PEPTIDE & TRT USERS
Pin reconstitution math once per vial, then pin doses in two taps. Half-life math handles BPC-157, TB-500, ipamorelin, semaglutide, tirzepatide, retatrutide, testosterone cypionate, enanthate — anything with a documented half-life.
DOCTOR-READY
Export a PDF of your logbook for any appointment. Shows medication, dose, time, site, notes. Renders cleanly on any device.
PRIVACY DEFAULT
We don't track you. We don't sell your data. We don't have a server you sign into. Your logbook is on your phone, optionally synced to your iCloud — that's it.
NOT MEDICAL ADVICE
Pinwell is an educational reference and logbook. It does not diagnose, treat, or recommend doses. Every calculation cites its source (FDA prescribing information or NIH databases) — open Settings → Sources & references to see them all. Always consult your prescriber before starting, stopping, or changing any medication and before making any medical decisions based on data shown in this app.
Pinwell. Pin every dose. Log it well.
