Why this exists.
Peptide buyers face long catalogs, inconsistent product names, scattered testing documents, and community discussion that is hard to evaluate. PepGrades collects the same kinds of public information a careful person could find on their own, then puts it into a consistent structure.
What a grade means.
A grade summarizes the vendor record PepGrades could observe under the current rubric. It is not certification of a vendor, laboratory, product, shipment, or medical outcome. Limited labels show when a material part of the evidence could not be measured.
How commerce is kept separate.
Scoring and shortlist selection do not receive affiliate fields. A commercial relationship is attached only after those decisions are complete. Payment or participation in an affiliate program cannot buy a grade or recommendation.
Current product boundaries.
Vendor destinations use first-party redirects and aggregate outbound-click counts. A commission relationship is disclosed beside each affected link. PepGrades uses no visitor account, advertising network, or third-party analytics tag, and grades and comparisons retain their dated observation labels.
