As America's #1 pre-workout brand*, we've been pushing the boundaries of performance energy since 2011. Leading. Innovating. Defining what it means to be the best with incredible flavors, cutting-edge formulas, and uncompromising performance. Now, it's time to shatter those boundaries. To leap forward. To evolve.
Introducing Project Clear Evolution: our mission to set a higher standard. To elevate the entire C4® family—and beyond—by pioneering the next generation of premium performance supplements that exceed your expectations.**
Project Clear Evolution is founded on three pillars:
These core principles are the backbone of Project Clear Evolution. We're swapping artificial colors and flavors in favor of more naturally-derived options, peeling back prop blends to showcase all the performance ingredients that make our products tick, and boosting our formulas with enhanced inputs for extreme performance. This is the future of sports nutrition, and it starts with the all-new C4® Extreme.
Created by bonding citrulline with patented nitrates, NitraMax (NO3-C) is an advanced compound that delivers dual-pathway nitric oxide (NO) support. Unlike citrulline or citrulline malate, which work through a single mechanism, NitraMax™ supports two mechanisms of NO creation, the arginine pathway (eNOS) and the nitrate-nitrite conversion system, to help promote the ultimate pump.
Over two years in the making, spanning multiple formula tweaks and hundreds of flavor tests, C4® Extreme has been reengineered and reimagined 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.**
Building on the legendary C4® performance formula, C4® Extreme is formulated with the following patented and clinically studied ingredients in to fuel your most extreme training sessions.
Directions For C4 Extreme: Take one serving (approx. 1 level scoop) of C4® Extreme mixed with 6 fl. oz. of water, 20-30 minutes before training.
