The Lab Directory
A vendor’s testing claim is only as good as the lab behind it. Every lab named on a certificate on our vendor pages, graded by the same six published checks.

Verify portals
Every laboratory is graded on six checks (L1 real business, L2 independence, L3 verification route, L4 identity method, L5 track record, L6 accreditation on the accrediting body’s register), and its tier follows from them by a fixed table. A tier B- or better earns a certificate +2, tier C earns nothing, and tier D certificates score a flat 2.0. A laboratory is graded as soon as it is named in our records; one that no certificate on a vendor page names is listed below with its tier and has no effect on any score. The full rules
MDx BioAnalytical Laboratory
Tier A+United States · ISO/IEC 17025 accredited (register, peptide scope) · checked 2026-10-22
US laboratory (MDx BioAnalytical Laboratory, Inc.) using HPLC with mass spectrometry. Its CoA Search page takes the number printed on a certificate and returns the laboratory's own PDF; on 2026-10-21 real certificate numbers resolved and an invented one returned no match. Many reports in our records include endotoxin; none include sterility. Accredited by PJLA under certificate L26-502, active from 9 June 2026 to 31 July 2028, with a scope that includes peptides by HPLC-MS and endotoxins (USP <85>), as listed in PJLA's register on 22 October 2026.

Every certificate prints a search code that opens the laboratory's own copy at coas.freedomdiagnosticstesting.com, so a reader can confirm a report with the lab rather than the vendor. Reports cover LC-MS identity and HPLC purity with net content, and endotoxin and sterility appear on certificates from several vendors. No ISO/IEC 17025 accreditation is published.

College Station, Texas laboratory (Bioviridian Inc.) specialising in peptide analysis. Certificates carry a web verification code (COA####) and a QR code that resolve on bioviridians.com, and the reports we checked there matched the vendor copies. Reports cover MALDI-MS identity, RP-HPLC purity at 214 nm and HPLC content, and endotoxin appears on many certificates in our records. One certificate (COA3255) prints October 2025 dates, but its own chromatogram and the neighbouring reports show it was run in March 2026, so we treat the printed date as a misprint; the earliest other report we found is from December 2025 (checked 22 October 2026).

ILS Laboratories
Tier B+San Diego, CA (8222 Vickers St, Suite 106) · checked 2026-10-22
San Diego laboratory (ILS Labs Inc.) with a public certificate-verification flow: each certificate prints an access code that resolves through ils-lab.com/verify to a live record. PSR has resolved more than twenty ILS certificates first-hand across several vendors and lots, each matching the posted document. Identity on the ILS reports we hold is confirmed by HPLC against a reference standard, not by mass spectrometry. Extended panels add endotoxin, PCR sterility and heavy metals. PJLA's register listed its ISO/IEC 17025 certificate L25-631 as suspended from 22 October 2026 when we last read it. ILS's own website states that peptide testing is not within any accreditation scope (read 6 November 2026), so no ILS peptide report is an accredited result, whatever the register shows. Reports note that purity by area normalisation reflects peptide-related peaks only, so flat 100.00% values can occur under that method.

West Palm Beach, Florida laboratory whose certificates cite USP methods by chapter for every test, describe the vial received, and state what the analysis does not cover; endotoxin is reported on separate certificates. Identity is by FTIR rather than mass spectrometry. Its report links reject an invented address, but opening a genuine one requires a name, an email address and a verification code, so readers cannot check a report without identifying themselves (checked 22 October 2026). Reports we have read also name the upstream manufacturer of the material. Cited by several vendors in our records.

Fort Lauderdale, Florida laboratory whose main business is cannabis and kratom testing, with peptides as a secondary line. PJLA's register lists its ISO/IEC 17025 certificate L24-608-R1 as suspended, and the certificate's stated expiry of 30 September 2026 has passed (read 22 October 2026). Reports are signed by the laboratory director, Lise Berthe-Laurent, and carry HPLC purity and, on many, heavy metals and endotoxin. The verification link on reports resolves to the laboratory's homepage rather than to a record for the certificate, so a reader cannot confirm an individual report with the lab. Among the vendors we list it is used by one, Vyal Labs; its public cannabis and hemp reports go back to October 2022 and name several other clients (checked 22 October 2026).

1 vendor in our audit publishes certificates from this lab
Without certificates (5)
These laboratories are in our records, named by a vendor we list or have listed, but no certificate on a vendor page names them, so they have no effect on any score. Each is graded on the same six checks from its own public reports for any client (rule L0), and gets a profile when its first certificate appears: SafeCert Labs (tier D), Colmaric Analyticals (tier C), Liquilabs (tier B+), APIGENEX s.r.o. (tier B-), BioChex (tier D).
Lab testing, explained
How does a lab's tier change a vendor's score?
Each certificate is scored on our published lab rubric. A certificate from a laboratory graded A+, A, A-, B+, B or B- earns +2 for the laboratory, and +1 more when the laboratory passes L6 (ISO/IEC 17025 active on the accrediting body's register with a scope that covers peptide testing) and the certificate was tested on or after the date that accreditation became active. A tier C laboratory earns no laboratory points. A tier D laboratory is one whose independence we could not establish: every certificate naming it scores a flat 2.0 out of 10, the same as a self-issued certificate or one that names no laboratory, and it does not count toward the testing gate.
What makes a peptide testing lab credible?
We grade every laboratory by the same six published checks: it is a real business (L1), it is independent of the vendors whose products it tests (L2), a reader can check an individual report with it (L3), it identifies the peptide by mass spectrometry (L4), it has at least 12 months of reports for at least three unrelated clients (L5), and it holds ISO/IEC 17025 accreditation that is active on the accrediting body's own register with a scope that covers peptide testing (L6). The tier follows from the checks by a fixed table on our How We Rate page, and each laboratory's profile shows every result with its evidence link and the date we checked.
What is ISO/IEC 17025 accreditation?
ISO/IEC 17025 is the international standard for the technical competence of testing and calibration laboratories. An accredited lab has been assessed by an accrediting body for the methods listed in its scope. We count it only when the accrediting body's own public register shows it active with a scope that covers peptide testing; a laboratory's own claim, a logo on a certificate, or an accreditation for other kinds of testing does not count.
How do you verify a COA is real?
We match each Certificate of Analysis to the lab that issued it and, where the lab offers one, confirm the result through its verification portal using the batch or verification key printed on the report. We record whether that lookup succeeded, the named lab, and the panel tested, so a COA is only counted as verified evidence when it traces back to a real, named lab.
