Vanguard Laboratory is the name printed in the laboratory position on 45 documents in the register, published by Atomik Labz, Core Peptides, Licensed Peptides, Peptide Perfection, Prime Peptides and Research Peptides. Every one of them carries a lot identifier; 26 are dated, the earliest 2025-06-29 and the latest 2026-08-21; 26 print a purity figure, between 98.14% and 99.8%. The method printed is HPLC. The documents are image and pdf, covering 17 distinct peptides.
The Core Peptides file records the laboratory as A2LA-accredited and in Olympia, Washington, with certificates that cite A2LA Certificate #6377; the documents we opened under this name cover HPLC identity and purity, with no mass spectrometry, endotoxin or sterility result shown.
A laboratory name on a certificate is the supplier's statement that this laboratory produced the report. The desk records it as printed and does not merge spellings, rank laboratories or confirm the report with the laboratory on a reader's behalf; what a name does make possible is the question, which is set out in How to verify a peptide COA with the lab and Peptide testing labs explained. A purity figure in the table is the laboratory speaking about one lot on one date, not a score.
