PuriLab Analytical
Testing service at purilab.org that sells HPLC-UV purity and content tests to the public and publishes its results with a verification code; on 2026-11-02 a real code returned the laboratory's record and PDF and an invented code returned no match. Its site names no operating company and gives no street address (the shipping address is shown only after payment), so its existence as an identifiable business is not established and it is graded D. Reports are signed by a named lab director. The domain was registered in April 2026 and the earliest public result is dated July 2026. Identity is by HPLC against a reference, not mass spectrometry, and the laboratory states it holds no accreditation (checked 2 November 2026). Methods: HPLC-UV purity and content against in-house working standards.

About PuriLab Analytical
PuriLab Analytical is a laboratory name (Not stated (its terms are governed by California law)) that we could not establish as an independent operating laboratory, rated tier D in the Peptide Source Review lab directory. The laboratory's own terms state that it is not CLIA certified and holds no ISO 17025 accreditation (checked 2026-11-02). Because its independence is not established (tier D), each certificate naming it scores a flat 2.0 out of 10 and does not count toward the testing gate.
1 US peptide vendor in our audit publishes certificates naming PuriLab Analytical, led by JD BioWorks at 6.34/10. The reports cover HPLC-UV purity and content against in-house working standards.
How we graded PuriLab Analytical
Each check is the same for every laboratory (the rules). Checked 2026-11-02.
| Result | Check | What we found |
|---|---|---|
| Fail | L1 Real business | Checked 2026-11-02: the site names no operating company and no street address; the How It Works page says the shipping address appears only after payment, the terms ask for a suite and box number, and the contact page offers email, Telegram and WhatsApp only and says it does not discuss ownership. Reports name Max Barrett, Lab Director. The California business search (the state its terms name) blocked automated reads, so no registry entry could be matched. Update 2026-11-02: the California business search (run in the owner's browser) returns one match, PuriLab Analytical LLC (B20260397066), filed 1 September 2026, active, with a Whittier, California suite-and-box address. That is the only match for the name, but no registered purpose is on record yet (its first Statement of Information is due 30 November 2026), so the registry-match route in L1 is not yet met and L1 stays FAIL.
