What is intermittent hypoxia exposure (HEPOX)?
Induces controlled periods of hypoxia (reduced oxygen) to stimulate oxygen efficiency adaptations and promote red blood cell production.
Studies show results in 10-20% increase in strength and 3-5% improvement in 1000meter times.
HEPOX is designed for use during rest, at home, or while traveling.

About the founder - david greif
HEPOX was born from necessity. As a mechanical engineering student and aspiring pro cyclist, I hit a performance plateau that effort alone couldn’t overcome. To compete with the best, I needed the same physiological edge that many professional athletes seek— altitude adaptation. I had heard from other professinoals about altitude effects on red blood cell production, but a $6,000 setup wasn’t an option (especially not one that takes over your bed). So I set out to build a better solution. I invented HEPOX: a compact and affordable device that safely simulates high-altitude oxygen levels to trigger red blood cell production and oxygen-efficiency adaptations. The results were transformative, helping me earn a professional racing contract. Now that I am retired from professional racing, I’m bringing HEPOX to athletes everywhere—making elite-level training accessible and portable.
Our
brand vision
HEPOX is now available. This early version lays the foundation for future models, which will feature biometric feedback and acclimation tracking integrated with a companion app. As a thank-you for supporting our development, purchasing any HEPOX now will grant you 50% off a future upgraded version.
