Know when you'll run out — before you do
Running dry mid-week is how doses get missed. ShotLock's Medication supply screen counts down your inventory with every logged shot — in Quick mode for simple pen tracking, or Titration Plan for dose ladders and vial workflows.
Quick mode for simple inventory
Pre-count your doses at a fixed mg amount — one pen, a stack of vials, whatever's in the fridge. Each logged shot decrements automatically and shows your projected run-out date. No spreadsheet required.
Titration Plan for real workflows
Map your dose ladder step by step, track vial inventory with concentration and beyond-use dates, and let ShotLock plan draws from the top vial in your stack. Built for compounded semaglutide and tirzepatide workflows.
Weekly runway and refill reminders
Premium Titration Plan projects a week-by-week runway — dose, date, shots remaining, and vial depletion markers — so you can see exactly when you'll need a refill. Set a reminder days before projected run-out and start the pharmacy dance with time to spare.
Frequently asked questions
What's the difference between Quick and Titration Plan?
Quick mode tracks a fixed dose amount and counts down pre-loaded doses — ideal for a single pen strength. Titration Plan handles multi-step dose schedules, vial inventory, draw planning, and the full weekly runway projection.
Does supply update when I log a shot?
Yes — every logged injection automatically decrements your inventory. No second step, no manual stock-keeping.
Is the weekly runway a Premium feature?
Basic dose inventory and vial tracking are free. Premium unlocks the multi-step Titration Plan runway projection and refill reminders tied to your projected run-out date.
