Free for everyone." --- 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. [Get GLPMate free](/download) [Open the web plotter](/tools/glp-1-plotter) Estimated medication level 90 % of steady state Right now · semaglutide 1 mg weekly Free __Recorded __Projected __Steady state Modeled on FDA clinical-pharmacology data Quick answer 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 Tirzepatide · titrating 84 % of steady state Deeper troughs — a 5-day half-life looks different Free __Recorded __Projected __Steady state Modeled on FDA clinical-pharmacology data ### 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 Method, openly ## 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. [Read the methodology →](/science) 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. FAQ ## 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. ## See your curve today. Log your last dose and the model does the rest. Free, iOS & Android.
