# The Peptide Index

> Data as of 2026-09-25. Prices are refreshed nightly. Each vendor public-record signal carries the date it was last checked: most are re-checked daily or weekly; FDA warning letters are matched nightly against the FDA warning-letter list; trademark, business-registry, BBB and non-FDA enforcement records (court cases, other agencies) only when reviewed by hand.

> The Peptide Index (PeptidePriceHistory.com) is an independent transparency index for the research-peptide market: it normalizes publicly listed vendor prices to a single $/mg figure, tracks the full nightly price history, and ties each vendor storefront back to the public record (legal entity, domain age, trademark ownership, BBB listing, and any FDA warning-letter or enforcement references).

Every published fact links back to its primary source. Each vendor profile carries a "Verify" link from its resolved legal entity, trademark owner, domain-age, BBB listing, and any FDA warning-letter or enforcement reference straight to the underlying public record -- so any claim here can be checked, and cited, at its source rather than taken on trust.

A vendor cannot buy a trust tier, a price, or a position in a price-sorted table -- those are computed identically for every vendor and are never for sale. Prices are publicly listed vendor prices, ex-shipping, normalized to $/mg and refreshed nightly. A vendor "trust tier" is a public-record transparency signal only -- not an endorsement, safety verdict, or accusation. All data is preliminary, not independently verified, for research use only, and is not medical advice.

## Key sections
