Kovera Labs: certificates on file

Kovera Labs is printed as the issuing laboratory on 34 of the 415 public certificates of analysis in the Peptide Ranking index, 8 percent of the register. The certificates were published by 3 research peptide suppliers: Eternal Peptides (13), Ascension Peptides (11) and Pure Peptide Labs (10).

The documents cover 16 peptides, most often BPC-157 (5), TB-500 (5), CJC-1295 + Ipamorelin blend (3). Dates printed on the certificates run from 2026-05-26 to 2026-10-08. 21 of 34 print a lot number and 10 state a purity figure; no method is named on the documents we parsed. Lot numbers appear on certificates from Ascension Peptides, Pure Peptide Labs.

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.
