BOLDLY UNCONVENTIONAL

WHEN LIMITS FADE, POSSIBILITIES BEGIN

We've been revolutionizing endurance nutrition since 2002. From our very first product, Optygen, we’ve set the standard with groundbreaking innovation, clinically-proven ingredients, and state-of-the-art technology.

Every decision we make is guided by one simple question: will it help athletes defy the limits of what’s possible?

THE ULTIMATE TESTING GROUND

Our office is our lab is our playground: Salt Lake City’s Wasatch mountains at 4,400 feet. With iconic climbs, mountain lakes, and endless trails, it's the ultimate endurance playground. Here we collaborate with our team of elite athletes and leading doctors to develop groundbreaking endurance nutrition that pushes the boundaries of performance.

WE LIVE FOR THIS

ACHIEVING THE IMPOSSIBLE, TOGETHER

We've spent countless hours driving to races and have stayed in more grungy hotels than we care to remember.  Our passion for training and racing influences everything we do. It’s not just what we do — it’s who we are.
