Track Your Semaglutide Protocol
Log every dose, see your weight loss trend, and know exactly how your body responds at each titration step.
Semaglutide — Compounded & Brand GLP-1
Regimen is the best semaglutide tracker app for people who want more than a dose reminder. Log your Ozempic, Wegovy, or compounded semaglutide doses, track your weight loss over time, monitor side effects during titration, and see how your semaglutide is actually affecting your body composition, sleep, and energy. Regimen connects your doses to your health data — automatically synced from Apple Health or Google Health Connect — with half-life modeling sourced from published clinical studies and FDA prescribing information. Free — every feature unlocked for your first medication. No paywall, no trial, no credit card. Rated 4.9 stars on iOS and Android.
Compounded semaglutide adds a layer of complexity.
Brand pens are straightforward. Compounded vials are not:
Calculating the exact syringe draw from your vial concentration — and second-guessing the math every single time
Tracking how many doses are left in your vial and when you need to reorder before you run out
Trying to compare your progress on compounded semaglutide when most resources only reference brand-name dosing
Dose with precision
Regimen handles the complex math so you don't have to. Two built-in calculators give you exact numbers every time.
Peptide reconstitution calculator
Input your vial size, bacteriostatic water volume, and desired dose. Regimen tells you exactly how many units to draw on your syringe.
mL dose calculator
Enter your prescribed dose (mg) and concentration (mg/mL) to get the precise injection volume. Perfect for testosterone and oil-based compounds.
Never miss a dose. Never miss a cycle.
Stay consistent with zero effort. Regimen supports every dosing schedule you could need, with smart reminders to keep you on track.

See what's actually working
