## [How many units to draw: the reconstitution math, worked out](https://peppytracker.com/guides/peptide-reconstitution-units-to-draw/)

Vial mg, water mL and your dose give you units on a U-100 syringe. The formula, worked examples, and how Peppy's calculator does it for you.

## [Injection site rotation: where to inject next, and how to keep track](https://peppytracker.com/guides/injection-site-rotation/)

Which sites the Wegovy, Ozempic, Mounjaro and Zepbound labels list, why they say to rotate, and how Peppy's body map suggests your next site.

## [Missed a GLP-1 dose? What each label says, and how to keep it from happening again](https://peppytracker.com/guides/missed-glp-1-dose/)

The missed-dose rules from the Wegovy, Ozempic, Mounjaro, Zepbound and Saxenda labels, side by side, plus how Peppy computes missed and overdue and nudges you.

## [GLP-1 titration schedule: the label ladders, and how to track your step-ups](https://peppytracker.com/guides/glp-1-titration-schedule-tracker/)

The dose escalation schedules from the Wegovy, Ozempic, Mounjaro and Zepbound labels, and how Peppy's titration steps advance your dose and mark step-ups on your weight chart.

## [How long does semaglutide stay in your system?](https://peppytracker.com/guides/how-long-does-semaglutide-stay-in-your-system/)

Semaglutide's half-life is about a week, so it takes roughly five weeks to clear. The label numbers for Ozempic, Wegovy, tirzepatide and liraglutide, and Peppy's active-level curve.

## [Tracking GLP-1 side effects and food noise against your dose days](https://peppytracker.com/guides/track-glp-1-side-effects-food-noise/)

What food noise is, how common the GLP-1 side effects are per the labels, and why logging them by dose day matters. Peppy's daily check-in and side-effect heat-map.

## [Peptide tracking spreadsheet vs a pill reminder vs Peppy: an honest comparison](https://peppytracker.com/guides/peptide-tracking-spreadsheet-vs-app/)

What a spreadsheet, a generic pill reminder and Peppy each handle for peptides and GLP-1s: reconstitution math, rotation, cycles, inventory, half-life, reminders and export.

## [Peptide cycle tracker: what "5 on, 2 off" means as a schedule, and how to keep it straight](https://peppytracker.com/guides/peptide-cycle-tracker/)

How on/off peptide cycles work as scheduling, why the off days are where tracking fails, and how Peppy's cycle presets auto-skip off days and show them on the calendar.

## [Peptide stack tracker: run BPC-157, TB-500 and CJC/Ipa as separate protocols with one Today list](https://peppytracker.com/guides/peptide-stack-tracker/)

Track a peptide stack as separate protocols with their own colors, one Today list and site rotation shared across all of them. Peppy for iPhone.

## [Peptide vial inventory: how many doses are left, and roughly when you will run out](https://peppytracker.com/guides/peptide-vial-inventory-tracker/)

Know how many doses are left in each vial and when you'll run out. Peppy counts down every shot you log and reminds you to refill (Pro). Free to start.

## [A weekly injection reminder that follows up if you don't log the shot](https://peppytracker.com/guides/weekly-injection-reminder/)

Shot-day reminders, a missed nudge 30 min, 1 h or 2 h later, a Log it button in the notification and a Lock Screen widget. Peppy for iPhone (Pro).

## [A GLP-1 weight tracker that puts your weigh-ins on the same chart as your doses](https://peppytracker.com/guides/glp-1-weight-tracker-apple-health/)

Log weight in a daily check-in, sync it with Apple Health, and see the trend with a goal line and dose step-up markers. Peppy for iPhone. Logging is free.

## [Dose log export for your doctor: a clean PDF or CSV of what you actually took](https://peppytracker.com/guides/export-dose-log-for-your-doctor/)

Turn your shots, weight and check-ins into a PDF report or CSV before an appointment. Peppy builds it on your iPhone and never uploads it. Export is Pro.

## [A private peptide tracker: no account, your data on your iPhone, synced only with your own iCloud](https://peppytracker.com/guides/private-peptide-tracker/)

Peppy is a peptide and GLP-1 tracker with no account and no server. Logs live on your iPhone and your own iCloud. Apple Health and analytics explained.

## [The best peptide tracker app in 2026: Peppy and eight alternatives, compared from their own sites](https://peppytracker.com/guides/best-peptide-tracker-app/)

Peppy, Shotsy, Glapp, Pep, Dose Track, Peptide Tracker, Regimen, LynkDose and MeAgain compared on compounds, calculator, level chart, platform and price.

## [Compounded semaglutide and tirzepatide units: how the mg on your prescription becomes units on the syringe](https://peppytracker.com/guides/compounded-semaglutide-tirzepatide-units/)

Units = dose in mg ÷ the vial's mg/mL x 100. Worked examples for compounded semaglutide and tirzepatide, why the label's mg/mL matters, and a calculator.

Peppy is a tracking tool, not medical advice. Dose calculations are mathematical conversions only. Always follow your prescriber's instructions and verify every draw-up yourself.

Peppy is a free iPhone app (Pro subscription optional). App Store: https://apps.apple.com/us/app/peptide-tracker-peppy/id6775005514
