Precision peptides, engineered for research.

Pepelabs synthesizes and distributes high-purity research compounds for accredited laboratories across the EU. Every batch we release is manufactured to strict quality standards and independently verified by third-party HPLC testing before it ships, with the resulting Certificate of Analysis published alongside the product.

How our compounds are made

Every peptide in our catalog is produced using solid-phase peptide synthesis (SPPS), the standard method for building peptide chains with precise, verifiable sequences. After synthesis, each compound is purified by preparative HPLC to remove synthesis byproducts and truncated sequences, then confirmed for identity and purity by analytical HPLC and mass spectrometry before it ever reaches our catalog.

Finished compounds are sterile-filtered and lyophilized (freeze-dried) into a stable powder, then sealed under inert atmosphere in glass vials — the same handling standard used across the research-peptide industry to preserve compound integrity in storage and transit.

Quality and documentation

We don't rely on our own in-house testing alone. Every production batch is sent to an independent third-party laboratory for HPLC purity and mass spectrometry identity verification, and the resulting Certificate of Analysis — batch number, measured purity, and testing method — is published on the corresponding product page so researchers can verify exactly what they're working with before they open a vial.

Who we serve

We work exclusively with qualified research professionals and institutions. Our catalog focuses on well-characterized peptide compounds used in laboratory research, supplied lyophilized for stability and shipped with the documentation researchers need to verify what they're working with. We don't market, describe, or sell any product for human or veterinary use.

Research use only

Pepelabs products are manufactured in the EU and are strictly for laboratory research use — not for human or veterinary consumption, diagnosis, treatment, or prevention of any disease. By ordering, you confirm you are purchasing on behalf of a qualified research context and accept responsibility for regulatory compliance in your jurisdiction.
