“Science in the bloodstream. Story in the soul. Spartan spirit in the gym.” Meet Dr. Marcus Ranney, a high-performance longevity physician, tech entrepreneur, and modern-day explorer who is redefining healthspan from the Himalayas to the boardroom. Trained in elite science and seasoned by the extremes (think ultra-marathons in deserts and Arctic ski expeditions), he brings cutting-edge biohacking to athletes, astronauts, and now, to ambitious executives and wellness-conscious individuals across India.

Marcus is the mind behind Human Edge, a next-gen longevity platform blending clinical biomarker insights with digital intelligence. Whether it’s building a protocol for a CEO, launching a science-backed intervention, or busting pseudoscience with Attia-level rigour, Marcus is all in.
