Peptide testing labs: which ones you can verify

A certificate of analysis is only evidence if a stranger can check it. PepAssure recognizes a lab under one rule: it runs a public certificate lookup that anyone holding a report can use to confirm the document is the lab’s. Below is every lab we recognize, what its lookup accepts, how many results we hold from it, and the labs we have seen in the data but do not recognize — with the reason.

11 recognized labs · 10 with results on file · 2,547 results from recognized labs, 1,681 of them blind-tested · latest result Oct 21, 2026

Recognized labs

How recognized-lab results are weighted

  • Blind-tested (weight 1). Finnrick and Janoshik results we read from the service’s own public index: the vendor did not pick the sample. Finnrick is a blind-buy testing service that routes samples to partner labs it anonymises; its public pages carry grades, not purity percentages, which is why its purity column below is empty.
  • Vendor-submitted (weight 0.5, capped at 85). A certificate from a recognized lab that a vendor uploaded or that we read from a lab’s or catalogue’s index, with the purity figure confirmed from the document. The vendor chose what to send, so it counts for half and a vendor with only this class is capped.
  • Never scored. A vendor’s own published PDF where the lab has no public lookup, and any purity number typed into a form.

Full rules: methodology. Check a certificate you hold: COA checker.

Labs in the data we do not recognize

These names appear on certificates we have indexed. Their results are stored and shown but never score, because we could not find a lookup a stranger can use. A lab that adds one can ask to be reviewed at corrections.

Counts regenerate hourly from PepAssure’s evidence index. “Recognized” means the lab’s reports can be checked by anyone holding one; it is not a statement about a lab’s accreditation or accuracy. Lab names are identifiers, not endorsements.
