Transcriptomic biological aging assay

Not just your biological age. Your biological direction.

BeyondAge measures how your cells respond under simulated microgravity to reveal where aging may be accelerating.

Born in space. Crafted in California. By Cosmica Biosciences · built on the science of the Buck Institute
Why BeyondAge

Most aging tests measure a snapshot. BeyondAge measures response.

By comparing your cells before and after simulated microgravity, BeyondAge identifies the biological systems most likely to drive accelerated aging over time.

A measure of how your biology responds — not a single-timepoint score.

  • 01

    Current biological age

    How your biology compares to your chronological age today.

  • 02

    Projected aging trajectory

    How your cells respond under accelerated-aging conditions.

  • 03

    Top aging drivers

    The pathways and hallmarks contributing most to your risk profile.

  • 04

    Retesting over time

    Track whether interventions are shifting your biological response.

We go far beyond

Beyond a clock — a transcriptomic readout of cellular aging.

20,000+
transcripts analyzed
01

Thousands of transcripts

We measure gene-expression patterns across 20,000+ transcripts — not a single biomarker score.

02

Developed from Buck Institute research

Built on aging biology and microgravity research developed with scientists at the Buck Institute.

03

Processed under research protocols

Samples are handled by trained scientists under standardized protocols for high-resolution transcriptomic analysis.

04

Through select clinics

Available through select longevity and preventive-health clinics.

How it works

One blood draw. Two biological states. One aging trajectory.

Your sample is analyzed at baseline and again after 24 hours in simulated microgravity — a before-and-after view of how your cells respond.

01 Blood draw via your clinic 02 Microgravity 24h immune-cell culture 03 Transcriptomics gene-expression readout 04 Report age + hallmark scores
01

Blood draw

A simple blood sample, via your clinic or an approved collection pathway.

02

Simulated microgravity exposure

Your immune cells are cultured for 24 hours in a simulated microgravity environment.

03

Transcriptomic sequencing

Gene-expression changes are measured across thousands of transcripts.

04

Aging trajectory report

Results are mapped to biological age, hallmark-level scores, and priority intervention areas.

What we measure

Fourteen hallmarks of aging, from your cellular response.

BeyondAge maps transcriptomic changes to hallmark-level aging pathways, helping identify which biological systems appear most accelerated.

The fourteen hallmarks of aging measured by BeyondAge, arranged around an infinity loop: mental and physical ability, cellular age, telomere health, stem cell health, senescence, protein health, nutrient sensing, mitochondrial health, metabolic health, cellular communication, immune health, epigenetic health, inflammation, and resilience.

Scores are calculated at baseline and after simulated microgravity. The change between states helps estimate trajectory.

Biological direction

From static age to biological direction.

BeyondAge is designed to show whether your biology appears stable, resilient, or accelerating under stress — and which systems are driving that pattern.

BeyondAge is available through approved partner clinics.

For clinics

Partner with us

Offer a differentiated biological aging report, built on transcriptomic response — not standard lab markers alone.

For research partners

Study with BeyondAge

Use BeyondAge to study intervention response, aging trajectories, and cellular resilience.

Aging is not a snapshot — it is a trajectory. BeyondAge was created to reveal where your biology may be headed, so we can move from simply measuring health to anticipating risk and changing its course.
