Claimed, unverifiedPurity
Vendor advertises 49 published Janoshik COAs, but on inspection the specific Janoshik-tested lot is often a different size than the cheapest/tracked listing (confirmed for BPC-157: only the 20mg lot is Janoshik-verified) — treating as unconfirmed for the specific size/price tracked here
PeptidesDirectIntegrity issue
size varies (5–50mg)€44.99—
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
