PeptideCalc
Enter your dose, what's in the vial and the water you added — get the exact volume in mL and the units to draw on a U-100, U-50 or U-40 syringe. Then save the vial, log each dose, rotate sites, and get reminded when the next one is due.
Everything stays on your iPhone. No account, no servers, no tracking, no ads — and no in-app purchases.
What it does
- Dose calculator — mL and syringe units, with a syringe graphic showing where to draw to. Works in mg or mcg.
- Reconstitution mode — tell it the units or concentration you want per dose, and it gives you the water volume to add.
- Vial tracking — concentration, doses remaining and an expiry countdown for every vial you save.
- Dose log — one-tap logging, a calendar view, and PDF or CSV export for your own records or your doctor.
- Site rotation — a body map colour-coded by how long it's been since you used each site.
- Reminders — per-vial schedules by weekday, every X days, or every X hours, with a Log dose button on the notification.
Not medical advice
PeptideCalc is a calculator and a personal log. It performs arithmetic on numbers you enter and records what you choose to log. It does not recommend doses, schedules, protocols or products. Always follow the guidance of a licensed healthcare provider, and double-check every calculation before injecting.
