Fully Loaded Formula
In Single-Scoop Dose
The Ultimate Pre-Workout
The word "ultimate" gets tossed around a lot these days. People love to claim they've created the ultimate training method, diet, or supplement, often without substantial evidence to support such bold statements. So what makes C4 Ultimate worthy of its name? How do we back up the word "Ultimate" to ensure this is the strongest, most effective, most powerful pre-workout on the market?*
Take a look at the key factors
that make C4 Ultimate.
Powerful Key Ingredients
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.*
NO3-T creatine nitrate (1.5g)
A university-studied form of creatine formed when creatine is bonded with nitrate anions. On the individual level, Creatine and nitrate are powerhouse elements, but when fused together, they create an unstoppable bond.
Shown to significantly increase arginine and nitric oxide levels for up to 3 hours.*
Precursor to nitric oxide that promotes nitric oxide production in the body.*
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.*
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.*
C4 Ultimate 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 combines everything we've learned over years of study and real-world product development to deliver energy you can feel, powerful pumps, muscular endurance, extreme focus, and peak performance. Consider C4 Ultimate a masterpiece from pre-workout craftsmen.*
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. We're proud to say that C4 Ultimate contains six patented ingredients from leading ingredient companies of the highest caliber:
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 delivers an ultimate experience on every level: the ultimate in energy, pumps, endurance, performance, and focus. This is not a pre-workout for the weak for weekend warrior. C4 Ultimate has been engineered for athletes, lifers, and lifters who aren’t afraid to work, sweat, and hustle for their next best.*
The C4 Ultimate formula delivers the explosive energy and performance you love from C4, plus a powerful combination of nootropics, mood enhancers, pump amplifiers, and endurance support to push you to your ultimate limit.*
The Cellucor Difference
Every tub of C4 Ultimate 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.
