High-purity research peptides, made simple.

Kovalabs supplies research-grade peptides to UK and international laboratories. Every batch is independently tested for purity by HPLC and mass spectrometry, stored in temperature-controlled freezers, and shipped same-day on orders placed before 2pm.

We started Kovalabs because the research peptide market is full of dodgy listings, slow shipping, and zero transparency. Our promise is the opposite: clear pricing, honest sourcing, real test data, and fast, traceable delivery.

Our standards

• Minimum 99% purity, verified by third-party HPLC
• Lyophilised vials, sealed under inert gas where applicable
• Cold-chain storage at −20°C
• Tracked next-day UK delivery on orders before 2pm
• Plain English research disclaimer at every step

Who we sell to
