A Cellular Diagnostic

Your biological
age is not your
birthday.

Two people, same age — one ageing twice as fast. A short questionnaire, scored against published longevity research, will tell you which one you are.

I
Answer honestly
Sleep, exercise, stress, diet — the key lifestyle markers scored against longevity research.
II
We score it
Your answers are weighted against published longevity research to calculate a cellular age estimate.
III
You see the gap
Your biological age vs. your chronological age — and which factors are driving the difference.

Chronological age is a calendar.
Biological age is what counts.

Two people born in the same year can have radically different cellular ages — a gap driven by sleep, stress, movement, diet and metabolic health. Published research has documented this divergence consistently across multiple studies covering muscle, liver, heart and brain tissue.

This diagnostic uses the markers most strongly correlated with biological age in peer-reviewed literature. It is not a clinical test — it is a scored estimate, built to be directionally accurate and genuinely useful.

Sleep duration & quality
Exercise & resistance training
Chronic stress level
Diet quality & plant diversity
Body composition
Alcohol & smoking exposure
Social connection
Mood & mental wellbeing
Hydration & time outdoors
Existing conditions
Family longevity
Daily energy patterns
Is this a real test?
It's a scored questionnaire based on published longevity research, not a clinical blood test or DNA analysis. It gives a directional estimate — not a lab result. Think of it as a structured mirror, not a diagnosis.
Do I need to give my email?
No. You can complete the diagnostic and see your result without entering any personal information. Email is offered at the end only if you want your result saved to your inbox.
How accurate is it?
More accurate than most people expect, less accurate than a blood panel. The markers used are the strongest lifestyle predictors documented in peer-reviewed literature. The result is directionally reliable — but it's a starting point, not a verdict.
Will I be sold something?
Your result includes a product recommendation — honestly, yes. But the diagnostic is genuine and the result is scored on your answers. The recommendation follows from the result, not the other way around.

Takes 60 seconds. No email required. Instant result.

This diagnostic is a scored lifestyle questionnaire for informational purposes only. It is not a medical test, clinical assessment, or substitute for professional health advice. Results are estimates based on self-reported data weighted against published research. Consult a qualified healthcare professional before making any health decisions.
