Peptide Vendor Reviews — Scored & Fact-Checked

How our reviews are made
Scores are entered personally by the named editor — never machine-generated — following the published criteria in our review process. We weight COA transparency heavily because published third-party testing is the clearest quality signal in this market. Reader ratings are collected separately, moderated, and shown alongside (never merged with) the editorial score, and every reviewed vendor has a standing right of reply via the official response section.
Review FAQs
Do vendors pay for reviews or scores?
No. We accept no payment for ratings, placements, or edits. Affiliate commissions, where they exist, are disclosed on every page and never influence scoring.
What does the COA score mean?
It rates whether a vendor publishes independent Certificates of Analysis, how easy they are to find, and how recent they are — the strongest available signal of product quality.
Can a vendor respond to a review?
Yes. Every review includes an official vendor-response section, published unedited. Factual corrections with evidence trigger a re-verification, logged in the changelog.
