How a review gets written

Sources

• Lab tests. Independent lab results for identity, purity and fill, mostly vials sent in anonymously by members of the public. We grade the measurements ourselves, and each result links to its original lab report. Reports a shop publishes itself count at half weight.
• Third-party ratings. Only attributable, non-generated rating records may be shown, with source links and limitations. Customer review titles, bodies and efficacy anecdotes are not republished. Synthetic review generation and publication have been retired.
• Storefront checks. Whether the vendor's site loads and still lists products, with the date we last checked.

Who writes the verdicts

Reviews are written by the Peptide Vendor Reviews editorial team and bylined to the team. The grade itself is arithmetic: it follows the published rubric and nobody can change it by hand. The written verdict explains what the grade means for that shop.

We do not provide medical advice, compound-benefit claims, dosing, administration instructions or human-use recommendations. Listings do not establish product safety, suitability, approval or legal status.

Money

Some outbound links may earn a commission. That never changes a grade, the order of a lab-score ranking, or whether a failed test is shown. Vendors cannot pay to be reviewed, removed or re-graded. When a review shows an alternative shop for a peptide, the shop must first pass a fixed quality bar. Affiliate status and partnership terms do not affect the selection or ordering of alternatives. Partner links are labelled.

Corrections and vendor replies

If a number is wrong, email corrections@peptidevendorreviews.org with the certificate or batch number. Confirmed errors are fixed and the review shows an updated date. Vendors can send newer certificates; they are added once the lab confirms them, and older results stay visible.
