PEPTIGEN
LABS
// Quality Standards

British supply. Research-grade standards.

Peptigen Labs is built around documentation rigour, careful sourcing, and clear, defensible labelling. Below is a summary of how we approach quality across the catalogue.

Batch Documentation

Every Peptigen Labs product is presented with clear strength, storage guidance, batch identification, and research-use-only labelling.

Purity Verification

Suppliers are vetted with documentation in mind. Where available, a Certificate of Analysis (COA) can be uploaded against a product or supplied on request.

Cold Storage & Handling

Lyophilised material is held at 2-8°C in our facility. Dispatch packaging is sealed and padded — lyophilised material remains stable for short UK transit at ambient temperature.

Supplier Screening

Sourcing is selected for documentation rigour and consistency rather than the cheapest available material.

Packaging Integrity

Tamper-evident packaging, clear labels, and SKU/batch identifiers across all dispatched units.

Research-Use Transparency

Every product page, label, and order acknowledgement reaffirms the strict research-use-only positioning of all Peptigen Labs products.
