Common questions
Quick answers about our products, testing and delivery.
Get in touch with our team about orders or products.
Contact usWhat are peptides?
Peptides are short chains of amino acids linked by peptide bonds. They are essential building blocks for proteins and play crucial roles in biological research and pharmaceutical development.
What is the legal status of research peptides?
Our products are research chemicals supplied only for in vitro laboratory use. They are not licensed medicines and must not be used in humans or animals. Whether a particular compound is regulated can depend on the substance and on its intended use, so we only supply orders for legitimate laboratory research and refuse any order where the intended use appears to be human consumption. If you are unsure about the status of a compound for your work, take independent legal advice.
What are your shipping times?
Orders placed before 2pm on a working day are dispatched the same day; later orders go out the next working day. All orders are sent Royal Mail Tracked.
Do you provide Certificates of Analysis (CoA)?
Yes. A Certificate of Analysis is included with every order. For a copy for a specific batch, use the request form above or contact us with your order number.
Which diluent should I use?
Most lyophilised peptides are reconstituted with bacteriostatic or sterile water, but some need a different diluent. Our Reconstitution guide covers diluent choice, volumes and storage for each compound, and the calculator on every product page works out concentrations for you.
