Track your GLP-1 and peptide research without spreadsheets, scattered notes, or another monthly subscription. Peptide Ledger brings protocols, dose history, vial inventory, reminders, progress, labs, observations, and research context together in one private ledger. EVERYTHING IN ONE PLACE • Create and track custom protocols • Log doses, observations, check-ins, and milestones • Track open and sealed vials, lots, concentration, cost, and expiration • See projected runout and reorder timing • Review doses, protocol changes, inventory events, progress, and labs in Timeline • Import body weight from Apple Health when enabled • Use reminders, widgets, and supported Siri actions RECONSTITUTION TOOLS Use your own entered values to calculate concentration, draw volume, and vial-mix references with a clear Reconstitution Solver. The app does not recommend doses or mixing amounts. PRIVATE BY DESIGN • No account required • Data stored locally by default • Optional private iCloud backup and sync • Face ID, Touch ID, or passcode App Lock • No advertising trackers START FREE Explore the Research Library, Now view, reminders, Reconstitution Solver, and core tracking tools before deciding whether you need Pro.
