Claimed, unverifiedPurity
Vendor links a named-lab report on the product page, but PeptideCompare directly confirmed that this vendor's AOD-9604 listing links a Janoshik report belonging to a different company (Client: Telegram @tracyfromqsc, Manufacturer: QSC) — not PeptidesDirect. Given confirmed misattribution on at least one listing, no lab link from this vendor is trusted until its Client field is individually checked to show PeptidesDirect itself
