Zentra Labs was founded in 2019 by a collective of biochemists and quality engineers who saw a critical gap in the UK market — reliable, research-grade peptide supply with transparent provenance.
Every batch is tested using HPLC by independent UK-accredited laboratories.
We synthesise and store all compounds within the United Kingdom, enabling rapid dispatch, clear customs compliance, and cold-chain integrity that overseas suppliers simply cannot guarantee.
We communicate honestly about what we know and what we don't. Our research team maintains active literature reviews for every compound we offer, so you can make fully informed decisions.
Every decision at Zentra Labs flows back to four principles we've held since day one.
We do not ship without data. Every compound carries a full analytical report — HPLC purity, mass spectrometry confirmation, and residual solvent profiles.
Batch numbers, synthesis dates, storage conditions, and third-party lab results are publicly accessible. We hide nothing because there is nothing to hide.
We sell exclusively to verified researchers aged 18+. Products carry explicit research-only designations and we actively support ethical guidelines in peptide science.
Same-day dispatch before 2pm GMT. Tracked, temperature-aware shipping. Because research doesn't pause for delivery delays.
Every batch is synthesised, purified and verified to a single standard — uncompromising. From sourcing to dispatch, we obsess over the details so you can trust the data.

Used by research institutions and private labs across the UK & EU.
Tracked, temperature-aware shipping from our UK facility.

Six rigorous checkpoints stand between synthesis and your laboratory — because your research depends on it.
All peptides are synthesised using Fmoc solid-phase methodology in our controlled Cambridge facility, following pharmaceutical-grade procedures.
Every lot is tested by reverse-phase HPLC at ≥99% purity. Batches failing this threshold are rejected — no exceptions, no concessions.
Identity is confirmed via LC-MS. We verify molecular weight and fragmentation patterns against published reference spectra before any product is approved.
Selected lots are sent to UKAS-accredited external labs for blind verification — an independent confirmation that our in-house results are accurate.
Compounds are stored at −20 °C in monitored freezers. Temperature logging is continuous and recorded as part of each batch's traceability record.
Orders are packed in temperature-stable, tamper-evident packaging with COA included. Same-day dispatch before 2pm GMT via Royal Mail or DPD tracked.
