OnePin is the protocol tracker built for people who actually run peptides and supplements - 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 (avoid lists, safe 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, vial-tracking, and phase-aware capacity projections - Body map injection site tracker with heat-map awareness so you rotate sites - Protocol templates for popular compounds, with editable starting points - Compliance dashboard, dose history, and dose-log audit trail - 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, e.g. 3x/yr bioregulators) - 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 avoid / safe pair data - Real-time syringe planner that flags REACTIVE compounds (GHK-Cu, glutathione, SS-31, LL-37, etc.) and isolates them per chemistry safety rules - Same-day dosing interaction warnings across routes - Bioregulator-specific grouping logic WHO IT'S FOR If you're running anything more complex than "1 peptide, daily, forever", you've felt 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. NOT INTENDED FOR OnePin is a tracking and education tool. It does not provide medical advice. Compounds tracked are sourced as research chemicals or supplements; verify dosing with a physician before use. The app does not validate the safety or legality of any compound or protocol you enter.
