Peppy
Peptide & GLP-1 tracker for iPhone
Never miss a shot.
Know what it's doing to you.
Peppy does the math: units to draw, next shot, site rotation, dose step-ups and what's still active in your body. 123 compounds built in. Private on your iPhone.

How it works
Pick a compound. Peppy handles the schedule, the math and the reminders.
Search your compound
Ozempic, compounded tirzepatide, BPC-157, CJC/Ipa. Form, unit, typical frequency and dose steps come prefilled. Protocol setup is a search, not a form.
Enter the vial, get the units
Vial size, water added, your dose. Peppy shows the units to draw on a U-100 syringe and warns when a dose will not fit. Doses left and the day you run out are counted for you.
Log in one tap, on the body map
Shot day counts down on the Today tab. Tap the site Peppy suggests, add a note, done. Side effects, weight and how you feel sit next to every dose.
Two ways people use Peppy
One weekly shot, or a whole stack.

Each compound has its own page with the calculator, the typical schedule and, where the catalog lists a half-life, the "active in your system" chart.
Private by design
Lives on your iPhone, synced with your iCloud. No account, no Peppy server, no ads. Face ID lock optional.
