Cellucor is a well-established American sports-nutrition company founded in 2002, known for producing a wide range of dietary supplements tailored to athletes, bodybuilders, and fitness enthusiasts. Their product portfolio includes high-performance pre-workouts (most famously the C4 line), proteins, recovery formulas, fat-burners and other performance-driven nutritional products.

Operating under the umbrella of Nutrabolt (legally Woodbolt Distribution, LLC), Cellucor is part of a larger active-health business that also owns other key brands like C4 Energy and XTEND.

The mission of Nutrabolt—and by extension Cellucor—is to “innovate, inspire, and make products that maximize human potential accessible to all.”

Cellucor has experienced significant growth since its early days. In 2009, the brand began being stocked in major retailers like GNC. Their signature C4 pre-workout product was launched in 2011, first under the “Chrome Series” packaging, and has since evolved through multiple generations (such as the “G4 Series”) to include a variety of tailored formulations—for example, products focused on weight gain, fat loss, cognitive support, or high-stim energy.

In addition to powder-based supplements, Cellucor (through Nutrabolt) expanded into ready-to-drink nutrition: in 2018, they launched C4 Energy, a carbonated performance drink that now comes in a number of variants including “Performance Energy,” “Smart Energy,” and “Ultimate” formulations.
