SupplyPeptides supplies UK-based laboratories and qualified researchers with lyophilised research peptides. Every compound we stock is sourced, independently verified, and held to a documentation standard that is deliberate — not decorative.
Our standard
Independently verified
Every batch is HPLC-tested by an accredited third-party laboratory before release. Purity and identity are documented on a published Certificate of Analysis.
UK stock, UK dispatch
Materials ship from UK inventory with same-day cut-off before midday UK time and tracked Royal Mail 24 delivery — insulated for short UK transit.
Research use only
We supply laboratories and qualified researchers. No dosing guidance, no human-use claims — clear RUO positioning on every product.
Certificates of Analysis
HPLC confirms purity. Mass spectrometry confirms identity against a reference standard. Results are published per batch so researchers can check the lot they receive before it reaches the bench. Browse the COA library.
