Our Mission
Helix Peptides was founded with a singular mission: to provide researchers with the highest quality peptides at competitive prices. Research outcomes depend on the purity and consistency of starting materials. Every batch we stock arrives with a Certificate of Analysis from our supplier, and we commission independent laboratory verification of our own on top of it. We are UK based, we hold our stock in the UK, and we ship with tracking.
Why Researchers Choose Us
Quality Assurance
Every batch arrives with a Certificate of Analysis from our supplier documenting HPLC purity of ≥99%. We can send you the CoA for the batch you receive.
Certificates of Analysis
A batch-specific Certificate of Analysis is available for every product. Email us with your order number and we will send it over.
Independent Verification
We commission our own independent laboratory testing in addition to the documentation our supplier provides, so purity is not something we take on trust.
Fast UK Shipping
In-stock items ordered before 2pm Monday to Friday are dispatched the same working day. Pre-orders dispatch within 15 to 20 days. Free shipping on orders over £50, £2.99 below that. Every order ships with tracking.
