Personal health intelligence

Know what your stack is doing to your blood.

BioStack checks every supplement, medication and compound you log against each other, reads your lab results in that context, and shows how each marker moves over time — so the conversation with your doctor starts from data, not guesswork.

How it works

Five instruments, one record of you.

  1. 01

    Stack

    Log it once.

    Prescriptions, supplements, peptides and performance compounds, with dose, route and timing. Every pair is checked against an interaction rule set the moment you add it.

    Bloodwork

    Photograph the lab report.

    Markers are extracted for you to review before anything is saved, then read against sex-specific reference ranges — and against what you are taking.

    Trends

    Watch the lines, not the snapshots.

    Any marker you test twice becomes a chart with its reference band, so drift is visible long before it turns into a flag.

    AI Architect

    Ask with your whole context loaded.

    Questions are answered with your profile, stack and labs in view, streamed as they are written. A thinking partner — not a prescriber.

    Should I retest HDL before changing anything?

    Your HDL fell 9 mg/dL since March. A retest 6–8 weeks after any change shows…

Evidence

Graded, refreshed, and actually cited.

Every compound in the protocol library carries an evidence grade that is re-checked against PubMed on a schedule. A citation only appears if the paper was actually retrieved — a language model cannot slip in a reference that doesn't exist.

Questions

Is this medical advice?

No. BioStack organises your own data and flags known risks; decisions about medication belong with a licensed clinician. The doctor report exists to make that conversation shorter and better informed.

Who can see my data?

You. Health data is processed under your explicit consent (GDPR Art. 9), is never sold, and can be exported or deleted from Settings at any time. AI features send only the context an answer needs to our AI model provider.

Do I need to be on performance compounds?

No. Most of what BioStack checks is everyday: supplements, prescriptions, over-the-counter medicine, caffeine and alcohol. Performance compounds are supported, not assumed.

Which labs can it read?

Any report you can photograph. Extracted markers are shown for you to confirm or correct before saving, and every value can also be entered by hand.
