Executive summary

Across 3 Finnrick lab tests, Qingfuji Trading is 3 pass / 0 fail for an overall pass rate of 100%. That is a real positive, but narrow: the entire current lab record is Retatrutide. For a buyer choosing Qingfuji specifically for Retatrutide, the dossier supports a reasonable candidate under batch-by-batch verification; for anything else offered over chat, Finnrick's data should not be borrowed.

The stronger hook is the mismatch between lab signal and accountability signal. Qingfuji presents as a contact-led vendor: Susan on a Macau-numbered WhatsApp line, a Los Angeles-area WhatsApp number, a Gmail address, and a listed China location, with no canonical public website or published verification system found. The obvious brand-matched domain was unregistered at capture, making future lookalike sites an authentication issue rather than a trust shortcut.

Corporate attribution is also unresolved. The only official entity lead is a name-similar Florida LLC; if it is related, the status and timing raise buyer-recourse concerns, and if it is not related, the investigation found no substitute verified operating company. Public social, review, coupon, and X/web affiliate scans were quiet, which reduces visible promotion-noise risk but leaves little independent market history to triangulate service reliability.

Finnrick's methodology view matters here because a small, single-product sample set can look clean while still being fragile under stricter grading assumptions. The full report keeps those issues separated: product quality signal for tested Retatrutide, and a distinct risk assessment for identity, channel authenticity, jurisdiction, and buyer documentation.

Inside the full report:

  • Retatrutide lab record with methodology-divergence charts and Appendix A data
  • Florida Division of Corporations filing analysis for the name-similar LLC
  • WHOIS and Wayback evidence for the brand-matched domain and missing web presence
  • WhatsApp, Gmail, and phone-identifier authentication controls
  • Reputation, review, Reddit, and X/web affiliate-promotion scan
  • Buyer-risk matrix covering corporate identity, channel authenticity, personnel, and jurisdiction

Risk assessment

  • Corporate identity and operating-entity ambiguity — high: No verified active legal entity was found; the name-similar QING TRADING LLC is inactive as of 2025-09-26 and its link to the current vendor is not independently proven.
  • Channel-authenticity and operational-transparency risk — medium: Qingfuji appears WhatsApp/Gmail-only; qingfuji.com was unregistered and no public policies, official-channel list, or COA-verification system were found.
  • Principal identification and accountability risk — medium: Only CHEN, QING appears on the name-similar Florida filing and Susan is first-name-only; no corroborating personnel background was found.
  • Jurisdiction and shipment-origin ambiguity — medium: Listed China location, Macau and Los Angeles WhatsApp numbers, and a possible Florida entity leave responsible jurisdiction and shipment/storage location unverified.
