Your breath holds the blueprint to your metabolism and longevity.
PNOĒ testing decodes it — revealing how efficiently your body burns fuel, adapts to stress, and supports long-term vitality. At Peak by MD: Longevity & Aesthetics Club, this test forms the cornerstone of our precision approach to weight loss, performance, and aging well.
A personalized starting point for your health, aesthetics, and longevity.
Answer a few short questions so we can recommend the most effective next step, without guesswork. This assessment takes approximately two minutes and is designed by the Peak by MD clinical team. All responses are private and confidential.
PNOĒ testing gives you the data behind your metabolism, performance, and longevity—three systems that all depend on how efficiently your body delivers and uses oxygen. When oxygen flow through the lungs, heart, and cells is optimized, everything improves: metabolism accelerates, endurance increases, and aging slows.
Most diets fail because of metabolic slowdown—your body adapts and burns fewer calories, even while you’re trying harder. PNOĒ identifies this slowdown early, allowing precise adjustments to nutrition, exercise, and recovery that reignite progress.
In short, oxygen flow is the ultimate marker of vitality.
By mapping how effectively your body uses O₂ at rest and under stress, PNOĒ uncovers the hidden barriers to fat loss, energy, and longevity—turning every breath into actionable insight.
You’ll relax in a reclined position while breathing through a mask for 10 minutes. The PNOĒ system measures your oxygen consumption and carbon dioxide output to calculate your energy needs and metabolic efficiency.

A graded treadmill or cycle test lasts 10–15 minutes. You’ll wear the same PNOĒ mask as intensity gradually increases. The data reveals how your oxygen consumption, CO₂ output, and heart rate change under stress.
