Research does not show that the branded “Blueprint Stack” supplement bundle itself improves vascular health outcomes in men; any likely benefit comes from the Mediterranean-style foods in the routine and the cardiometabolic improvements they support. This men’s health-focused Blueprint protocol review explains what’s in the stack based on public descriptions of Bryan Johnson’s Blueprint protocol, ...

For longevity-focused men who train, repeating key labs, especially HbA1c (a three 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 and recovery markers to ...

A “normal” BMI is 18.5 to 24.9 kg/m². It is a population screening tool and does not directly measure body fat, muscle mass, or visceral fat, so use it as a starting point. Pair BMI with waist circumference, body composition, and a few core metabolic labs to decide what to change and what to track. ...

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, ...

DNA methylation tests estimate biological age and population-level risk patterns, but they cannot diagnose disease or reliably tell you which supplements you need. They measure methyl groups attached to cytosine at thousands of CpG sites and use algorithms (epigenetic clocks) to generate scores. Here’s how to read a Gary Brecka style methylation report without overpaying ...
