Common questions
Quick answers about quality, COAs, and shipping.
Are your peptides for human consumption?
No. Products are supplied strictly for laboratory research use only. They are not for human consumption, veterinary use, or medical use.
Do you provide Certificates of Analysis (COAs)?
Yes. Every batch is tested and a third-party COA is published for full transparency. You can browse the COA archive on our Lab Reports page.
Where do you ship from?
All orders are dispatched from the UK. Tracked services are available for end-to-end visibility.
How long does delivery take?
Most UK orders arrive within 1–3 working days after dispatch depending on the service chosen. You’ll receive tracking as soon as your order ships.
What payment methods do you accept?
We use PCI-compliant gateways for secure checkout. Available methods are shown at checkout and may vary by country.
How should I store the products?
Follow the guidance on each product page. In general, peptides are sensitive to heat, light, and moisture; store sealed, in a cool, dry, dark place.
Can I return items?
For safety and quality control we can't accept returns of opened laboratory reagents. If there is an issue on arrival, contact support and we'll help fast.
