Peptide Warehouse
Listing paused pending vendor documentation (verified 2026-10-31): all 23 certificates on Peptide Warehouse's product pages come from "PRISM Analytical Laboratories", a laboratory PeptideGuide could not verify (the verify address printed on them returns 404 and belongs to an unrelated company; its own domain was registered on 2026-09-08), and they fail internal checks (the GHK-Cu certificate prints BPC-157's molecular weight, the Epithalon certificate reports PT-141, different compounds share lot numbers, and the PDFs were generated after the issue dates printed on them). Until the vendor documents its laboratory and corrected certificates, this review is kept for reference only and carries no purchase link.

Certificate provenance and integrity
All 23 product certificates on peptidewarehouse.ca are "PRISM Analytical Laboratories" reports for client "Peptide Warehouse Ltd." claiming HPLC-MS/MS, net content, ICP-MS heavy metals and LAL endotoxin. The laboratory cannot be verified: the verification address printed on every certificate, prismlab.com/verify, returns 404 and prismlab.com belongs to a digital dental-manufacturing company; the contact domain prismlabs.ca was registered on 2026-09-08, one day before the earliest issue date printed on the certificates (CJC-1295 DAC, report 2SSURU, 9 September 2026), and its site gives an email address and "Mississauga, Ontario" but no street address or accreditation. The certificates fail internal checks: the GHK-Cu certificate (report HHG6QV) prints an observed molecular weight of 1419.5 Da, which is BPC-157's, while the same lab's GLOW certificate prints 401.9 Da for GHK-Cu; the Epithalon certificate (D2GWYY) labels its result "PT-141"; the N-Acetyl-Semax-Amidate certificate (LDACJE) reports "N-Acetyl Selank Amidate"; different compounds share lot numbers (9177G on the CJC-1295, ipamorelin and CJC-1295/ipamorelin certificates, 2323H on DSIP and TB-500, 6522E on NAD+ and Melanotan 2); and all 23 PDFs were generated with jsPDF on 16–17 October 2026, after the issue dates printed on them (9 September to 9 October 2026). Re-checked 2026-10-31: the cited certificates are byte-identical to the copies downloaded on 2026-10-30.
