Medication level · free for everyone
Know what's in your system. Free.
Your body doesn't reset between injections — medication accumulates, peaks and dips on a rhythm. GLPMate models that rhythm from your real doses, so shot-day highs and pre-dose trough days finally make sense.
A GLP-1 medication-level tracker estimates how much active drug is in your body between doses. GLPMate models it per medication from FDA pharmacology parameters and your real dose log — showing dose-day peaks, trough days and your progress toward steady state. In GLPMate this is a free feature, for every medication.
Cadence-aware, not calendar-naive
Most level widgets assume a perfect weekly schedule. Real life isn’t perfect — GLPMate computes from the doses you actually logged, at the times you actually took them.
- Weekly, every-10-days, bi-weekly or custom — the model follows your real rhythm
- Titration steps re-shape the curve automatically
- Missed or late doses show up honestly instead of being smoothed away
Steady state, demystified
“Give it four weeks” makes more sense when you can watch the accumulation happen. The band on the chart is the destination; your curve is the journey there.
- A visible steady-state band shows where your curve is heading
- A plain-language status line: “approaching steady state”
- Each dose increase restarts the climb — and the chart shows it
The science is public. So is ours.
One-compartment model, first-order absorption, parameters from FDA clinical-pharmacology reviews. We publish the method on our science page — because a health tool you can’t interrogate is just vibes.
The level curve is an educational estimate of relative levels — not a measurement, not a medical device, and never a basis for changing your dose. Dosing decisions belong to you and your prescriber.
Level-curve questions
How does GLPMate estimate my medication level?
With a standard pharmacokinetic model (one-compartment, first-order absorption) parameterized per medication from FDA clinical-pharmacology data — half-life, time-to-peak — and driven by your actual logged doses and cadence. It’s an educational estimate, not a blood measurement.
Why do I feel different on shot day than the day before my next shot?
Your level peaks 1–3 days after a weekly injection, then declines toward a trough before the next dose. Many people notice appetite, energy and side effects tracking that curve. Seeing your estimated position on it turns “why do I feel off today?” into “ah — trough day.”
What is steady state?
The point where drug intake and elimination balance out, so your weekly curve repeats in a stable band — typically after 4–5 half-lives at the same dose (about a month for semaglutide). GLPMate shows the steady-state band and how far along you are.
Does the curve handle dose changes and unusual schedules?
Yes — that’s the point. Titration steps, missed doses, 10-day cadences, micro-dosing: the model re-computes from your actual dose history, not an idealized calendar.
Is the level curve really free?
Yes, for every supported medication, forever. Some competitors put their (simpler) version behind a paywall; we think understanding your own medicine is a right, not an upsell.
Can I try it without installing anything?
Yes — the free web plotter at /tools/glp-1-plotter runs the same class of model in your browser. The app version updates automatically from your logged doses.
