The medication-level view plots an estimated level curve from the doses you have logged and the compound's published half-life — showing accumulation, overlaps, and decay over time.

In plain terms: it turns "half-life = 7 days" into a picture of what your own logged doses add up to.

What it computes

Using the half-life of the compound and the timing of your logged doses, the app models the rising-and-falling curve — including accumulation toward steady-state when doses repeat. Two models are available for different pharmacokinetic shapes.

What the curve shows

  • The estimated level now and over time.
  • How doses stack when they overlap.
  • The dip a missed or late dose creates.
  • For a stack, overlaid curves for multiple compounds.

Its honest limits

The curve is an estimate, not a measurement. It uses population half-life values and transparent models — real individual pharmacokinetics vary with route, formulation, and physiology. The app labels it "estimated level" deliberately; it is a model of the concentration curve, not your actual blood level. For compounds with a PK-PD disconnect — where the drug clears the blood but its effect lingers — it does not claim to represent *effect* at all.

In plain terms: it is an honest model of the level trend, not a lab reading of your blood.

Why it beats a static number

"Half-life = 7 days" is a fact; a curve built from *your* logged doses shows what that fact means for *your* timeline — which is the useful part. It is only as good as the log, which is why accurate dose logging matters.

The curve is an educational model, not medical advice or a measurement. Open Zyra Labs to see it build from your log.
