Disclosure: the payment, entered in full

What's the arrangement?

We're affiliated with Peptara Labs. If an order starts from a link on this site, Peptara Labs pays us a commission. No other source in the registry pays us, and we link to no other source.

Links to Peptara Labs are affiliate links, and we may earn a commission when you buy through them.

Are Peptara Labs certificates downloadable files?

Yes. They're files linked from its certificates page (read 2026-09-01), with two of 16 catalogue items marked Pending, in testing. We downloaded five on that date and checked their type only: three four-page PDFs and two PNG images. The rest we list as published and linked. See the certificates page.

What does the payment change?

It's why we read Peptara Labs' pages and why its file has entries. It doesn't touch the wording of any entry, the row order or the Not public entries in the other four files. It doesn't buy a ruling, because we make none.

It buys no silence either: a record against Peptara Labs would be entered in the same words and with the same date as any other. See the rules every entry follows.

What does Peptara Labs say about its testing laboratory's quality system?

Its certificates page (read 2026-09-01) names Titreon Analytical as its tester, described by Peptara Labs as a third-party laboratory whose quality system is aligned to ISO/IEC 17025:2017, not itself accredited. That's Peptara Labs' wording, not a standards body's. See the certificates page.

How are links marked?

Links to peptaralabs.io carry rel nofollow sponsored noopener in the code, and every page footer names them as affiliate links in one sentence. The Federal Trade Commission link carries noopener alone and pays nothing. Internal links carry no rel, and nothing links to any other company. Internal links lead to the registry and who keeps the registry.

What guidance do we follow?

We follow the Federal Trade Commission's answers on endorsements.

Is the Peptara Labs guarantee about quality or about outcomes?

Quality, never health outcomes, per its trust page (read 2026-09-01). It runs 60 days from delivery. In that window you can send a vial to an outside laboratory, and you get a full refund if it doesn't match its certificate or the order was mishandled. We record the framing as the company's own and haven't used it. See the trust page.
