Peptide Library is the peptide tracker and peptide research library in one app. Plan your peptide schedule, get reminders, log every entry, keep your vial inventory up to date and look up any peptide, all in one place. 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. PEPTIDE STACKS AND BLENDS • Track a whole stack, each peptide on its own schedule. • Save blends and log them together. PEPTIDE INVENTORY • Track every vial, capsule, nasal spray and ready-to-use container. • See what's left, estimated uses left, run-out and reorder-by dates. • Low-stock, reorder and expiry alerts. • Save the price, purchase and opened dates, vendor and COA for each container. JOURNAL, PROGRESS AND BODY METRICS • Journal: daily check-ins for mood, energy, sleep and symptoms, with trends and PDF or CSV export. • Progress photos with a guided camera, timeline and side-by-side compare. • Weight, body fat, lean mass and body measurements, with goals and trend charts. • Works with Apple Health: bring in your weight and body fat (optional, read only). PEPTIDE RESEARCH LIBRARY • Peptide profiles with mechanisms, research summaries, half-lives and PubMed references. • Compare peptides side by side and share the comparison. • Peptide School: courses, guides and FAQs. PEPTIDE TRENDS AND COMMUNITY • Peptide Trends: see what the community is researching and popular schedules. • Community Q&A with other researchers. • Compare vendor listings and prices per mg, with vendors that ship to you listed first, and read supplier reviews.
