What moves the number

Biological age isn't fixed. Four things move it most.

Your chronological age only counts birthdays. Biological age reflects how your body is actually doing, and unlike the calendar, it responds to what you do.

Metabolic health

Blood sugar, insulin response, and body fat distribution are among the strongest movers of how your body ages.

Inflammation

Chronic low-grade inflammation quietly accelerates aging. Lowering it is one of the most actionable levers you have.

Muscle & body composition

Lean mass protects your metabolism and your independence. Holding muscle is holding the number down.

Sleep & recovery

Deep, consistent sleep is when repair happens. Poor recovery shows up in the number faster than almost anything.

Measuring where you stand

The honest state of measuring biological age.

The science of biological-age testing is real but still maturing, so we'll tell you exactly what's solid and what isn't.

What's solid today

The biomarkers that drive aging, metabolic, inflammatory, body-composition, and recovery markers, are well-established and trackable with standard labs your clinician can order.

What we don't oversell

Single-number "biological age" tests vary by method and aren't a finish line. We focus on the markers you can actually move, and we frame everything as improve and support, never reverse or guarantee.

On our roadmap, flagged honestly

A dedicated Peptós.LIFE biological-age diagnostic is on our roadmap, not live yet. Until it is, we work from the established markers above rather than claim a test we don't offer. When it ships, members hear first.

The markers we track

Longevity isn't a vibe. It's a panel of numbers you can actually move.

A serious program starts with a baseline. These are the markers a whole-health panel tracks to understand metabolic health, hormones, and recovery, and to know whether a plan is working.

HbA1c

Your average blood sugar over ~3 months, a core read on metabolic health.

Fasting insulin

How hard your body works to manage glucose, often shifting before HbA1c does.

Lipid panel (incl. triglyceride-to-HDL)

Cardiometabolic risk at a glance; the triglyceride-to-HDL ratio tracks insulin resistance.

Testosterone (total + free)

Energy, strength, and recovery signal, measured as both total and the free, active fraction.

Estradiol

A key hormone in metabolism, bone, and mood across the perimenopause and menopause transition.

The whole-health panel

Inflammatory, thyroid, and recovery markers round out the picture your clinician builds the plan from.

Labs are recommended, never required. These markers are for tracking and personalization, not a diagnosis or a treatment-outcome promise.

Go deeper

The mechanism, for those who want it.

Most approaches combine biomarkers, metabolic, inflammatory, and sometimes epigenetic (DNA-methylation) signals, into a composite estimate. Methods differ, which is why the single number varies between tests. The underlying markers are the durable, actionable part.
A model that reads chemical methylation marks on DNA and correlates their pattern with age. They're a promising research tool, but methods and outputs differ between clocks, useful as a trend signal, not a verdict. We treat them as one input, not the answer.
Inflammatory markers and metabolic markers (like fasting glucose and insulin response) often move first with a consistent protocol, followed by body-composition changes. Recovery and sleep metrics tend to improve early and reinforce the rest.
That the drivers, metabolic health, inflammation, muscle, sleep, are modifiable and matter. We keep claims within each intervention's evidence grade and frame outcomes as improvement and support, not a guaranteed change to any single age number.

Questions

The honest answers.

You can improve the markers that drive it, metabolic, inflammatory, body-composition, and recovery measures. We frame this as improvement and support, and we don't guarantee a change to any single “age” number. The honest goal is moving the things you can actually move.
No. We work from established, trackable biomarkers your clinician can order. A dedicated NAM diagnostic is on our roadmap, but it isn't required, and we won't gate you behind a test we don't yet offer.
We build a personalized, supervised protocol at an accessible monthly price instead of thousands up front, and we re-measure on a cadence so the plan adjusts as you do. It's the accessible-concierge middle, not a boutique clinic.
Compounded medications are not FDA-approved. They're prepared by licensed pharmacies for an individual patient when a clinician determines they're appropriate. We state this plainly, nothing hidden.
