The transparency index for peptide vendors.
The peptide industry runs on anonymity. We tie storefronts back to the public record and price every vendor nightly — so you decide with facts, not hype.
No affiliate links, no paid placement. Prices are publicly listed vendor prices, ex-shipping, normalized to $/mg and updated nightly.

Vendors with the strongest public record
Our Verified vendors — storefronts tied to a real, named operator — first, then the strongest Established ones. Each card shows its own tier. A tier is a transparency signal, not an endorsement.

How a vendor earns a tier
Every tier is built from primary public records — each signal linked back to its source, so you can check our work.
Legal entity & filings
We match each storefront to a registered business — LLC/Inc filings, trademark ownership, agent of record — and link the record.
Domain & TLS footprint
Registration age, hosting, and certificate history separate an established operation from a week-old shell.
Enforcement screen
We screen for FDA warning letters and agency actions, attributed to the source as a matter of public record.
Ownership signals
Shared operators, addresses, and networks surface who is really behind a cluster of storefronts.
