In 2011, the Original C4® Extreme came to define the pre-workout category. Building on that heritage and legacy, the new C4® Extreme has been reengineered and reimagined from the ground up to help support explosive energy, extreme performance, and mental alertness.*

As part of Project Clear Evolution, C4® Extreme is founded on three core principles. Clean: no artificial dyes and no artificial flavors, Clear: fully transparent labels and no proprietary blends, and Evolved: innovative ingredients and enhanced formulas.
