Every scoop of C4 Sport combines two formulations to support performance and energy into one, including 135mg caffeine and ZERO sugar so every base of your workout is covered for unrivaled focus and training. It’s your secret weapon to maximizing performance, staying energized, maintaining focus, and tackling any goal in your way. 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. Every tub of C4 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:

Flavor: 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.

Ingredients: 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.)

Product development: 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.

Commitment to customers: We’re committed to your results. At the end of the day, C4 is your product. If you don’t like it for any reason, we’ll gladly refund or replace it. We’re here for you.
