Buyers including this requester say Zhang delivers and reships for free, but there is no company, website or verifiable identity behind a single WhatsApp number.

An individual seller reached only through WhatsApp on a Chinese mobile, with no storefront or brand.

Where it trips our checks

• Contact transparency: the only identity is a first name and a WhatsApp number, with no company, address or website to hold accountable. An anonymous seller with nothing to trace is a pattern we see repeatedly around bad actors.
• COA traceability: by the requester's own account, the few third-party lab reports he has sent cannot be tied to the batch a buyer receives.
• Purchase protection: ordering runs over WhatsApp with no checkout or dispute path, and the free reship offer is his own promise.

Not seen: any independent buyer report. Public Reddit and forum sources are empty on this seller, so every positive account traces back to the requester's own referral circle.

Bottom line: No scam pattern found and deliveries are landing, but with an unverifiable identity and no independent evidence this stays provisional. An independent batch test or first-hand reports from outside the requester's network would change it.
