VIAL & SYRINGE TRACKING
Log the Dose You Actually Drew
Compounded semaglutide and tirzepatide come in vials, so every dose is a number of units on a syringe rather than a click on a pen. Pep logs the dose in mg or units, the site you used, and the date, and reminds you when the next one is due.
MEDICATION LEVEL
See Where You Are Between Doses
Compounded semaglutide and tirzepatide behave like their branded versions between doses: semaglutide stays active for about a week, tirzepatide for about five days. Pep’s medication-level indicator shows the active window, and the calendar lays out every dose and habit so you can connect how you feel to where you are in the cycle. Curious what your curve looks like today? Try the free medication level calculator.
PROGRESS & NUTRITION
Track the Results, Not Just the Doses
Weight, measurements, and photos show the long arc; protein, fiber, calories, and water show whether the daily routine is holding up. Pep keeps all of it next to your dose log, with a food database, barcode scanner, and AI food scanner so logging takes seconds.
Compatible GLP-1 Medications
Pep supports compounded semaglutide and tirzepatide alongside every branded GLP-1. If you move between compounded and branded, your history stays in one place.
Why Use a Compounded GLP-1 Tracker App?
Compounded GLP-1s add a layer of arithmetic that branded pens hide. Your prescription is in milligrams, your vial is labeled in mg per mL, and your syringe is marked in units, so every dose is a conversion. Our free units calculator turns your prescribed mg into units for your vial’s concentration, for both semaglutide and tirzepatide. Pep then logs the dose you drew, so if a prescriber, pharmacy, or concentration changes, your record stays accurate.
Tracking matters more with compounded medication because the details vary. Concentrations differ from pharmacy to pharmacy, some prescribers escalate on the branded schedule and others more slowly, and vials have beyond-use dates. Pep records the dose, date, and site of every injection and lets you note side effects the day they happen, which is exactly the record a prescriber wants to see at a follow-up. Our dose schedule calculator maps the branded step-up dates for reference.
Two things worth knowing: compounded GLP-1s are not FDA-approved products and are not identical to branded pens, so follow your prescriber’s and pharmacy’s instructions over any general guidance, including ours. And if a dose is late, the branded labels are the usual reference point; our missed-dose calculator shows what they say for semaglutide and tirzepatide by how many days have passed.
