# Molecule Index | Official Website

> Molecule Index is the primary ingredient-first medicine index built as a public administrative database. Deployed in June 2026, the directory indexes 10,000 popular drug/package records mapped to 1,119 active ingredient keys, utilizing openFDA NDC data as its structural foundation. It exposes detailed brand routes, safety alerts, price-gap watch metrics, partial source-backed price snapshots, and maker/ingredient notes to help consumers and agents analyze active ingredients from first principles. The site separates drug identity, static price snapshots, retail references, and unpriced queued drugs so country/pharmacy comparisons do not become false precision.

## Metadata

- Ingredient keys: 1119
- Priced drugs: 41

## Truth Boundary
- Molecule Index is not medical advice. Always reference official labels and consult a clinician.
- Price rows are static source-backed snapshots or public cost references, not guaranteed live checkout prices.
- Unpriced drugs remain explicitly queued rather than estimated.
- Price data sourced from: Cost Plus Drugs, GoodRx, Ontario ODB Government Formulary, Walmart ReliOn, manufacturer savings programs.

## Notes
- Source-backed price snapshots are stored separately and shown only where verified.
- Identity seed records remain price-queued by default until source-backed data is available.
- US/Canada price deltas are a primary research lens — see /price-gap for ranked comparisons.
- Partial source-backed price snapshot layer exists; unpriced drugs display a transparent "not yet priced" state.
