Powerful Key Ingredients
Testosterone & Performance Blend
A daily serving in healthy adult men supports normal testosterone levels, strength, muscle size, sexual function, and endurance.*
Supports healthy testosterone levels while minimizing the unwanted conversion of testosterone to DHT.*
Shown to support an increase in lean muscle & strength, promote increased power output and training volume, and support higher levels of mitochondrial ATP – the energy currency of the body.*
Caffeine is a well-studied stimulant that has numerous energy, performance, and even fat-loss benefits.*
Tetramethyluric acid, or theacrine, is an alkaloid structurally similar to caffeine. Preliminary human study results suggest that the body doesn't adapt to TeaCrine as quickly as it does to caffeine, therefore prolonging tolerance.*
This plant extract may act similarly to yohimbine, and its effects are amplified when paired with caffeine.*
Citrulline Malate (6g)
A precursor to arginine and nitric oxide production, 6 grams of citrulline may support an increase in nitric oxide levels.* It supports the ultimate pump, especially when paired with arginine.* Note that 6 grams is the entire scoop size of some pre-workouts. In C4 Ultimate, it's just the pump foundation.*
Citrulline Nitrate (1g)
The latest Citrulline innovation technology - to help you achieve the ultimate pump.*
CarnoSyn® Beta-Alanine (3.2g)
A full, clinical dose of this patented form of beta-alanine supports muscular endurance.* Beta-alanine can sometimes produce a harmless skin-tingling sensation.
BetaPower® Betaine Anhydrous (1.5g)
Helps maintain cellular electrolyte balance and promotes hydration.*
Supports an increased mind-muscle connection in the gym.*
Supports positive mood and cognitive function.
A nootropic that may support memory, learning, and concentration.*
Helps support mental performance when paired with caffeine and B vitamins.*
A Legacy of Excellence
We've been pioneering, building, and perfecting pre-workouts longer than most brands have been in sports nutrition. For nearly a decade, the C4 family has led the pre-workout category with explosive energy and performance, the best flavors, clinically studied ingredients, and cutting-edge formulas.*
We're obsessed with research, improvement, and results. We're innovators and leaders, and we're not new to our work. We have a legacy of building the best, most effective pre-workouts available.
We can comfortably say, without a doubt, that the C4 Ultimate line is the strongest series of pre-workouts we've ever created.
The C4 Ultimate line is the culmination of a decade of hands-on work in the pre-workout space. We're not talking about building a product in a matter of months. C4 Ultimate Power combines everything we've learned over years of study and real-world product development to deliver testosterone support on top of energy you can feel, powerful pumps, muscular endurance, extreme focus, and peak performance.* Consider C4 Ultimate Power a masterpiece from pre-workout craftsmen.
Clinically Studied,Patented Ingredients
No matter how big the scoop size or how revolutionary it claims to be, a great pre-workout starts with best-in-class ingredients used in effective doses. Since ingredients are not created equal, patented ingredients are important for multiple reasons, particularly because they're backed by quality manufacturers who rigorously test and research their products to ensure efficacy and safety.
Patented ingredients are the best in their categories, or they're so novel that they're complete category-creators. C4 Ultimate® Power’s legendary P6® Testosterone and Performance Blend supports healthy test levels along with increased strength, muscular size, sexual function, and endurance.*
The Ultimate Formula
Creating the perfect pre-workout for people who demand nothing less than the best from themselves and their supplements has been no easy task. It's taken us years of work, the best ingredients from around the globe, and a consistent commitment to innovation, formulation, and product development.
We're proud to say that the formula powering each serving of C4 Ultimate Power delivers an ultimate experience on every level: the ultimate in testosterone support, energy, pumps, endurance, performance, and focus.* This is not a pre-workout for the weak or weekend warrior. C4 Ultimate Power has been engineered for athletes, lifers, and lifters who aren’t afraid to work, sweat, and hustle for their next best.*
The C4 Ultimate Power formula delivers the explosive energy and performance you love from C4, plus a legendary testosterone technology blend, nootropics, mood enhancers, pump amplifiers, and endurance support to push you to your ultimate limit.*
The Cellucor Difference
Every tub of C4 Ultimate Power is the result of rigorous testing and research to ensure you get the highest-quality product possible, without compromise.
Our commitment to the following areas makes Cellucor stand above the pack:
We put every flavor of C4 through 100s of flavor tests. Seriously. And we don't settle. If a flavor doesn't measure up, we move on. We're dedicated to making the industry's best-tasting products, and nothing less will do.
We utilize an industry-leading evaluation method when working with ingredient suppliers, and we conduct additional stability testing on our raw ingredients to make sure our formulas have great physical stability. We also visit our key ingredient suppliers directly so we know exactly what we're putting in products, and we're very selective about working with only the best partners. (The same is true with our packaging.)
Our in-house product development team has years of research and expertise, and a true passion for sports nutrition. We don't rely on a single person's opinion to build product. We have a team of world-class formulators who evaluate, debate, and discuss the latest research before we even put a formula down on paper. Add our incredible relationships with the world's best ingredient manufacturers, internal testing, athlete feedback, and years of leading the industry, and you get a development process that's second to none.
