Who We Are

Built in a lab Designed for yours.

Zentra Labs is a trusted UK research peptide supplier founded in 2019 by biochemists and quality engineers. We provide high-purity research compounds with independent testing, transparent documentation, and controlled UK supply. We work with verified researchers, private laboratories, and research institutions that need clear Certificates of Analysis and consistent quality standards. As a peptide supplier UK laboratories can verify, and a peptide company UK researchers can contact directly, we publish batch documentation for every product.

Quality & Analysis

Certificates of Analysis are available on our website, providing researchers with clear information relating to our products.

UK-Based Supply & Dispatch

Products are stored and dispatched from within the United Kingdom, providing reliable and efficient domestic fulfilment.

Researcher-First Transparency

We believe in providing researchers with clear product information, accessible Certificates of Analysis and transparent research-only product designations.

What Drives Us

Our core values.

Every decision at Zentra Labs flows back to four principles we've held since day one.

Analytical Rigour

We do not ship without data. Every compound is supported by analytical reporting, including HPLC purity and identity confirmation.

Full Transparency

Batch information, testing results, and documentation are made available so researchers can review the material before experimental use.

Responsible Science

We supply exclusively for laboratory research use only. Products are not intended for human consumption, medical, therapeutic, diagnostic, or veterinary use.

Speed & Reliability

Same-day dispatch before 2pm GMT. Tracked, temperature-aware shipping. Because research doesn't pause for delivery delays.

From Synthesis to Shipment

Our quality process.

Six checks between synthesis and dispatch, because high-purity research materials depend on verifiable quality.

GMP-Aligned Synthesis

Peptides are synthesised using controlled solid-phase methods aligned with pharmaceutical-grade procedures.

HPLC Purity Analysis

Every lot is tested by reverse-phase HPLC. Batches that do not meet the required purity threshold are rejected.

Mass Spectrometry Confirmation

Identity is confirmed by LC-MS against expected molecular characteristics.

Independent Third-Party Testing

Selected lots are sent for external verification to support the reliability of in-house results.

Cold-Chain Storage

Compounds are stored under controlled low-temperature conditions with monitored handling.

Tracked UK Dispatch

Orders are packed carefully and dispatched with tracking. Same-day dispatch is available for eligible orders placed before 2pm GMT.
