About this app

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.
