Testing: Labs & Certificates of Analysis
Particle Peptides publishes a COA vault of downloadable certificates, with current and archived batches, and states that each batch is tested by independent laboratories. On 9 October 2026 the vault held 92 documents from Liquilabs, which issues the current certificates, Apigenex, on older batches, and Eurofins laboratories in Slovakia, whose sub-reports cover metals and microbiology.
Newer Liquilabs certificates link the laboratory's own report, and those were checked at Liquilabs' own lookup on 9 October 2026, after it refused an invented code. Each covers assay and purity, identity by retention time, spectrum and mass spectrometry, microbial counts, endotoxin and seven elemental impurities, with the acceptable range printed for the last three.
All products are sold for laboratory research use only.
