OnePin TRT & Peptide Tracker

OnePin is the protocol tracker built for people who run real peptide and supplement protocols — not a glorified pill reminder. WHAT IT DOES • Track every peptide, supplement, and dose across complex multi-phase protocols • Smart syringe grouping with built-in compatibility checks (safe lists, avoid lists, contamination warnings) • Phase-aware dose calculations that handle taper, escalation, and break cycles automatically • Vial life math, doses-per-vial, supply forecasting per cycle • Day-by-day calendar with cycle countdowns and rest-day awareness • Inventory tracking with batch dates, costs, and phase-aware capacity projections • Injection site heat-map rotation so you never overuse a site • Protocol templates for popular compounds with editable starting points • Dose log audit trail and protocol compliance dashboard • Compound database covering peptides, supplements, blends, and bioregulators • Household sharing — track for yourself plus a partner from one app CYCLE TYPES SUPPORTED • Indefinite (daily / EOD / weekly / specific days) • Yearly Schedule (auto-spaced cycles per year) • Fixed Count (run N cycles then stop, with end-date preview) • Custom phases with per-slot dose escalation INTERACTION SAFETY • 200+ compound database with curated safe/avoid pair data • Real-time syringe planner that flags reactive compounds and isolates them per chemistry safety rules • Same-day dosing interaction warnings across routes WHO IT'S FOR If you're running anything more complex than "one compound, daily, forever," you know the pain of spreadsheet-tracking peptide protocols. OnePin replaces that spreadsheet. Designed for: research peptide users, supplement biohackers, protocol designers, household partners managing each other's protocols, anyone running multi-phase or cycle-based regimens. IMPORTANT NOTICE OnePin is an education and tracking tool. It does not provide medical advice. Consult a physician before using any compound. The app does not validate the safety or legality of any compound or protocol you enter. PRIVACY Your data stays yours. Local-first storage with optional cloud sync via your account.
