How scoring works

Showing 3 reviewed vendors

Detailed criteria and source records remain inside each evidence review.

The directory standard

Answers first. Evidence underneath.

Every published profile shows criterion-level findings, source provenance, evidence dates, limitations, conflicts, and score coverage. “Not verified” remains visible and is never quietly replaced with a favorable assumption.

What each profile investigates

Objective dimensions, with unknowns left intact.

A composite percentage is never shown without the number of criteria that were actually scored.

Dimension 01

Lab and report verification

Can the laboratory and document be independently connected to the represented report?

Dimension 02

Batch traceability

Does the report identify a batch or lot that can be matched to the vendor claim?

Dimension 03

Testing scope

Which separate tests address identity, purity, quantity, sterility, and endotoxin?

Dimension 04

Evidence provenance

Did the evidence come from the vendor, a third-party laboratory, or PeptidesReview independently?
