Tirzepatide tracker
for iPhone.
Tirzepatide on a weekly schedule looks simple on paper — one shot, every seven days — and quickly stops being simple in practice. Doses escalate. The reconstitution math depends on the vial you got. Side effects ride the dose-up weeks. Peptide Protocol is built for exactly this: a calm iPhone tracker that knows your escalation, draws the math, surfaces the side-effect pattern, and never lets you guess what week you're on.

| Class | Dual GIP/GLP-1 receptor agonist (incretin mimetic) |
|---|---|
| Brand names / aliases | Mounjaro, Zepbound, LY3298176 |
| Regulatory status | FDA-approved (Mounjaro / Zepbound) |
| Evidence level | Official label |
| Plasma half-life | ≈5 days (~120 hours) |
| Approved presentation | Pre-filled, single-dose pen (Mounjaro for type 2 diabetes; Zepbound for chronic weight management and obstructive sleep apnea in adults with obesity). Some single-dose vial presentations exist in certain markets but the approved product is not a generic reconstituted research vial. |
| Dose initiation | 2.5 mg once weekly for 4 weeks, then 5 mg once weekly; further escalation per FDA label. |
| Escalation | 2.5 → 5 → 7.5 → 10 → 12.5 → 15 mg, weekly steps held a minimum of 4 weeks each per Mounjaro/Zepbound label. |
| Common stack pairings | Cagrilintide (CagriSema-style fixed-dose pattern, investigational) |
| Side-effect notes | GI effects (nausea, diarrhea) common during dose-up weeks; class boxed warning for rodent thyroid C-cell tumors. |
| Key caveat | FDA-approved Mounjaro / Zepbound ship as pre-filled pens — no reconstitution. Compounded Tirzepatide from a 503A compounding pharmacy may ship as a vial requiring user-mixed reconstitution; that is not the same product as the FDA-approved label. |

Built around Tirzepatide protocols
Three things the app does that a spreadsheet, the manufacturer pen, or a generic reminders app won't.
Knows your escalation week
Add the 2.5 → 15 mg ladder once. The app increments your target dose automatically every 4 weeks (or whatever cadence you set) and the calculator output stays in sync — no edits, no guesswork on dose-up day.
Reconstitution math (compounded vials)
For compounded Tirzepatide vials, enter the vial mass and BAC water volume you used. The app shows the exact U-100 / U-50 / U-30 unit count to draw for your current dose. For FDA-approved Mounjaro / Zepbound pens, the math is built into the pen — the app simply tracks the dose you took.
Side-effect log next to the dose log
The daily check-in captures appetite, energy, sleep, weight, and free-text notes. The weekly report puts the 7-day symptom pattern next to the dose timeline so you can see — and show your clinician — exactly how each escalation step landed.
What it looks like
Tirzepatide tracking — common questions
Does Peptide Protocol have a Tirzepatide preset?
It depends on what form you have. FDA-approved Mounjaro and Zepbound ship as pre-filled, single-dose pens — no reconstitution math is needed; the app tracks dose, schedule, weight progress, and side-effects. If you have compounded Tirzepatide from a 503A pharmacy in vial form, the calculator handles the reconstitution math from your specific vial concentration and BAC water volume.
How do I track a Tirzepatide escalation schedule?
When you build the protocol, set the starting dose (typically 2.5 mg) and add scheduled step-ups every 4 weeks (5 mg → 7.5 mg → 10 mg → 12.5 mg → 15 mg). The app increments the target dose automatically on the scheduled date and updates the calculator output, so the next draw is always correct without manual edits.
Can the app track Tirzepatide GI side effects between doses?
Yes. The daily check-in captures appetite, energy, sleep, and weight on a 0–10 scale, plus free-text notes for nausea, GI discomfort, or other effects. The weekly report aggregates the 7-day pattern next to your dose log so you can correlate symptom days with each escalation step.
