Active warning · 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.
