Virtual Biohacker

An evidence-based longevity model I built for people who think seriously about biomarkers, prevention, and tradeoffs. Compare scenarios. See which levers actually matter — under explicit, provenance-backed assumptions.

The one question it answers

Given your age, labs, risk markers, and the interventions you're weighing — how might plausible changes shift your modeled lifespan, healthspan, and cause-specific risk?

Not a crystal ball

It never claims to know your date of death, and never treats a biomarker score as destiny.

Not a clinician

It does not diagnose or prescribe. It informs the conversation you have with your doctor — it does not replace it.

A structured comparison

Its value is letting you weigh scenarios under explicit, evidence-graded assumptions and see which levers matter most.

Inside the app

Tune your inputs. Watch the model recompute.

Nine domains of inputs — labs, fitness, nutrition, sleep, substances, meds, conditions and more — each one feeding a population-grounded estimate that updates live.

Labs & Biomarkers screen — ApoB, Lp(a) and Omega-3 Index sliders with evidence citations
Labs & Biomarkers

31 markers, each with its evidence.

Every marker sits on a −1…1 scale with your measured value marked. Drag any slider to model a better number — and each one cites its source (ApoB · Sniderman 2019, per-SD HR ≈ 1.3).

Meds & Stack screen — pharmacologic intervention toggles grouped by axis
Meds & Stack

33 controls across six axes.

Statins, antihypertensives, metformin, SGLT2s, tirzepatide and more — modeled as levers. Gated items unlock only with the condition that warrants them.

Conditions screen — clinical indication checkboxes with inline AFib management control
Conditions

Indications gate the right levers.

Checking a clinical condition reveals its condition-specific entities inline — GLP-1 for type 2 diabetes, ctDNA after prior cancer, an anticoagulation control for AFib.

Conditional controls screen — sex-gated treatments shown locked with reasons
Honest gating

Locked when it shouldn’t apply.

Sex- and condition-gated controls render disabled with a lock and a plain-language reason — no false options, no levers you can’t actually pull.

About You — set your whole baseline at once by importing JSON your AI builds from an instruction sheet
AI-assisted setup

Set your whole baseline in one import.

Download an instruction sheet, hand it plus your records to ChatGPT, Claude or Gemini, and paste back the JSON. The app never parses raw reports — your AI builds the baseline, you confirm every value.

How it works

Inputs in. Modeled scenarios out.

01

Set your baseline

Import it in one step — your AI builds the JSON from an instruction sheet — or enter it directly across nine domains of demographics, labs, fitness, and behavior.

02

Choose your levers

Toggle the interventions and conditions you’re weighing, from proven basics to experimental compounds. Gated levers unlock only with their indication.

03

Read the forecast

See a median lifespan and healthspan estimate with an uncertainty envelope, plus your top priorities ranked by the months each one is modeled to add.

What every result carries

A number you can actually trust.

You never get a lone exciting figure. Every modeled result shows its work.

Baseline & deltas

A grounded starting point, then the modeled change each lever produces.

Uncertainty range

Every estimate ships with a plausible range — never a false-precision single number.

Evidence class

T1–T4 grading on every lever, so you know proven from promising from provisional.

Cause-specific risk

Endpoints are labeled — all-cause vs. cardiovascular, metabolic, and more.

Provenance & safety

Coefficient provenance and safety/monitoring context behind each result.

Healthspan, not just lifespan

Models years of healthy function, not only total years.

Questions, answered.

What does the application tell me?

The Virtual Biohacker takes your inputs on demographics, health, labs, activity, and other measures proven to impact longevity, and gives back a science-backed, standards-based population median lifespan / healthspan estimate. It then prioritizes the interventions you can implement to move the needle on that estimate.

What’s the difference between Basic and Advanced?

Basic lets you model science-backed traditional interventions like diet, exercise, treating disease, and supplementation. Advanced activates all evidence-backed advanced / biohacking interventions and helps you understand the results possible with leading-edge protocols. Advanced also adds capabilities around reporting and scenario modeling.

Is this medical advice?

No. The Virtual Biohacker is not a medical tool and does not predict individual results. It uses recognized scientific sources — NHANES, WONDER, and published research studies — along with other population health data to produce scenarios, similar to how insurance companies model risk using the same tools.

How does billing work?

Numerous subscription options are offered; choose the one that works for you. Once paid, your current subscription is non-refundable, but you can turn off renewals at any time.

Honest by design

Virtual Biohacker models scenarios under explicit assumptions. It does not predict your date of death, does not treat a biomarker as destiny, and does not replace a clinician, a diagnostic workup, or shared decisions about medication. It's a thinking tool I hold to an evidence standard. [Placeholder — counsel-reviewed disclaimer pending.]
