Particle Peptides independently analyzes every product across six parameters: purity, molecular identity, peptide content, bioburden, endotoxin levels, and heavy metals — covering both class 1 and class 2 heavy metal contaminants. Particle Peptides states they are the only company in the market to present independent analysis of all six parameters across their entire product range. All testing limits are established in accordance with the European Pharmacopoeia (Ph. Eur.). Every Certificate of Analysis we reviewed was issued by Liquilabs s.r.o., an independent analytical laboratory in Zlatníky-Hodkovice, Czechia, and carries a QR code to verify the results online — each is a 12-page report covering purity by RP-HPLC (identity confirmed by UV spectrum and retention time), peptide assay, microbial count, bacterial endotoxin, and heavy-metal elemental impurities across seven elements, all to USP and Ph. Eur. methods. Particle Peptides states its compounds are produced by a manufacturer inspected by the FDA, NMPA, EMA, TGA, and MFDA and compliant with cGMP, ISO 9001, and ISO 13485. All Certificates of Analysis are publicly accessible through a dedicated COA Vault on their website at particlepeptides.com/en/coa-vault.

Particle Peptides stores all compounds in temperature-controlled environments to preserve peptide integrity from storage through delivery. The company emphasizes long-term customer relationships through recurring discounts and responsive customer service operating from their European base.com.
