Mounjaro® tracker
Mounjaro (tirzepatide) is a once-weekly dual GIP/GLP-1 injection with a six-step ladder to 15 mg. ShotLock tracks every step, models your level curve, and keeps shot day from slipping.
Schedule & reminders
Once weekly, any time of day. ShotLock reminds you on your day, and Shot Protection blocks every non-system third-party app until you log — the difference between intending to take your shot and having taken it.
Dose titration, handled
The standard Mounjaro® 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
Tirzepatide's half-life is about 5 days, so the weekly cycle is a touch more pronounced than semaglutide's. ShotLock's curve shows your estimated build-up at each dose step and the weekly peak-and-trough rhythm, with phase explanations along the way.
Benchmarked against SURMOUNT-1
ShotLock benchmarks your progress against the published SURMOUNT-1 trial (tirzepatide, up to ~21% average body-weight reduction at 72 weeks at the highest dose), week by week and fully cited. Mounjaro is dosed for type 2 diabetes; the trial context is informational.
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
Does ShotLock support all six Mounjaro doses?
Yes — 2.5, 5, 7.5, 10, 12.5 and 15 mg. Set your current step, and your dose history and level curve track every change.
What if I miss a Mounjaro dose?
Label guidance: take it within 4 days, otherwise skip and resume — and confirm with your prescriber. ShotLock reflects the actual timing in your curve, and protection makes the miss much less likely next week.
Mounjaro vs Zepbound — same tracking?
Both are tirzepatide with the same ladder; pick the right brand in ShotLock so your records match your prescription. Tracking and modeling are equivalent.
