency

Cellucor has set another industry first by drastically improving label transparency. Beginning with the "Chrome Series" line, Cellucor has clearly labeled all key ingredient dosages - no more confusing proprietary blends, no more wondering what you're actually taking. It is our firm belief that greater information accessibility will allow us to deliver greater results

  • 1.3/10  Bad batch

    By Old_dude on Thursday, October 4, 2018 12:51 PM

    Effectiveness: 1/10

    (-)  Gave Me An Upset Stomach,Mixes Poorly,Not Effective,Too much food colouring and stained teeth / lips

    How did you use it?:Before Exercise

    "I clearly got a container from a bad batch. Had to return and also contacted cellucor directly. The blue colouring stained my teeth and lips and I also had a very upset stomach for several days. There was also no noticeable energy boost from using this batch. And not to be too descriptive but the blue colouring / die travelled ALL the way through my digestive system.
    I have used the product for over 5 years and never had an issue like this, so I'm hoping it's a one off, but I am definitely turned off using it for now."

    Effectiveness: 10/10

    (+) Boosts Energy,Easy To Take,Mixes Well,Tastes Great

    How did you use it?:Before Exercise

    "I'm fairly new to preworkouts, but C4 is a good introductory one, I can feel the boost in endurance but I don't feel weird or jittery. I definitely felt my endurance on the airdyne bike increase and I was able to go longer without as many breaks. I take it only on evening workouts after I've worked long shifts, it really gets me in the mindset to do a workout even if I am tired from a full of work."
