Terms of use

By Jamie, Editor · The Peptide Watch · updated 29 September 2026

The Peptide Watch is an independent record of what UK research-peptide sellers publish about their testing. Using the site means accepting what follows.

What this site is

It records whether a seller publishes a certificate of analysis that can be verified in its own name, and what else it publishes. It sells nothing, takes no payment from any seller and links to none of them.

What it is not

It is information, not advice. Nothing here is medical, legal, dosing or purchasing advice, and nothing here is a recommendation to buy from anyone. The products described are sold for research use. Some compounds covered here are medicines, and the page for each one says so.

How far you can rely on it

Each page records what we read on the date shown. Sellers change their sites, and a page can fall out of date between checks. A certificate shows that one sample was tested once. It does not show what is in any other vial. We take care to be accurate, and we cannot promise that every page is complete or current.

Corrections

If something is wrong, tell us. We check it against the public record and correct the page where the correction holds. Sellers are welcome to ask. Our editorial standards set out the test every seller is judged by.

Using what we publish

The open dataset is free to use with credit to The Peptide Watch, under the Creative Commons Attribution 4.0 licence. You may quote our pages with credit. The "Verified" badge may be shown only by a seller we list as verified, and only while it is listed.

Your rights

Nothing in these terms takes away any right you have under UK law. How we handle data is set out on the privacy page.
