Vanguard Laboratory vs Gold Standard Analytics
Vanguard Laboratory in Olympia, Washington is one of the few peptide-testing labs holding ISO/IEC 17025:2017 accreditation, with a branded "Verified by Vanguard" lookup and published per-test prices. Gold Standard Analytics is not accredited and says so. Where the two differ is method transparency, what is published, chain of custody, ordering and price for a full identity-purity-content panel.
