Biological Age Quiz

What's Your Body's Real Age?

Two people born the same year can have biological ages 10+ years apart. Sleep quality, recovery speed, mental clarity, and body composition tell the real story. Answer 7 questions below. Takes 60 seconds.

Your Lifestyle Assessment

Your chronological age

How would you rate your daily energy?

Exhausted by noon

Afternoon crash

Steady most days

High all day

How well do you sleep?

Poor — wake up tired

OK — some nights bad

Good — 7 hrs most nights

Great — deep, restful

How quickly do you recover from exercise or exertion?

Days of soreness

1-2 day recovery

Next day fine

Bounce back fast

How's your mental clarity and focus?

Foggy — can't focus

Scattered some days

Clear most days

Sharp — laser focus

How satisfied are you with your body composition?

Gaining fat, losing muscle

Harder to stay lean

Maintaining OK

Lean and strong

Libido and drive?

Gone — no interest

Lower than before

Normal for my age

High — no issues

How do you handle stress?

Overwhelmed often

Manage but feel it

Handle it well

Thrive under pressure

Your biological age might surprise someone else enough to check theirs.

How this estimate is calculated: This quiz uses a weighted lifestyle assessment based on published research correlating sleep quality, recovery speed, body composition, mental clarity, stress response, and libido with biological aging markers (DNA methylation, telomere length, IGF-1 levels). It is an educational estimate, not a clinical biomarker test. Actual biological age can only be measured through lab testing (epigenetic clocks like Horvath's clock, PhenoAge, or GrimAge). Strut Sermorelin, NAD+, Mito-Essense, and Telo X Nano are telehealth and supplement programs — individual results vary. Consult a physician before starting any new regimen.

Common Questions About Biological Age

What is biological age and how is it different from chronological age?

Biological age estimates how old your body functions based on lifestyle and biomarker data, while chronological age is simply years since birth. Two 45-year-olds can have biological ages 10+ years apart depending on sleep quality, recovery speed, body composition, and stress levels. This quiz estimates biological age from 7 lifestyle factors correlated with epigenetic aging clocks.

Can you actually reverse your biological age?

Research on epigenetic clocks shows biological age can decrease with interventions including improved sleep, exercise, stress reduction, and certain peptides. Strut's Sermorelin stimulates natural growth hormone production, which declines ~14% per decade and is correlated with biological aging markers. NAD+ levels decline ~50% between age 20 and 50 — supplementation may support cellular repair.

Is this quiz medically accurate?

This quiz provides an educational estimate based on published correlations between lifestyle factors and biological aging markers (DNA methylation, telomere length, IGF-1). It is not a clinical biomarker test. Actual biological age measurement requires lab testing through epigenetic clocks like Horvath's clock or PhenoAge.
