The Peptide Directory

Ownership & Affiliate Disclosure

Last updated October 19, 2026

Ownership

The Peptide Directory's owners also own and operate research-peptide businesses, including vendors listed in this directory. Those vendors are listed with the same fields and the same checks as every other vendor, and we do not score vendors. The default directory order spreads out vendors with related ownership or shared suppliers, as described in our methodology.

How vendors are listed

The vendor directory's default order starts from published criteria (transparency, then core compounds in stock, then typical price per mg); editors also adjust placement to spread out vendors with related ownership or shared suppliers, including businesses connected to our owners, so no group clusters together. Use the sort controls to see a strict criteria ranking (see methodology); other tables are alphabetical or sorted by a published number such as price per mg. Placement is not for sale, and we publish no star ratings, scores or reviews.

Affiliate commissions

We have no affiliate commission arrangements at present. Where a commercial relationship exists, the outbound link carries rel="sponsored" markup. If we add affiliate links, this page will say so.

Facts, not endorsements

Every vendor fact is copied from a public page and shown with its link and the date we read it. A listing is not an endorsement or a quality claim.

What the owners' businesses do not influence

No vendor, including any business connected to our owners, can see or change a page before it is published, choose its position in a table, or remove a sourced fact. Vendor facts use the same fields and the same check process for every listing, and lists sort alphabetically, by a published number such as price per mg, or by the published directory rule; the same code orders every vendor. We do not publish scores, star ratings, "best vendor" picks or Review markup.

How to tell a commercial link

Outbound links to vendors carry rel="nofollow noopener" in the page code; a link covered by an affiliate commission would carry rel="sponsored", and there are none at present. Links to FDA, PubMed, ClinicalTrials.gov, DailyMed and state boards are plain references.
