What are peptides?
Peptides are small chains of amino acids, which are the building blocks of proteins. They occur naturally in the body and play important roles in many biological processes, such as cell communication, hormone regulation, and immune function. In research, peptides are used to study these processes and to explore how proteins and cells interact at a molecular level.
Are your peptides for human use?
No. The peptides are intended for research and laboratory purposes only. They are not approved or intended for human consumption, medical use, or administration. They should only be handled and used in accordance with standard laboratory safety guidelines.
Are peptides legally in the UK?
Yes, peptides are legal in the UK for research purposes. They are classified as chemical compounds and can be purchased and used for laboratory and scientific studies. However, they are not approved for human consumption or medical use and must always be handled in accordance with relevant safety and legal guidelines.
How do you ensure product quality?
We work closely with a trusted, long-established peptide synthesis partner that has been in the protein and peptide industry for over 20 years. Every peptide is carefully monitored throughout the synthesis process to ensure consistency and purity. After production, each batch undergoes rigorous testing, including HPLC, mass spectrometry, and other analytical checks, with full certificates of analysis provided to verify quality and traceability.
Do you offer purity certificates?
Yes. Every peptide batch comes with a certificate of analysis, detailing purity and verification testing. Each bottle also features a QR code that links directly to the test reports page online, providing full transparency and traceability for researchers.
Can you advise on dosage or usage?
No. We provide peptides for research purposes only and cannot provide guidance on human consumption or medical use. Peptides should only be handled and used in accordance with standard laboratory safety practices and research protocols.
Crown Peptides UK provides products that combine precision, quality, and trust. Our mission is simple: to offer the research community peptides of unmatched purity and consistency, backed by service you can rely on.
How should I store research peptides?
Peptides are supplied as lyophilized (freeze-dried) powders, which should be stored in a cool, dry place away from direct sunlight to maintain stability. Once reconstituted with bacteriostatic water or another suitable solvent, peptides should be stored in the refrigerator at the recommended temperature to preserve integrity and suitability for research use.
Do you ship internationally?
Yes, we ship peptides internationally. We also offer free international shipping on orders over £200. For first-time orders or larger quantities, we ask that you contact us to confirm that we can accommodate your request in compliance with local laws and regulations. All orders are carefully packaged to ensure they arrive safely and securely, and our team is happy to provide guidance to make the international shipping process as straightforward as possible.
How are peptides shipped?
All peptides are carefully packaged and sent safely in protective materials to prevent any damage during transit. This ensures that the products arrive in the best possible condition, with their quality and purity preserved for research use. Each shipment is handled with care to give customers confidence that their order will reach them securely.
Bulk Orders
Whether you need larger quantities for research or supply, we offer high-volume solutions while maintaining the same rigorous quality and testing standards for every batch. Please contact us to discuss your requirements.
Can I return or exchange a product?
Due to the nature of research chemicals, we cannot accept returns once an order has been dispatched. If your order arrives damaged or incorrect, we can arrange an exchange. Please contact our support team immediately so we can resolve the issue as quickly as possible.
