Regimen tracks tirzepatide across branded Mounjaro, branded Zepbound, and compounded versions in one app. Six pen strengths (2.5, 5, 7.5, 10, 12.5, 15 mg) for branded, plus flexible mg-per-dose logging for compounded. Side-effect tracking across 50+ markers, lab integration, and Apple Health and Google Health Connect sync. Multi-compound friendly. Free for one compound; Pro is $4.99/month.
Daily, weekly, EOD, custom, as-needed. Stay consistent with smart reminders for every cadence.
Set your cycle duration and get alerts when it's time to cycle off, take a break, or restart.
Reconstitution, reverse BAC, TRT oil, and intranasal. Regimen handles the complex math, so you don't have to.
Track your vials, pens, and pills. We'll let you know when you're running low.
Regimen connects your doses, levels, check-ins, and blood work to what actually changes in your protocol. Measured against your own baseline, not population averages.
What's helping, what's not, and what's worth keeping an eye on.
Watch your weight and body fat move. See the line bend.
Track your progress over time. Before and after comparisons, week-by-week change, and multi-angle views.
Sleep, resting heart rate, blood pressure, a lab value. Watch your trend.
Compounded tirzepatide comes in varying concentrations. Regimen handles the math from your specific vial strength to exact syringe units.
Without auto-shipped pens, you're managing your own step-ups. Regimen tracks your dose history and flags when your next step-up is due.
See exactly how each dose change impacts your weight, appetite, and energy: the data that tells you whether a step-up is actually helping.
Enter your vial concentration (mg/mL), the bacteriostatic water you added, and your target dose in milligrams. Regimen converts that to exact units on a U-100 insulin syringe and saves the recipe so you only do the math once per vial.
Yes. Pen Mounjaro and Zepbound log by strength; compounded tirzepatide logs by mg per dose since vial concentrations vary. Switching between branded and compounded keeps your weight trend, side-effect history, and labs continuous.
Yes. Split dosing (half your weekly dose every 3.5 days) and daily microdosing are fully supported. The PK model accounts for the actual cadence, so blood-level estimates and side-effect timing line up with what you are really doing.
Yes. CGM data (Dexcom, Libre) and fingersticks both log to the same view. HbA1c, fasting glucose, and time-in-range plot against your dose timeline so you can see whether titration is actually moving the numbers.
GI symptoms (nausea, vomiting, diarrhea, constipation, sulfur burps, reflux), plus fatigue, sleep quality, mood, appetite intensity, food aversion, and the food-stuck feeling. Custom markers cover injection-site reactions or birth control backup windows after each titration step.
See the comparison table above. Short version: those apps are GLP-1-only logs. Regimen handles tirzepatide alongside any other compound, models blood levels with published PK data, and includes lab correlation on the free tier.
Yes. The free tier covers one compound, including tirzepatide, with full dose logging, glucose, side effects, weight sync, and lab tracking. Pro ($4.99/month) unlocks multi-compound stacks and the Signals pattern engine.
The underlying compound is the same, so the PK math is identical. The difference is framing per view: Mounjaro surfaces HbA1c and glucose, Zepbound emphasizes weight trajectory and body composition, and the tirzepatide view stays neutral for compounded dosing. Your data flows the same way across all three.
