Peptide Vault is the tracking and research companion for people who take their protocol seriously. TRACK, FREE Track an FDA-approved GLP-1 (semaglutide, tirzepatide, and other approved GLP-1s) at no cost: dose schedule, next-dose countdown, streaks, adherence, dose history, and reminders. The Reconstitution calculator is free for everyone — vial size and water in, syringe units out. BUILT AROUND YOUR SCHEDULE Pick your first dose day and your schedule patterns from it — weekly, twice weekly, three times weekly, every other day, or every two weeks. Log a dose in seconds. Your history lives on a calendar you can actually read. PEPTIDE VAULT PRO • My cabinet — save vial photos, ingredient amounts, concentrations, mix dates and notes, with cabinet backup and restore. • Custom blend protocols — one schedule and one log for a multi-ingredient vial, with a recorded ingredient breakdown. • Coach — a research assistant grounded in your own protocol. Ask about the published research behind the compounds you track. Coach's answers are grounded in published research, and it never gives dosing or medical advice. • Track unlimited compounds across your whole protocol. • Open all 203 compounds in the research library — every entry referenced, with regulatory status, mechanisms, risks and side effects stated plainly. • Site rotation, suggested at every dose. • Dose history and trends across everything you run. • Journal with full record export, any time. YOUR DATA No account required. Your protocol, logs, and journal live on your device. Coach shares only what you approve — your compound names and stack summary, never your journal, notes, or Apple Health data. Peptide Vault is a tracking and reference tool. It does not provide medical advice, diagnosis, or treatment. Always consult a medical professional before using peptides.
