Evidence and attribution
Material claims require a source and observation or verification date. We distinguish independently verified information, attributable supplier claims and unverified information. External review scores retain their source and count and are never presented as our editorial score.
Scoring and selection
Scoring follows the public methodology. Selection for evaluation is not endorsement. Missing evidence lowers confidence and may affect the relevant category only under the published rubric; it is never silently converted into proof of failure.
Commercial independence
Suppliers cannot pay for placement, a guaranteed score, favourable copy or removal of substantiated criticism. Affiliate status is recorded in the data layer and disclosed before eligible links.
Safety and scope
Coverage is confined to supplier websites, evidence, transparency and legitimate research procurement. We do not provide dosing, administration, treatment, weight-loss, bodybuilding, anti-ageing or disease claims.
Updates, corrections and replies
We conduct scheduled and event-driven reviews. Material edits are logged. Anyone may submit a correction with evidence; suppliers have a right of reply but no right to dictate the conclusion. See corrections and appeals.
Authors and conflicts
Named authors and reviewers must disclose relevant commercial or personal conflicts. Credentials are published only after verification.
