How to Use the GLP-1 Plotter
The plotter takes a list of GLP-1 doses and turns it into a plasma-concentration curve over time. This walkthrough covers everything from adding your first dose to interpreting the analytics cards.
1) Step 1 — Pick Your Compound
At the top of the plotter, three tabs: 💉 Semaglutide, 💉 Tirzepatide, 🔬 Retatrutide. Tap the one matching your prescription. This determines the half-life and absorption curve used in the simulation.
2) Step 2 — Open the Dose Log
Click 📋 View / Edit Dose Log. The log table appears with three columns: Date, Compound, Dose (mg).
3) Step 3 — Add Your Doses
Click + Add Dose. A new row appears at the bottom with today's date and 0.25 mg pre-filled. Edit the date, compound, and mg as needed. The new row stays highlighted in indigo until you click outside it (so you don't lose track of what you just added).
Add as many doses as you want — past, present, or planned future doses. The plotter handles them all the same way.
4) Step 4 — Read the Curve
Once you have at least one dose, the chart auto-renders. Key elements:
- Curve line — total plasma concentration over time
- Mg chips on the line at each injection point
- TODAY vertical line — where you are now in the simulation
- Trend coloring — line color reflects rising/stable/declining state
- Today burst — soft halo around the curve where it crosses TODAY
Step 5 — Interpret the Analytics Cards
- Current Exposure — your plasma level today as a % of peak. Includes a trend indicator (↗ rising, → stable, ↘ declining, ↘ rapid decline).
- Dose Rhythm — your typical interval between doses (consistent, mostly consistent, variable).
- Recent Pattern — long-term trend in peak heights (rising, plateau, declining).
- Stat tiles — total doses logged, days tracked, last dose timing.
Step 6 — Save or Share
Three options:
- Sign in with Google → dose log syncs to the cloud, accessible from any device.
- Copy Share Link → encodes your dose log into the URL. Send it to your prescriber or save the link as a bookmark.
- Local browser → if you don't sign in, the log persists in browser storage for ~30 days.
Common Scenarios
- Just started GLP-1? Add your first dose with today's date. Plot will show your accumulation forecast.
- Switching compounds? Add doses with different compound values per row. Multi-compound view shows each curve separately.
- Missed a dose? Just don't add it. Plot will show the trough automatically.
- Microdosing? Add daily small doses. Curve flattens dramatically vs weekly.

Frequently Asked Questions
How do I add my first dose to the GLP-1 plotter?
Pick your compound tab at the top (semaglutide, tirzepatide, or retatrutide), click View / Edit Dose Log, then click + Add Dose. A new row appears with today's date and 0.25 mg pre-filled. Edit the date, compound, and mg as needed, then click outside to save.
What does the TODAY line show on the GLP-1 plotter?
The TODAY vertical line marks where you currently are in the simulation. A soft halo (the today burst) appears around the curve where it crosses TODAY, making your current plasma level visually obvious. This helps you read current exposure relative to upcoming peaks and troughs.
What does the Current Exposure analytics card mean?
Current Exposure shows your simulated plasma level today as a percentage of peak. It includes a trend indicator: rising arrow, stable arrow, declining arrow, or rapid decline arrow. The card helps you understand whether you're approaching a peak, sitting at steady-state, or heading into a trough.
Can the GLP-1 plotter handle switching between medications?
Yes. When you log doses with different compound values per row, the multi-compound view shows each curve in its own color. This is useful for visualizing transitions between semaglutide and tirzepatide or planning a switch with your prescriber based on overlapping plasma levels.
Does the GLP-1 plotter support microdosing protocols?
Yes. Add daily small doses (for example, 0.14 mg daily instead of 1 mg weekly) and the curve flattens dramatically compared to weekly dosing. The plotter handles past, present, and planned future doses identically, so you can compare protocol shapes side by side.
