The requester ordered HGH from Shijiazhuang Sizi Trading over WhatsApp and received a case of unmarked vials stamped only "F10," with no labels or COA.

A Shijiazhuang, China trading company reached through Alibaba and WhatsApp, shipping research peptides and HGH.

Where it trips our checks

• COA traceability: the vials arrived unmarked except for a factory code, with no COA or paperwork, so contents and dose cannot be verified. Unmarked vials with no COA are a pattern we see repeatedly around bad actors.
• Contact transparency: it's a generic trading-company name that buyers report finding only on shipping labels, with ordering pushed to a WhatsApp number and no verifiable brand.
• Independent feedback: public reports are thin and mixed, one person claims long-time ordering, others are openly skeptical, and no one has confirmed a quality test.

Bottom line: No confirmed scam, and the order did arrive, but unmarked vials, no COA, and a faceless trading-company identity leave contents and dose unverifiable. Provisional; an independent test of the F10 HGH would settle it.
