Independent Certifications & Third-Party Testing

Peptide Partners regularly audits its manufacturing partners with independent third-party laboratories. Independent analysis helps confirm the identity, quality, and purity of the research peptides we supply.

What we test for

  • Purity – laboratory analysis of identity and purity.
  • Endotoxin – screening for bacterial endotoxins.
  • Heavy metals – screening for metal contaminants.
  • Sterility – microbial screening for applicable products.

How to verify a certificate

Each product description lists a Manufacturer ID for the producer of that batch. Certificates of analysis (COAs) are issued by the testing laboratory and can be validated on that laboratory’s website.

To request the certificate for a specific product or batch, email support@peptiide.partners with the product name and the batch ID from your vial label or order.
