Reconstitution maths done right: enter the vial, BAC water and amount, get the syringe units. Plus a dose log, reminders and a 70-compound research encyclopedia.
The peptide tracker that does the math for you. Reconstitution, dose and
syringe units - calculated instantly, then tracked across your whole cycle.
No account. No spreadsheet. Everything on your device.
THE PEPTIDE CALCULATOR
Enter your vial size, your bacteriostatic water and your target dose. See
exactly how many units to draw on an insulin syringe - instantly, every time.
No more redoing the arithmetic three times to be sure.
• Works with 0.3 mL, 0.5 mL and 1 mL syringes
• Warns you when a draw won't fit and suggests what to change
• Live syringe diagram so you can see the amount, not just read it
TRACK EVERY DOSE
Your whole stack on one screen. Each vial shows what's due today, how much
liquid is left, and when it expires.
• Live vial levels that drop as you log
• Expiry tracking from the day you reconstitute
• Low-supply alerts before you run out mid-cycle
• Reminders that follow your real schedule - daily, weekly, every few days,
or custom
NEVER REPEAT A SITE
An interactive body map remembers where you injected and tells you where to
go next, colour-coded by how recently each site was used.
SEE WHAT'S ACTUALLY WORKING
• Weight tracking, with optional Apple Health sync
• Progress photos with side-by-side comparison
• Side-effect logging tied to the specific compound that preceded it
• Adherence and streaks based on your real schedule, not calendar days
70 COMPOUNDS, PROPERLY REFERENCED
Dosing ranges, half-life, storage, reconstitution guidance and what published
studies actually found — for 70 compounds including BPC-157, TB-500,
retatrutide, semaglutide, tirzepatide, ipamorelin, CJC-1295, GHK-Cu and more.
ASK ANYTHING
A built-in assistant answers peptide questions in plain English, grounded in
published literature. It won't tell you what to take — it explains what the
research says so you can have a better conversation with your clinician.
YOUR DATA STAYS YOURS
No account. No sign-up. Everything is stored on your device, with optional
iCloud sync across your own devices. Export everything to CSV whenever you
want.
