Log every dose, track your weight loss over time, monitor side effects, and see how your medication is affecting your body composition, energy, and sleep — all synced automatically from Apple Health or Google Health Connect. Whether you're on Ozempic, Wegovy, Mounjaro, Zepbound, or compounded semaglutide, Regimen tracks it — with half-life data 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.
GLP-1 medications work. Tracking them shouldn't be hard.
Whether brand or compounded, the same problems surface:
Managing weekly injection timing across different GLP-1 compounds when you've switched brands or are comparing options
Losing track of your titration progress — especially on compounded versions without auto-shipped dose steps
No clear way to correlate your weight loss with specific doses, timing changes, or diet adjustments
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.
