The Problem

PepVault is a free mobile and desktop application that records peptide injection data, vial inventory, schedules, injection sites, body measurements and side effects, and can export the log as a CSV file. Users start by entering each vial’s label information—strength, lot number, expiration date, storage condition and whether it is sealed or reconstituted. The app computes the remaining volume based on doses logged. A schedule module lets the user define dosing intervals and activates local push notifications when a dose is due. When logging a dose the user selects the peptide, enters the amount, taps a body‑map to mark the injection site, adds optional notes and the entry is timestamped and stored locally. All records are kept on the device; no cloud sync is required. The built‑in calculators perform reconstitution math, unit conversion, vial‑duration estimates and water‑volume calculations entirely in‑browser without sign‑up. Export functionality writes the complete history, including measurements and side‑effect entries, to a CSV file that can be opened in spreadsheet software.
