Your calendar says one thing. Your blood tells another story. This calculator uses the Levine PhenoAge algorithm — a peer-reviewed formula from 9 standard blood biomarkers — to estimate how fast your cells are actually aging. The gap between your biological and chronological age reveals how well your body is holding up, and more importantly, what you can do about it.
You will need these from recent bloodwork:
Albumin, Creatinine, Glucose, Alkaline Phosphatase (ALP) from your CMP · WBC, Lymphocyte %, MCV, RDW from your CBC · hs-CRP from a CRP panel
Important: This calculator uses the Levine PhenoAge algorithm (Levine et al., 2018), a peer-reviewed tool based on NHANES population data. Results are statistical estimates, not a clinical diagnosis. Biomarkers can be influenced by acute illness, recent exercise, medications (including TRT), fasting status, and lab variability. A single set of labs provides a snapshot — trends over time are more meaningful. Always discuss results with your healthcare provider.
