QUALITY ASSURANCE

Quality Is Not a Feature. It Is the Foundation.

At More Peptides, quality assurance is built into every stage of our supply chain — from manufacturer selection to final despatch. We believe that the integrity of your research depends on the reliability of your reagents, and we take that responsibility seriously.

Our Quality Philosophy

We do not believe in taking supplier claims at face value. Every product we stock is independently verified before it is offered for sale. Our quality assurance framework is designed to catch problems before they reach your laboratory — not after.

Manufacturer Selection

We work exclusively with synthesis and manufacturing partners who demonstrate:

Established track records in research-grade peptide production
Transparent documentation practices, including full batch records
Manufacturing processes aligned with recognised good manufacturing practices
Willingness to supply independently verified analytical data

We conduct ongoing due diligence on our supplier relationships. If a supplier’s standards fall short, we will cease sourcing from them.

Batch-Level Verification

Every batch of every product we stock is subject to independent third-party analytical verification before release for sale. We do not rely solely on manufacturer-issued Certificates of Analysis. Our internal process includes:

Products that do not meet our minimum purity threshold of 98% are not offered for sale.

Documentation

Every product available on our Website is accompanied by a Certificate of Analysis (CoA) from an independent accredited laboratory. The CoA confirms:

Product name and molecular formula
Batch number
Purity (% by HPLC)
Molecular weight confirmation (by MS)
Testing laboratory identity and accreditation
Test date

CoAs are accessible directly from individual product pages or available on request via info@morepeptides.co.uk.

Storage and Handling

We maintain appropriate storage conditions for all products in our inventory, including temperature-controlled environments for compounds requiring refrigeration or freezing. Our fulfilment process preserves cold-chain integrity from our facility through to delivery.

Continuous Improvement

Our quality framework is reviewed regularly. We actively seek feedback from research customers and incorporate improvements to our processes, documentation, and supplier relationships on an ongoing basis.
