Most-requested research peptides in the UK
The UK research market is currently driven by GLP-1 receptor agonists — Retatrutide, Semaglutide and Tirzepatide — alongside healing peptides like BPC-157, longevity compounds such as Epithalon and MOTS-c, and cosmetic blendslike GLOW and KLOW. Our catalogue covers all of these plus essentials like bacteriostatic water for reconstitution.
Quality, testing and storage
All peptides are supplied lyophilised in sealed vials. Once reconstituted with bacteriostatic water, store under refrigeration (2–8°C) and use within 28 days. Unopened lyophilised vials are stable for years when stored frozen. Certificates of analysis are available on request — we believe transparent testing is non-negotiable.
