PepTracker: Dose Log
Peptide & GLP-1 Tracker
Only for iPhone
Free · In-App Purchases
Track. Schedule. Never miss a dose.
PepTracker is a dose log and protocol tracker built for peptides, GLP-1 medications, and testosterone. Create structured protocols, schedule injections, calculate exact syringe volumes, and keep a clean record of your progress in one simple app.
What you can do with PepTracker
• Log doses, not guesses – Track every injection with an easy dose log instead of notes or spreadsheets.
• Build peptide and GLP-1 protocols – Create schedules for Semaglutide, Tirzepatide, Retatrutide, BPC-157, AOD-9604, TRT, and more.
• Use the built-in dose calculator – Enter vial amount, diluent volume, and target dose (mg or mcg) to get the exact mL or insulin-syringe units to draw.
• Stay on schedule – Get reminders for upcoming doses and see what’s due today on the Home screen and in the calendar.
• Track progress over time – Log weight and other metrics to see how your protocol is trending.
Made for real protocols
PepTracker works well whether you’re:
• Running a GLP-1 weight loss protocol (e.g., Semaglutide, Tirzepatide).
• Managing peptide stacks for recovery, performance, or wellness.
• Keeping a consistent TRT schedule and dose history.
PepTracker Premium (optional upgrade)
Unlock more structure and flexibility for advanced protocols:
• Unlimited protocols and peptide stacking in a single schedule.
• Advanced scheduling options and extended calendar views.
• Save calculator results directly into protocols.
• Full protocol history plus mood and energy tracking.
• Export logs to CSV/PDF and sync with external calendars (Apple and Google).
PepTracker is built for people who take their peptides and GLP-1 protocols seriously and want a clear, reliable way to stay organized.

more This update brings several improvements to protocol history, calendar tracking, and overall peptide management.
Completed and deleted peptide protocols now remain visible in your calendar, making it easier to review your dose history and keep track of previous cycles. We’ve also added detailed views for completed protocols, so you can reference past compounds, schedules, and protocol information whenever you need it.
You can now restore completed or deleted protocols, making it easy to continue a previous protocol without starting over.
