Verified by a
third party.
We exist to provide researchers with uncompromising access to high-quality research compounds. Quality, to us, is procedural — not promotional. It lives in the documents we keep, the partners we choose, and the batches we choose not to release.
Independent verification
Every batch is sent to an accredited third-party laboratory before release. We do not rely on supplier-issued certificates.
HPLC purity analysis
High-performance liquid chromatography establishes purity to ≥99%. Chromatograms are retained and available on request.
Mass spectrometry
Compound identity is confirmed by mass spectrometry, ensuring molecular weight aligns with the stated sequence.
Cold-chain storage
Lyophilised peptides are held at 2–8°C in controlled-environment storage with continuous temperature logging.
Shipping standards
Orders are dispatched in insulated, temperature-controlled packaging via tracked UK couriers — typically same working day.
Batch consistency
Each lot is held against reference data. Variation outside our internal tolerance results in the batch being withheld.
If a batch does not meet stated purity, we replace it. If a shipment fails in transit, we replace it. Our reship guarantee is not a marketing position — it is the working assumption of the laboratory.
