Built for tracking tirzepatide for weight loss - log doses, monitor body composition, and see your results at every step.
Free to download. Free for your first compound.
Regimen tracks Zepbound (tirzepatide for weight loss) doses across all six pen strengths (2.5, 5, 7.5, 10, 12.5, 15 mg) with built-in dose scheduling, side-effect tracking across 50+ daily markers, lab integration, progress photos, and Apple Health and Google Health Connect sync. Multi-compound friendly: track Zepbound alongside any other medication, peptide, or supplement in one app. 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.
Zepbound (tirzepatide) is newer, meaning less long-term community data exists. Your own tracked history becomes your most valuable reference.
Same 6-dose tirzepatide schedule as Mounjaro. Regimen tracks it so you step up at the right time, every time.
Zepbound's dual GIP/GLP-1 action can affect body composition differently. Track weight and progress photos together for the full picture.
Same compound. The tracker name does not matter; what matters is logging dose and date consistently. Regimen's Zepbound and Mounjaro trackers use the same underlying tirzepatide tracking. Pick whichever matches your prescription.
Take it within 4 days of the missed dose if possible. If more than 4 days have passed, skip it and resume your normal schedule. Log the miss in Regimen so you can correlate any side-effect rebound with the gap.
FDA labeling calls for 4 weeks per step. Many providers hold longer (6-8 weeks) if side effects are tough or if you are responding well at a lower dose.
Yes, between 36 and 46°F refrigerated. Once you have started a pen, it can stay at room temperature (up to 86°F) for up to 21 days. Log the opening date.
Response varies widely. In Lilly's clinical trials, most participants saw measurable weight loss during the early therapeutic doses, with continued loss over the following months. Track your own weight trend so you can see how you're personally responding, not just what an average curve says.
Select the pen (2.5, 5, 7.5, 10, 12.5, or 15 mg) and confirm the injection. The app stores every titration step with timestamps so each new pen lines up against weight, appetite, and side effects in your timeline.
Yes. Branded Zepbound logs by pen strength. Compounded tirzepatide logs by mg per dose since vial concentrations vary by pharmacy. Switching between them keeps your dose history and weight trend continuous.
Yes. Weight, body fat percentage, BMI, lean mass, and resting heart rate sync via Apple Health or Google Health Connect. The weight trend plots directly under your Zepbound dose timeline so each titration step lines up with what your scale actually did.
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 Zepbound alongside any other compound, models blood levels with published PK data, and includes lab correlation on the free tier.
Yes. Progress photos store with timestamps and dose-step labels so you can scrub through visible changes across each pen. Body fat percentage and lean mass from a smart scale plot on the same chart as weight.
Yes. The free tier covers one compound, including Zepbound, with full dose logging, side effects, weight sync, and lab tracking. Pro ($4.99/month) unlocks multi-compound stacks and the Signals pattern engine.
The underlying compound is identical (tirzepatide), so the math and PK curves match. The Zepbound view emphasizes weight trajectory and body composition; the Mounjaro view surfaces HbA1c and glucose more prominently. Your data flows the same way either side.
Zepbound users who log every injection (not just dose changes) tend to maintain better adherence over time. The act of logging creates a feedback loop that reinforces the routine. Users on auto-reminders log more consistently than users on manual entry.
