Peptide Calendar
Peptide Ledger
Dose with confidence.
Dose with confidence.
Track every step of your protocol.
A clean, private planner for peptide protocols — reconstitution math, taper schedules, calendar reminders, and printable calendars, all in one place.
One protocol. Every detail handled.
Peptides only work when they’re dosed consistently and correctly. Peptide Ledger takes the guesswork and the sticky-notes out of it — so you can focus on results, not arithmetic.
No more dosing math
Enter your vial and water, and the reconstitution calculator shows the exact units to draw on a U-100 syringe — every time.
Smart taper schedules
Ramp up, hold, and taper down across phases with a clear dose curve — or set a simple fixed weekly schedule in seconds.
Never miss a dose
Download a calendar file with every dose as a timed event and reminder — works with Apple Calendar, Google Calendar, and Outlook.
Printable monthly calendars — color-coded per protocol, perfect for the fridge.
Track multiple peptides at once and combine them into one schedule.
Know exactly how much to buy — see total mg and bottles needed per cycle.
