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.

What GLP-1 protocols actually need to track

Six things that distinguish a usable GLP-1 tracker from a generic medication app.

CadenceWeekly subcutaneous, on the same day if possible — Peptide Protocol fires a gentle reminder and pins the next dose to your home-screen widget
EscalationFDA-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 mathVial-aware presets — pick your vial mass and BAC water volume, the calculator outputs U-100 / U-50 / U-30 syringe units instantly
Site rotationBody-map with 48–72 hour cooldowns; for weekly GLP-1 this is light-touch but still tracked
Weight chartInsights overlay weight against the dose timeline — see when each escalation step actually started moving the chart
GI side-effect logDaily 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.

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.

Not medical advice. Peptide Protocol is a personal tracking tool — it does not diagnose, prescribe, or replace a clinician. GLP-1 medications including Tirzepatide and Semaglutide are prescription-only in most jurisdictions. Always consult a licensed healthcare professional before starting, modifying, or stopping any compound.
