Track Your Tirzepatide Protocol

Log Mounjaro or Zepbound doses, monitor your weight at every titration step, and see your results clearly.

Tirzepatide — Compounded & Brand GIP/GLP-1

4.9/5 average rating
Regimen app showing today's schedule

Regimen is the best tirzepatide tracker app for managing your Mounjaro or Zepbound protocol. Tirzepatide's dual GIP/GLP-1 mechanism delivers powerful weight loss results — but tracking your progress through its six-step titration schedule is critical. Regimen's compound database is built on published pharmacokinetic data and FDA prescribing information. Regimen logs every dose, tracks your weight loss at each titration step, monitors side effects, and shows you how tirzepatide is affecting your body composition, appetite, and energy. Free — every feature unlocked for your first medication. No paywall, no trial, no credit card. Rated 4.9 stars on iOS and Android.

Quick answer
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.

Compounded tirzepatide needs precision tracking.

You chose compounded for a reason. Don't wing the dosing:

Calculating draw volume from different compounded concentrations — and the stakes feel high when you're doing the math yourself

Managing titration timing without a provider who automatically ships your next pen strength

Tracking whether your results match what others report at similar doses, or if something's off with your compound

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.

Why tracking tirzepatide matters

Concentration calculator built in

Compounded tirzepatide comes in varying concentrations. Regimen handles the math from your specific vial strength to exact syringe units.

Self-managed titration

Without auto-shipped pens, you're managing your own titration schedule. Regimen tracks your dose history and flags when your next step-up is due.

Dose-response correlation

See exactly how each dose change impacts your weight, appetite, and energy — critical data for optimizing your compounded protocol.

Why people are switching to Regimen

"I was juggling my peptide schedule between a notes app and my calendar, and I was constantly stressed about missing a dose. Regimen fixed all of it. The reminders and calculator are essential."

Alex T., Bio-Optimizer

"I finally feel in control of my weight loss journey. The photo comparison feature is addictive. Seeing my progress next to the tracking data motivates me way more than just the number on the scale."

How we built the tirzepatide tracker

Tirzepatide is the active ingredient in both Mounjaro (branded for type 2 diabetes) and Zepbound (branded for weight loss), and it's also widely dispensed in compounded form by US compounding pharmacies. For most people, the practical complication is supply: you might start on branded Zepbound, switch to compounded during a shortage, swap to Mounjaro because your insurance covers it differently, and end up wanting one continuous history across all of those forms.

Regimen's tirzepatide tracker is built for that reality:

  • Branded dose logger: log Mounjaro and Zepbound by pen strength (2.5, 5, 7.5, 10, 12.5, 15 mg). The app stores the full titration history regardless of which brand you were on at each step.
  • Compounded dose calculator: for compounded tirzepatide, log by mg per dose. The reconstitution calculator handles the math when your compounding pharmacy gives you a vial at a specific concentration: enter the vial size and the units you draw, and the app converts to mg.
  • Switching between forms: when you move from branded to compounded (or back), your dose history stays on one continuous timeline. No need to start a new log.
  • Side-effect tracking across 50+ markers: nausea, vomiting, constipation, diarrhea, sulfur burps, the food-stuck feeling, fatigue, sleep, mood, appetite, energy, plus custom markers.
  • Weight trend overlay: every dose change shows on the same chart as your weight, so you can see how the full titration arc moved your body composition.
  • Lab tracking: HbA1c, fasting glucose, lipid panel, hematocrit. Each lab pull plots on the dose timeline so you can see how labs moved across the dose history regardless of source.
  • Apple Health and Google Health Connect: weight, sleep, resting heart rate, blood pressure auto-sync.
  • Multi-compound support: most tirzepatide users on Regimen also track at least one other compound (TRT, a peptide, HRT, supplements). One app, one timeline.

Frequently Asked Questions

How do I calculate compounded tirzepatide doses in syringe units?

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.

Can Regimen track branded Mounjaro or Zepbound alongside compounded tirzepatide?

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.

Does Regimen handle split-dose or microdose tirzepatide schedules?

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.

Can I log glucose and HbA1c on tirzepatide?

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.

What tirzepatide side effects can I log?

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.

How does Regimen compare to Shotsy, Glapp, or MeAgain for tirzepatide tracking?

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.

Is there a free tirzepatide tracker in Regimen?

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.

Does Regimen treat Mounjaro, Zepbound, and compounded tirzepatide identically?

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 protocols. Your data flows the same way across all three.

Stop guessing. Start optimizing.

Your protocol deserves better than a notes app and a calendar.
