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.
