Vanguard Laboratory: certificates on file

Vanguard Laboratory is printed as the issuing laboratory on 45 of the 415 public certificates of analysis in the Peptide Ranking index, 11 percent of the register. The certificates were published by 6 research peptide suppliers: Core Peptides (15), Licensed Peptides (15), Peptide Perfection (12), Atomik Labz (1), Prime Peptides (1) and Research Peptides (1). Umbrella Labs also names the laboratory on their pages, but we could not open a certificate to record.

The documents cover 16 peptides, most often BPC-157 (8), Triple-agonist class listings (8), TB-500 (4). Dates printed on the certificates run from 2025-06-29 to 2026-08-21. 45 of 45 print a lot number and 26 state a purity figure; the methods named are HPLC. Lot numbers appear on certificates from Core Peptides, Licensed Peptides, Peptide Perfection, Atomik Labz, Prime Peptides, Research Peptides.

A certificate describes the sample the laboratory received, not every unit a supplier later sells, so the lot number is what ties the document to a vial. We record what the documents print; we do not confirm them with the laboratory, and this page makes no statement about the laboratory's accreditation. To verify a certificate, quote its report number to the laboratory directly and check any accreditation claim on the accreditation body's register. Background: what ISO/IEC 17025 accreditation means, how to read a certificate, lot-level vs sample testing.
