Frequently Asked Questions
Answers to the most common questions about our research peptides, quality standards, and ordering process.
Research peptides are short chains of amino acids synthesised for in-vitro laboratory and scientific research. They are used by researchers to study biological mechanisms, receptor interactions, and cellular processes. All peptides sold by UK Peptide Lab are strictly for research use only and are not intended for human consumption.
Every peptide we supply is verified at ≥98% purity by HPLC (High-Performance Liquid Chromatography) analysis. We source exclusively from research-grade manufacturers with established quality control processes, and batch-specific analytical documentation is available for every product.
All orders are dispatched from our UK facility via Royal Mail 24 (next-day service), typically arriving within 1–3 working days. Orders placed before 2pm on a working day are dispatched the same day. Orders over £50 qualify for free shipping; orders under £50 incur a flat £3.99 delivery fee.
Yes. Every product includes batch-specific documentation covering HPLC purity data, mass spectrometry confirmation, and other relevant analytical results. Certificates of Analysis (CoA) are available for download directly from each product page.
Research peptides are legal to purchase in the UK for legitimate in-vitro research and laboratory purposes. They are not approved for human consumption, veterinary use, or any therapeutic application. Buyers must be aged 18 or over and confirm that products will be used solely for research.
