Every Spartan Peptides batch is verified to a ≥98% purity standard by HPLC (with mass spectrometry confirming molecular identity), and the original lab reports are published in a public COA library that states “6 Compounds Verified” (read 2026-09-24) rather than one report per catalog item. The reports we reviewed were issued by MZ Biolabs, an independent analytical laboratory at 2102 N Country Club Rd, Tucson, AZ, and signed by analytical chemist Ken Pendarvis — observed purity ran 99.4–99.97% across the compounds checked. No accreditation is printed on the certificates. A Certificate of Analysis lets researchers confirm identity and purity before use. On 14 October 2026 Prof. Peptide drew three of the six at random and opened each one at MZ Biolabs' own certificate viewer through the QR code it prints, after an invented ID was refused; all three name Spartan Peptides as the client and share one lot code, PEP-04-26.
