## Description

Free peptide dose calculator with vial tracking, injection log and site rotation. No account, no ads, everything stays on your phone.

Peptide Calculator does the dose math so you never second-guess a syringe again. Enter your dose, the amount of peptide in the vial and the water you added, and get the exact volume to draw in mL and syringe units for U-100, U-50 and U-40 syringes.

Then keep going: save the vial, log each dose in one tap, rotate injection sites with a color-coded body map, and get reminded when the next dose is due. Free, no account, and nothing leaves your phone.

DOSE CALCULATOR
- Dose mode: dose in → mL and units out, with a syringe graphic showing exactly where to draw to
- Reconstitution mode: enter the units or concentration you want per dose and get the water volume to add
- mg and mcg, U-100 / U-50 / U-40, quick-pick chips for common vial sizes and water volumes
- Shows concentration (mg/mL) and how many doses a vial will give you
- Copy or share the result as text

VIAL TRACKING
- Save a calculation as a vial with peptide name, strength, water, concentration and reconstitution date
- Doses remaining count down automatically as you log
- Expiry countdown (28 days by default, editable) with a heads-up before a vial runs out or expires

DOSE LOG
- One-tap log from any vial: dose, units, time and injection site pre-filled
- Calendar view with a dot for every logged day, plus a simple weekly summary and streak
- Export your history as PDF or CSV for your own records or your doctor

SITE ROTATION
- Body map with abdomen, thighs, arms and glutes
- Each site is color-coded by days since you last used it, so the next spot is obvious

REMINDERS
- Per-vial schedules: days of the week, every X days or every X hours
- Optional repeat nudges if you miss one
- Mark a dose as taken straight from the notification

BUILT FOR PEOPLE WHO WANT A TOOL, NOT A SUBSCRIPTION
- 100% free, no in-app purchases
- No account, no sign-in, no email
- All data is stored on your device. We don't collect it, we don't see it
- No onboarding quiz, the calculator is the first screen you see

Works with any reconstituted peptide or GLP-1 vial you enter yourself, including BPC-157, TB-500, Ipamorelin, CJC-1295, Semaglutide, Tirzepatide and Retatrutide.
