This requester paid HTRA, was handed off to a different WhatsApp number to actually buy, and then received a shipment with no paperwork of any kind.

A generic research-chemical site (htraresearch.cn) run from Yiwu, China, selling GLP-1 peptides over WhatsApp.

Where it trips our checks

• COA traceability: the shipment arrived with no COA or paperwork at all, so nothing ties the vials to a batch or a lab. A vendor shipping with no COA whatsoever is a pattern we see repeatedly around bad actors.
• Contact transparency: the site lists only a free gmail and a Hong Kong WhatsApp, and on contact it redirected the buyer to a different "sales team" number.
• Domain and pressure pattern: the site is a fresh 2025 template with generic boilerplate and, per the requester, a generic price list.
• Irreversible payment: ordering runs entirely over WhatsApp with no checkout or dispute path.

Bottom line: No confirmed scam, and the order did arrive, but the missing paperwork, the mid-order number switch, and the product looking off to the buyer are real concerns. Provisional; an independent batch test would settle whether the contents match.
