Biological age testing

Biological age testing estimates how fast your body is aging compared to your calendar age using biomarkers like bloodwork, epigenetics, and fitness metrics. Learn what these tests can (and can’t) tell you and how to use results to guide training, nutrition, sleep, and hormone optimization for better health and performance.

Bryan Johnson’s commercial “Blueprint Stack” promises a simplified route into a longevity-focused routine. This blueprint stack review breaks down what’s actually in the stack as described, what the research says about the major components for men, and how to use a “stack” approach without drifting into expensive guesswork. “If a ‘stack’ helps you consistently hit ...

For longevity-focused men who train, repeating key labs—especially HbA1c (a ~3‑month average of blood sugar) and ApoB (the number of atherogenic particles that can enter artery walls)—can reveal early metabolic drift and cardiovascular risk before performance drops or disease shows up. Pair those with iron, inflammation, and hormone/recovery markers to build a “healthspan dashboard” that ...

Men’s longevity is shifting from speculative biohacking to evidence-based healthspan medicine that targets upstream biology—especially chronic low-grade inflammation (“inflammaging”), metabolic flexibility, and cellular repair—before disease and hormonal decline become entrenched. Here are the clinically grounded trends and tools (from precision testing to targeted interventions) that can help a man’s 70s function more like his 50s. ...

Wearables, lab panels, and health apps are turning midlife checkups into data streams. Here is how smarter report optimization in men can turn those numbers into better energy, libido, and long-term health. “Most men now have more health data than their doctors had 20 years ago. The real win is not more testing, but turning ...

To make the most of comprehensive biomarker testing, interpret the 100+ lab results as a multi‑marker pattern (for example, LDL cholesterol, triglycerides, C‑reactive protein, and blood pressure together) to better predict your 10‑year cardiometabolic risk than any single “high” or “low” number. Here’s how to translate that pattern into concrete choices about food, movement, sleep, ...
