Methodology
Every supplier is scored on the same seven dimensions, and the overall score is calculated from those dimensions — it is never assigned by hand. Where a supplier has not published something, we record it as not confirmed: an information gap is excluded from the calculation rather than scored as a zero, and we never infer a capability a company has not stated.
House weighting: testing and transparency carry the most weight for research buyers.
Each supplier is assessed against a published set of criteria covering business transparency, testing and documentation, wholesale capabilities, manufacturing capabilities, website experience, commercial purchasing and fulfillment. Assessments use publicly available information: the company's own website, published documentation, and publicly stated programs. Where something cannot be confirmed, it is shown as not confirmed rather than counted against the supplier.
Suppliers can purchase sponsored visibility, such as a featured placement on a comparison page or a sponsored position on a comparison page. Those placements are always clearly labelled as sponsored. Payment does not create, change or influence a Peptide Ad Lab editorial score. Where a comparison page includes a sponsored position, it carries a visible "Sponsored placement" label, and every other position on the page follows editorial score order.
