We operate a strict independent testing policy. No product is released for sale without batch-level analytical verification from an accredited third-party laboratory.
Manufacturer-issued Certificates of Analysis represent the supplier’s own quality control. Whilst these are a useful baseline, they do not constitute independent verification. Our policy requires that every batch is retested by a laboratory with no commercial relationship with the manufacturer, providing an unbiased and reproducible record of product quality.
High-Performance Liquid Chromatography (HPLC)
HPLC is the industry-standard method for quantifying peptide purity. Our testing uses reverse-phase HPLC to separate the compound from any impurities, producing a chromatographic profile that confirms the purity percentage of the active compound. We require a minimum purity of 98% for all products.
Mass Spectrometry (MS)
Mass spectrometry confirms the molecular identity and weight of the compound, verifying that the product corresponds to its stated molecular formula. This provides an additional layer of assurance beyond purity testing and guards against substitution or mislabelling.
Each CoA issued in relation to our products contains the following information:
Certificates of Analysis are available directly on each product page. If you require a CoA for a specific batch or need documentation in an alternative format for institutional compliance purposes, please contact us at info@morepeptides.co.uk with your order reference and the relevant product details.
We are committed to making our documentation as accessible and useful as possible for research customers.
We maintain records of all batch testing documentation in line with our data retention policy. In the event of a quality query or product recall scenario, we are able to trace all affected batches and communicate with relevant customers promptly.
Our products are supplied for in vitro research use only and are not manufactured as licensed medicinal products. Our quality assurance framework is designed to meet the standards expected by the research community, not to satisfy the requirements of a medicines manufacturing authorisation. Customers requiring GMP-certified materials for clinical or regulated research applications should contact us to discuss their specific requirements.
