Peptide Protocol
for GLP-1 patients.
Whether your doctor wrote a prescription for Wegovy, you're sourcing Tirzepatide for compounded use, or you're early on Retatrutide — the GLP-1 family shares a workflow. Once-weekly cadence, four-week escalation steps, GI side effects in the dose-up weeks, and a weight chart that takes a month to start meaning anything. Peptide Protocol holds all of it on one screen, on your iPhone, with no account.
Download Peptide Protocol — FreeWhat GLP-1 protocols actually need to track
Six things that distinguish a usable GLP-1 tracker from a generic medication app.
| Cadence | Weekly subcutaneous, on the same day if possible — Peptide Protocol fires a gentle reminder and pins the next dose to your home-screen widget |
|---|---|
| Escalation | FDA-labeled ladders for Tirzepatide (2.5 → 15 mg) and Semaglutide (0.25 → 2.4 mg); custom ladders for Retatrutide. Step-up dates handled automatically. |
| Reconstitution math | Vial-aware presets — pick your vial mass and BAC water volume, the calculator outputs U-100 / U-50 / U-30 syringe units instantly |
| Site rotation | Body-map with 48–72 hour cooldowns; for weekly GLP-1 this is light-touch but still tracked |
| Weight chart | Insights overlay weight against the dose timeline — see when each escalation step actually started moving the chart |
| GI side-effect log | Daily check-in with appetite, energy, sleep, free-text notes; the weekly report aggregates so the dose-up weeks don't blur |
Built for the GLP-1 workflow
Three features that matter especially if you're running a GLP-1.
Knows your escalation week
Lay out the dose ladder once. The app advances you on schedule, recomputes the calculator output, and adjusts the home-screen widget — no manual edit on dose-up day.
Weight + GI log on one timeline
The Insights tab puts your weight chart, adherence streak, and GI symptom days on a single timeline. The thing your clinician asks about ("how did the 5 mg week go?") is one screenshot away.
Apple Health, opt-in
Write weight and vitals to Apple Health if you want, read weight back so the chart stays in sync if you're already tracking elsewhere. Default is on-device only — no cloud sync, no account.
What it looks like
GLP-1 tracking — common questions
Does Peptide Protocol work for both Tirzepatide and Semaglutide?
Yes — both are first-class presets in the calculator, with their own published escalation ladders. The same workflow extends to Retatrutide and any other GLP-1 you run. The app handles weekly cadence, dose escalation, weight charting, and GI side-effect logging the same way across the family.
Will it sync with Apple Health?
Yes. Sync is opt-in per category — write your weight and check-in vitals to Apple Health, read weight back so the chart stays in sync, and revoke access at any time in iOS Settings. No cloud account required.
Can I share a clinician-friendly report from the app?
Yes. The weekly report includes adherence, dose timeline, weight delta, side-effect notes, and inventory status. From Settings → Export you can also download a CSV or JSON of the full history. Both are useful when checking in with a telehealth provider or primary-care physician between escalations.
