Quality and standards

Published analyses, not promises.

Our peptides are produced by solid-phase peptide synthesis with manufacturing partners. The certificates we publish are analyses by an independent third-party laboratory (Janoshik), reproduced as they are: some ordered by Peptinium Labs, others by a third party, the client being stated on each certificate.

We only publish the analysis reports we actually hold: the certificates below show the compound, the date and a verification key so you can check them directly with the laboratory. A product without a displayed certificate is a product whose analysis has not been published yet.

Sourcing: Identified manufacturing partners.
Purity: HPLC analyses by a third-party laboratory.
Transparency: Published CoAs, verifiable online.
