We've been pioneering, building, and perfecting pre-workouts longer than some brands have been in sports nutrition. For nearly a decade, the C4® family has led the 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. We have a legacy of building the best pre-workouts on the market, because that's precisely what we want to take. All our obsession comes together in C4® Ultimate Project Clear Evolution. Ultimate delivers energy you can feel, powerful pumps, muscular endurance, extreme focus, and peak performance.*
Since its launch in 2016, C4® Ultimate has defined what it means to be the industry's best pre-workout, delivering unrivalled energy, focus, pumps, and performance. To lead the pack and remain the best, the best don't rest—they evolve. This is the evolution of C4® Ultimate.*
The new generation of Ultimate delivers enhanced training benefits on every level, includes new performance ingredients for even stronger pump power, and joins the ranks of Project Clear Evolution.*
Every product built on the Project Clear Evolution platform is founded on three core pillars:
As our Clean, Clear, and Evolved pre-workout powerhouse, C4® Ultimate is free from artificial flavors and dyes, made with a fully disclosed formula, and upgraded with cutting-edge performance ingredients like NitraMax (NO3-C)™ Citrulline Nitrate and a double dose of pump-boosting nitrates.*
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.*
