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.

This has the makings of a great app. Easy to use and has most of the features I want. The updates I’m looking forward to are the abilities to log doses in previous months and the ability to track more than 3 peptides. I also would love the ability to set start dates and durations for the peptides protocols. A place to track injection sites and make notes on side effects or results would be great too. But great start.
Developer Response
Thanks for writing this out— super helpful! Totally hear you on logging past doses, tracking more than 3 peptides, and adding start dates/notes. Those are all on the way soon (a lot tied to PepTracker Premium). Appreciate you taking the time to share— and if you ever want to send more ideas, shoot us a note at support@peptracker.app.
Really good start!

A few bugs here and there (marking a dose as taken sometimes doesn’t seem to save). But the app looks great and does a ton of useful stuff. Keep up the good work! I’d happily pay a monthly or yearly subscription for more protocols and features. A reverse bac calculator would be great too (where I can say how many mg and u it’s I want and it will tell me how much bac to use).
Developer Response
Appreciate you calling this out— super helpful feedback. A few users have mentioned the “mark dose taken” bug with protocols, so I’m working on squashing that. Premium will bring unlimited peptide protocols and more advanced features (like start dates and extended logging). I also love the idea of a reverse bac calculator— inputting your target mg or units and getting the bac water amount back is something I’ve had on the roadmap. Thanks again for the review, and for pushing PepTracker to become the best dose calculator + GLP-1 peptide tracking app out there.
The BEST app for GLP-1/peptide tracking
Beaver_Searsn
Basically what the title says. This IS the best app I’ve found for tracking semaglutide, tirzepatide, and other peptides. The reminders keep me on schedule and the weight loss tracking is super motivating. Way better than using notes or spreadsheets and all the other peptide related apps I've tried on here. Love it!!.
Developer Response
Thanks so much for this! PepTracker was built to make GLP-1 and peptide tracking simple—whether you’re logging Semaglutide, Tirzepatide, Retatrutide, or stacking multiple protocols. Really glad the reminders and weight tracking are helping you stay on schedule. Hearing that it’s better than spreadsheets and other peptide apps makes all the late nights worth it. Appreciate you taking the time to share your experience!
Incredible

I don’t ever leave reviews but man this app is awesome! Passes the eye test for sure and is incredibly useful!Doesn’t seem like the units function is working and really need to be able to track more than 2 protocols but otherwise absolutely amazing!
Developer Response
Thank you so much for the kind words— means a lot! 🙌We're glad you're finding PepTracker useful and totally hear you on both points:– Multi-protocol support is coming VERY soon (within the next week or two)!– As for the units function, we’d love to understand what’s not working for you— feel free to shoot us a note at support@peptracker.app so we can take a look and get it fixed.Appreciate you taking the time to review— it helps a ton!
Big update.
This release introduces vial tracking, protocol cycling, and a number of improvements to how you build and manage your peptide and anabolic protocols.
You can now track your vial supply, including dose, draw, concentration, and remaining doses directly within your protocol. On/off cycling has also been added, making it easier to manage structured cycles over time.
Protocol setup has been improved across the board with a new protocol details screen, better scheduling inputs, and a smoother experience when selecting peptides and anabolics.
Also includes UI improvements, expanded compound options, and more control over calendar sync.
If you run into any issues or have feedback, you can report a bug or contact support directly in the app, or email support@peptracker.app — I read and respond to every message. You can also request new features there as well.
Thanks for your trust.
