Free GLP-1 Plasma Level Plotter — No Sign-Up Required
The GLP-1 plasma level plotter is free and always will be. No sign-up. No email. No paywall. No "free trial." Open the page, add your doses, see your curve. That's it.
1) What "Free" Means Here
- Open /plotter, no login screen
- All compounds available: sema, tirz, reta
- Unlimited doses in your log
- Full analytics cards (current exposure, dose rhythm, recent pattern, stat tiles)
- Trend-aware chart coloring
- Multi-compound view if you mix
- URL-share link for sending the chart to your prescriber
- Works on phone, tablet, desktop
2) What's Optional
Two things require sign-in (Google, free):
- Cloud sync — your dose log syncs across devices
- Save calculations — pin specific reconstitution math to your account
Without signing in, your dose log lives in your browser's local storage and persists for ~30 days.
What's Pro (Optional)
If you want to remove the ads that fund the free tools, there's an optional Pro subscription ($2.99/month or $24/year). It removes ads — that's the only difference. The calculator, plotter, titration schedule, and dose conversions all stay free regardless. If ads aren't bothering you, please don't feel obligated.
Why It's Free
Three reasons:
- The math is straightforward. Population PK parameters and a one-compartment absorption model — published in pharmacology textbooks. Charging for the calculation would be charging for arithmetic.
- Free is more useful. A free tool gets used; a $X-per-month tool gets compared, considered, abandoned. People doing GLP-1 protocols benefit from a tool they can actually run, not one gated behind a credit card.
- Ads pay for it. Display ads on free pages plus optional Pro subscriptions cover hosting and time. That's the model.
No Tracking? Let's Be Honest
Two anonymous analytics services run on the page:
- Google Analytics 4 — counts pageviews, anonymized country, device type. No PII.
- Microsoft Clarity — anonymized session recordings of mouse movement and clicks (for UX improvement). No keystrokes are logged.
No data about your specific doses or health is collected, sold, or shared. Read the full privacy policy.

Frequently Asked Questions
Is the GLP-1 plasma level plotter actually free?
Yes, the plotter is 100% free with no sign-up, no email, no paywall, and no free trial. You can open the page, add your doses, and see your curve immediately. All compounds, unlimited doses, full analytics cards, and the share link are available without an account.
What features require signing in on the free GLP-1 plotter?
Only two features need a free Google sign-in: cloud sync, which keeps your dose log consistent across devices, and saved calculations, which pin specific reconstitution math to your account. Without signing in, your log lives in browser storage and persists for about 30 days.
Does the free GLP-1 plotter track my health data?
No specific dose or health data is collected, sold, or shared. Two anonymous services run on the page: Google Analytics 4 for pageviews and Microsoft Clarity for session recordings of mouse movement. No keystrokes are logged and no personally identifiable information is captured.
Why is the GLP-1 plotter free instead of a paid tool?
Three reasons: the underlying math uses published population PK parameters from pharmacology textbooks, free tools actually get used while paid ones get abandoned, and display ads plus an optional Pro subscription cover hosting and time. Pro removes ads but the calculator stays free regardless.
Can I share my GLP-1 plotter chart with my doctor?
Yes. The plotter generates a URL-share link that encodes your dose log into the address itself, so you can send it to a prescriber or save it as a bookmark. The recipient sees the same chart you do without needing to sign up or install anything.
