243 vendors · Updated 17 August 2026

243 research peptide vendors. Here’s what each one will actually show you.

Most won’t show you a lab report. We checked all 243 and recorded what each one makes public, so you can judge for yourself. Nobody can pay to rank higher.

Every listed vendor

Every vendor, in the state we found it

This is not a ranking. We don’t score vendors or tell you who’s best — we show you what each one makes public and let you decide. Filter by how much proof they offer, or by country. Open any vendor to see what we found and when we checked.

243 listed

Where these come from. A Finnrick A–B range is Finnrick’s grade, relayed here — one outside grader’s reading of the batches it happened to test. It is not our rating. Everything else on a row is what the vendor says about itself, repeated here and not checked. Saying more is not the same as being better.

Before you cite a vendor. A listing here is not an endorsement, and a “third-party tested” claim without a published COA is a claim, not evidence. Always verify third-party lab testing before any research use.

How we check

What we look for, and what it proves

The six things we look for

When we check a vendor, we look for six things: a lab report you can open, a claim that they test, the name of their lab, where they ship to, a contact address, and an X account.

Only the first one is proof — it’s a document we can open and read ourselves. The other five are the vendor telling us about themselves.

27 vendors have nothing going for them except a claim that they test, with no report to open.

A note on what we can’t attribute. About 115 lab results we hold aren’t linked to a specific vendor in our records. So “nothing there” means we found nothing we could attribute to them — not that nothing exists.

About letter grades

Some vendors carry a letter grade from Finnrick, an outside grader. 12 do.

But we only hold an independent lab result for 5 vendors — and just 1 vendor is in both groups. A grade is not the same thing as a test someone has actually seen.
