Peptide Calculator: Vial

Track peptides and GLP-1s. Log doses, calculate dilutions, and track your progress, injection sites and side effects Synced across all your devices privately.

Vial is the calculator and logbook for peptides. Reconstitute a vial once, and100 syringe — shown to scale on a syringe diagram so you can see the fill before you draw it. Save it to the vial so every future entry uses the same math.

ONE-TAP LOGGING Compound, dose, site, and time in two taps — or one with "Repeat yesterday." A body-map site picker highlights your least-recently-used injection site so rotation stays even. Every entry shows a live syringe readout for the units to draw.

SCHEDULE & REMINDERS Build a schedule that matches how you actually dose: daily, weekdays, every-other-day, interval, or on/off cycles. Reminders fire only for entries you scheduled — no streaks, no marketing nudges. Log, snooze, or skip straight from the notification. Vial tracks your adherence so you can see how closely you're keeping to plan.

INVENTORY & COST Track every vial: remaining mg, cost per mg, and days of supply. Vial flags low stock before you run out. Pens, oral, nasal, and topical formats are supported alongside vials. Open any compound to see its half-life and an estimated concentration curve over time.

APPLE HEALTH INSIGHTS Overlay weight, HRV, resting heart rate, blood pressure, and sleep from Apple Health on your dose timeline. Add daily check-ins for energy, mood, sleep quality, and notes, and keep a side-effect log.

PROGRESS PHOTOS Attach an optional photo to any daily check-in and review them all in a date-sorted gallery — your progress over time, kept private on

BLOODWORK Record lab markers with values, units, and reference ranges, and chart any marker over time.
