How can I ask about product documentation?
Use our Contact page before ordering and include the full product name and, where available, the relevant batch or lot reference. Documentation availability can vary by product and batch. Our documentation guide explains the main details to check on a report.
What should I check when comparing UK research peptide listings?
Check the exact product, stated quantity, physical form, batch or lot reference where available, supporting documentation, delivery terms and research-use policy. Our Research Peptides UK Product Information Checklist brings those checks together in one place.
What should I do if an order is damaged or incorrect?
Contact us promptly with your order number and details of the problem. Our Refund Policy explains the applicable returns and refund process.
How should a product be stored or handled?
Follow the product label, product page and any product-specific documentation. If information is unclear, contact us before opening or handling the item.
Who can place an order?
Customers must be at least 18 years old and must ensure that their purchase, possession and intended research use comply with applicable laws and regulations.
Where can I compare the available products?
Browse our research peptides and laboratory materials collection, or open the complete product catalogue for multipacks and other supplies. Each listing states the supplied quantity.
Does a report cover every batch of a product?
No. A report relates to the sample and batch it identifies. Check the product name, batch reference, laboratory and report date against the item being considered. Read our product and batch documentation guidance and our detailed documentation guide, and contact us if the match is unclear.
Where can I find the Tesamorelin size comparison?
The Tesamorelin 10mg page compares the 5mg and 10mg laboratory listings and explains the supplied quantity and physical form. The Reta guide's pack table provides a separate comparison for Retatrutide vials and multipacks.
Does a “research use only” label mean a material is legal to sell in the UK?
No. Intended research use and legal permission to supply are separate questions. Some materials may be subject to medicines law or other restrictions regardless of the wording on their labels. The MHRA stated on 15 October 2026 that retatrutide is not authorised in the UK and that products sold as retatrutide outside legitimate clinical trials are supplied illegally. Read the MHRA's official notice and our Research Use Policy. Nothing on this website should be taken as confirmation that supply of any particular material is lawful.
