Zepbound® tracker
Zepbound is tirzepatide dosed for weight management — the medication SURMOUNT-1 made famous. ShotLock pairs its six-step ladder with protection, level curves and the trial benchmark itself.
Schedule & reminders
Once weekly on your schedule. ShotLock's reminders are backed by optional Shot Protection — every non-system third-party app stays blocked from shot time until you log. Travel or a schedule change? Move your shot day and everything follows.
Dose titration, handled
The standard Zepbound® ladder (2.5 mg → 5 mg → 7.5 mg → 10 mg → 12.5 mg → 15 mg) is built in. Set your current step and ShotLock tracks your dose history, reminds you when a step-up is due per your prescriber's plan, and reflects each change in your level curve.
Your estimated level curve
With a ~5-day half-life, tirzepatide gives your week a clear shape: a post-shot rise, a peak around days 1–2, then a steady fade into shot day. ShotLock's estimated curve makes that rhythm visible and explains each phase.
Benchmarked against SURMOUNT-1
Zepbound's doses are what SURMOUNT-1 studied (up to ~21% average body-weight reduction at 72 weeks at 15 mg). ShotLock plots your curve against the trial's, week by week, with full citations in the Research Library.
Dosing information describes the manufacturer's standard schedule for context only. Your prescriber's instructions always take precedence. ShotLock provides no medical advice.
Frequently asked questions
How is Zepbound different from Mounjaro in ShotLock?
Same molecule (tirzepatide), same ladder — choose Zepbound so your log matches your prescription. Levels, phases and benchmarks work identically.
Can I compare my progress with SURMOUNT-1 at my dose?
ShotLock benchmarks against the published trial trajectory and labels what the endpoint reflects. Individual dosing paths vary; the comparison is context, not a target — and every figure is cited.
Does ShotLock track my Zepbound pen supply?
Yes — log your pens and ShotLock counts down with each shot, warning before you run out or a pen expires.
