Who We Are — UK Research Peptide Supplier
Astra Labs is a UK research peptide supplier focused on one thing the rest of the market consistently fails to deliver: full product transparency before you buy.
The UK research peptide market has a trust problem. Many suppliers list compounds with no independent testing data, no verifiable quality documentation, and no accountability. Buyers are expected to trust claims made by the same company selling the product. We think that is not good enough.
Astra Labs was built to do the opposite. Every eligible product we supply comes with a Certificate of Analysis from Janoshik Analytical — an independent third-party testing laboratory widely recognised across the UK and international research peptide industry for purity and identity verification. Every COA links directly to the Janoshik platform. Not a PDF. Not a screenshot. A live, independently verifiable result.
