The room’s verification standard and the log that records it. What counts: an independent third-party report on a lot you personally bought, from a lab the room recognises, with the lot number legible. What does not: a supplier-issued COA on its own, a screenshot, a referral link, or a friend who says it was fine.

WHAT COUNTS AS EVIDENCE: an independent report, on a lot you bought yourself, with the lot number, from Janoshik / Medutest / PeptideMeter, submitted blinded where possible. WHAT DOES NOT: the supplier’s own COA alone, a screenshot, a referral link, a friend’s word.
Verification is revoked on a confirmed failure and the revocation stays in the log permanently. Nothing is deleted, including our own mistakes.
Verification has never been for sale and never will be. Offers get posted publicly with the sender redacted.
