ConfirmedThe privacy policy says the site is run by RCHQ LLC, operating as ResearchChemHQ, at 272 Calhoun Station Parkway, Suite C, PMB 1248, Madison, MS 39110; a PMB is a private mailbox at a mail-receiving business, not an office. Mississippi records, via OpenCorporates, hold RCHQ LLC (1543451), a limited liability company in good standing at that same mailbox address, with a statement of domestication filed on 20 April 2026, the filing for a company moving its home state to Mississippi. The phone number in that record is the WhatsApp number the 2023 researchchemhq.com shop gave. The same policy also names “ResearchChemHQ LLC”, which we did not find in any registry.

Gaps
What we couldn't verify about ResearchChemHQ
- 01Where RCHQ LLC was registered before it moved to Mississippi in April 2026, and whether “ResearchChemHQ LLC”, also named in its privacy policy, exists as a company.
- 02Where it operates or ships from: the only address it gives is a private mailbox, and Mississippi's own registry blocked our search.
- 03Its full current catalogue and prices, which are shown only to account holders.
- 04Whether any certificate in its library has been confirmed by the issuing laboratory, and why six RC-141 certificate images return “not found”.
- 05Whether researchchem.co, which sells products with near-identical codes, is connected to it.
