Over two years in the making, spanning multiple formula tweaks and hundreds of flavor tests, C4 Extreme has been re-engineered and re-imagined from the ground up to help support explosive energy, extreme performance, powerful pumps, and mental alertness.* This is the product that defined a category, now evolved and updated.
We ran C4 Extreme through several hundred rounds of flavor sampling to make sure it exceeds every expectation, and we didn't settle for anything less than the best.
If a flavor didn't measure up, we moved on. We're proud to say that C4® Extreme's flavor array wins in every way — including our new, naturally sweetened flavors.
