Method
From raw data to
longevity insight
in four steps.
Every step maps to something measurable in the peer-reviewed literature. No wellness scores. No proprietary vibes. Just a pipeline from inputs to insight.
01 · Data ingestion
Import
Connect Apple Health. Upload Cronometer CSVs. Paste blood panels. One timeline.
▲ STEP 01
02 · Biomarker tracking
Measure
40+ markers across 13 categories, plotted against optimal ranges from the literature.
▲ STEP 02
03 · Bio-age model
Compute
PhenoAge (Levine 2018) from 9 serum markers. Your real biological age, not a wellness score.
▲ STEP 03
04 · Personalized insight
Optimize
Statistical analysis of your own data is used to derive insight for optimizing biomarkers.
▲ STEP 04
Platform
Everything you need
to optimize longevity.
Built from a decade of self-experimentation. Discover your personalized recipe for optimal health.
Blood biomarkers
40+ markers across 13 categories, plotted against optimal ranges. Covers biomarkers related to CVD risk, metabolic and hormonal health, inflammation, liver, kidney, immune, red blood cell-related measures, neurogenesis and neurodegeneration.
Health vitals
Apple Health and Whoop sync: HRV, heart rate, sleep stages, steps, VO₂ max, body composition. Your full telemetry in one timeline.
Nutrition
Cronometer integration for macros, micros, and calories, correlated with every biomarker shift over time.
New
AI insights
Chat with an AI trained on Dr. Lustgarten's decade of research and 500+ YouTube videos. Cited, data-driven, not internet takes.
Supplements
Log your stack, doses, and timing. See which compounds actually correlate with biomarker improvements, and which quietly don't.
Yours
Your data, only.
Encrypted at rest, never sold, never trained on. Export every marker, every meal, every reading as CSV the moment you ask.

About the creator
Michael
Lustgarten, PhD
"My goal is to live longer than anyone that's ever lived."
PhD in Physiology from the University of Texas Health Science Center at San Antonio (2009), and 15 years as a scientist on Tufts University's Nutrition, Exercise Physiology & Sarcopenia team, dedicated to understanding aging at the molecular level.
After 10+ years of rigorous n=1 self-experimentation, he built this platform to bring the same data-driven approach to anyone pursuing optimal health. Those years included tracking biomarkers of every major organ system, correlating diet and supplementation with outcomes, and documenting it all publicly.
