Vial Longevity & Runway Calculator
Calculate how many days and weeks a reconstituted vial will last based on your dosing protocol and monitor BAC water shelf life limits.
Vial Runway Math & Potency Protection
Written out so you can check it by hand. The app runs this exact function — not a second implementation that drifts.
Vial longevity calculates the runway of a reconstituted vial given your specific dosing schedule.
1. Total Doses per Vial: Total Doses = Total Content (mg) ÷ Dose Amount (mg).
2. Duration in Days: Days Lasting = (Total Doses × 7) ÷ Weekly Dose Count. At 7 doses per week (daily), 20 doses will last 20 days.
3. Bacteriostatic Water Limit: Once reconstituted, 28 days is the recommended maximum duration for multi-dose vials stored at 2–8°C.
The number is right. Now keep the record.
Save doses, set reminders, and keep the math in one place. The calculators stay free either way.
