Frequently Asked Questions
General Questions
What 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.
Who can purchase peptides from your store?
Our peptides are intended for research and laboratory use only. They are available to qualified researchers, academic institutions, and licensed laboratories.
What purity levels do you offer?
Purity varies by compound and is stated on each batch's Certificate of Analysis, from independent third-party HPLC testing. Every order includes the CoA for its batch; sample certificates are in our CoA library.
Ordering & Shipping
How do I place an order?
Simply browse our product catalogue, add items to your cart, and proceed to checkout. You can complete your purchase as a guest or by creating an account.
What are your shipping times?
Orders placed before 2pm on a working day (Monday to Friday, excluding UK bank holidays) are dispatched the same day. Orders placed after 2pm, at weekends or on bank holidays are dispatched the next working day. Delivery is via Royal Mail, and tracking information is provided with every order.
How are peptides packaged?
All peptides are packaged in appropriate containers to maintain stability during transit. Products that need cold-chain handling are shipped with insulation to protect them in transit.
Product Information
Do you provide Certificates of Analysis (CoA)?
Yes. Every order includes the Certificate of Analysis for its batch, showing purity (HPLC) and identity (mass spectrometry). Sample certificates are in our CoA library.
How should peptides be stored?
Most lyophilised peptides should be stored at −20°C or below. Once reconstituted, store at 2–8°C, protected from light, and use within 4–6 weeks. See our Reconstitution Guide for full instructions.
What is the shelf life of your peptides?
When stored correctly, lyophilised peptides typically remain stable for 2–3 years. Reconstituted peptides have a shorter stability window and should be used according to product-specific recommendations.
Do you provide Bacteriostatic Water?
Not at the moment. Bacteriostatic water and our other lab supplies are currently unavailable. For help choosing a suitable diluent, see our Reconstitution Guide.
Technical Support
How do I reconstitute peptides?
Please refer to our detailed Peptide Reconstitution Guide for step-by-step instructions, including volumes, concentrations, and storage advice.
Can you provide custom peptide synthesis?
Yes. Please contact us to discuss custom synthesis requirements, including sequence specifications, modifications, and quantity needs.
Do you offer technical support?
Yes, our team is available to answer technical questions about our products, handling recommendations, and application guidance. Reach us via the Contact page.
Returns & Quality
What is your return policy?
Due to the nature of research chemicals, we do not accept returns. If you receive a damaged or incorrect product, please contact us immediately and we will resolve the issue.
What if I have quality concerns?
We stand behind the quality of every batch. If you have any concerns, please contact us with your order details and we will work to resolve the issue promptly.
