Is it real? What we checked
Not confirmed The lab on most of PSPeptides' COAs, with a website and a working lookup on its own domain, but no company behind it that we could find: its site and certificates name none, and the Texas, New York, GLEIF and CMS records have no match. PSPeptides says its certificates come from accredited labs; we found no accreditation for North American Diagnostics, whose domain was registered in June 2026. How every lab name compares.
- Yes Its own website. nadiagnostics.com: “an independent U.S. laboratory bringing transparency to the research peptide and supplement industry”. Its services page prices tests for peptides and other research chemicals. [6] [7]
- No A registered company. Its site and certificates name no company, and we found no North American Diagnostics in Texas's or New York's business records, in GLEIF or in CMS's clinical-lab file. [8] [9] [10] [11]
- Partly A published lab address. 807 Brazos St, Austin, Texas, labelled “Laboratory” on its contact page and printed on its September 2026 certificate; no official record we could search lists a lab there. The phone number printed with it has a New Jersey (201) area code. [1] [12]
- No Accreditation, checked with the accreditation body. None found in the A2LA, PJLA or IAS directories, and it claims none on the pages we read. [2] [3] [4]
- No Names its scientists. Its site names no director or chemist; its certificates are signed by an “Analysis Administration Lead” with no qualification stated. [12]
- No Independent evidence that it operates. We found nothing independent of the lab and its client: no accreditation, licence, clinical-lab record, press report or paper. [11]
- Yes Independent of vendors. No tie to a vendor found. Its site says “We do not sell the products we test”, and its address and phone number appear on none of the 159 vendor sites we saved. [13] [1]
- Yes COAs can be checked with the lab. A lookup by test ID on its own domain: the ID printed on a PSPeptides certificate (NAD-0037963) returned a matching record for that client and batch. [5] [12]
- Under 1 yr Domain age. nadiagnostics.com was registered on June 1, 2026. [14]
- PSPeptides says “every certificate is from an independent, accredited laboratory”, and links 463 certificate files whose names begin “NAD-”. We found no accreditation for North American Diagnostics. One October 2026 PSPeptides certificate is from Vanguard Laboratory instead. [15] [12] [16]
