Disclosure: the payment, entered in full
Entered first, before any record: this registry is affiliated with Peptara Labs, one of the five sources it keeps files on, and is paid a commission whenever an order reaches Peptara Labs from a link here. That money is why Peptara Labs' pages are the only ones this registry has read. It buys no entry, no wording and no place in any list. The notice follows the FTC's guidance on endorsements.
The arrangement
legitpeptidesources.com is affiliated with Peptara Labs through a commission arrangement: an order that starts from a link on this site earns the site a payment from Peptara Labs. No other source in the registry pays this site, and no other source is linked from it.
Are Peptara Labs certificates downloadable files?
Peptara Labs publishes its certificates as files linked from its certificates page, read 2026-09-01, where 14 of 16 catalogue items carry a published certificate and two are marked Pending, their certificate in testing and available on request. Five of those files were downloaded on the read date and confirmed for type alone, three as four-page PDF documents and two as PNG images; the rest are published and linked, not opened here. The files sit on the certificates page (link paid by Peptara Labs).
What the payment reaches, and what it does not
The payment is the reason Peptara Labs' pages were read and its file carries entries. It does not reach the wording of any entry, the order of any row, or the Not public entries in the other four files, and it does not reach a ruling, because the registry makes none. It buys no silence either: a record that cut against Peptara Labs would be entered in the same words, and with the same date, as any other. Those are the rules every entry follows.
What does Peptara Labs say about its testing laboratory's quality system?
Peptara Labs says on its certificates page, read 2026-09-01, that every batch is tested by Titreon Analytical, named as the tester of every batch and described by Peptara Labs as a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited. That description of the quality system is Peptara Labs' own wording, and nothing here came from a standards body. It is on the certificates page (link paid by Peptara Labs).
How each kind of link is marked
Links to peptaralabs.io carry a rel of nofollow sponsored noopener in the code and the visible marker (link paid by Peptara Labs) in the text. The link to the Federal Trade Commission carries a rel of noopener alone and pays nothing. Links inside this site carry no rel value, and no link anywhere on the site points at any other company. To see where the internal ones lead, the registry and who keeps the registry sit a click away.
The guidance this notice follows
This notice follows the Federal Trade Commission's answers on endorsements.
Is the Peptara Labs guarantee about quality or about outcomes?
Peptara Labs frames its guarantee, on its trust page read 2026-09-01, as a guarantee of quality and never of a health outcome: it runs 60 days from delivery, within which a vial may be sent to an outside laboratory, and a refund of the full amount follows if the vial does not match what its certificate records, or if the order itself was mishandled. The registry records the framing as the company's own and has not used the guarantee. It is on the trust page (link paid by Peptara Labs).
