Reference for researchers
Plain-language guides to working with research peptides — storage, reconstitution, reading a Certificate of Analysis, purity testing and the UK legal position.
What are research peptides?
A plain-language introduction to research peptides: what they are, how they are made, why laboratories use them, and what research-use-only means in practice.
Storing, handling and reconstituting lyophilised peptides
How to store lyophilised research peptides, bring a vial to room temperature, reconstitute without degrading the compound, and aliquot for repeat use.
Understanding a Certificate of Analysis
What a Certificate of Analysis for a research peptide contains, how to read purity and identity results, why independent testing matters, and the difference between purity and net peptide content.
Peptide purity and testing methods explained
How research peptides are tested: reverse-phase HPLC for purity, mass spectrometry for identity, amino acid analysis for net content, and what each method can and cannot tell you.
Reading a peptide specification: CAS, formula, sequence and molar weight
How to read the technical specification of a research peptide — CAS number, molecular formula, molar weight, sequence notation, terminal modifications and non-standard residues.
Batch numbers and traceability
Why every vial of a research peptide should carry a batch number, how batch-level traceability works, and how a QR code links a vial to its Certificate of Analysis.
Built around documentation and traceability
Independent third-party testing
Every batch we supply is tested by an independent UK laboratory, with a Certificate of Analysis available on request.
Batch traceability
Every vial carries a batch number linked to its certificate by QR code, so the testing behind it can be traced.
Full technical documentation
CAS number, molecular formula, molar weight, sequence, storage guidance and cited literature for every compound.
UK-based supply
Dispatched from Warrington, Cheshire within one to two business days. No overseas fulfilment.
Plain-language reference
A knowledge base written for researchers: storage, reconstitution, reading a COA, purity testing and the UK legal position.
Research-use only, throughout
Everything we supply is sold, labelled and invoiced strictly as a research compound for in-vitro laboratory use.
Why the business was started
The founders' interest began with peptides and the science behind them. As they became more involved in the sector they kept meeting the same problems: inconsistent products, limited transparency, unclear sourcing, and too often no meaningful independent testing to confirm a product was what it claimed to be.
Premium Lab Peptides was built to hold a higher standard — sourcing through carefully selected manufacturing partners, applying strict quality control through the supply chain, and using independent third-party laboratory testing to give confidence in identity, purity and consistency. Research should rest on reliable materials and accurate information, not exaggerated claims.
Next-working-day tracked delivery across the region
Based in Warrington, Cheshire, we supply laboratories and researchers throughout Greater Manchester, Lancashire and Cheshire — and UK-wide.
