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

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.
