Whether you research one peptide or a full stack, Peptide Library keeps your schedules, log history and inventory organized, on your device first. WHY PEPTIDE LIBRARY? ◉ TRACKER AND LIBRARY TOGETHER: read about a peptide, then add it to your schedule and inventory in a couple of taps. ◉ INVENTORY THAT KEEPS UP: every entry you log updates what's left in your vials, capsules and sprays. ◉ BUILT FOR STACKS: several peptides, several forms, each on its own schedule. ◉ PRIVATE BY DEFAULT: works offline, with optional account sync and backup. PEPTIDE TRACKER • Schedules: daily, every other day, chosen weekdays, or cycles with on and off weeks. • Reminders for every scheduled entry, with one tap to log or skip. • Log entries with time, amount and notes; log several at once and undo a log. • Calendar: month and week views of what you logged, missed or skipped. • Separate schedules for each form of a peptide: vial, capsules or nasal spray. • Site rotation on a body map, with a suggested next site. • Research Streak: counts the scheduled days you complete and earns XP.
