High-purity research peptides, made simple.

Kovalabs supplies research-grade peptides to UK laboratories and researchers. Every batch is tested by ILS Laboratories, an independent ISO 17025 accredited laboratory in San Diego, California, then 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

• Every batch and every strength tested by ILS Laboratories, not spot-checks on a supplier
• Purity by RP-HPLC, minimum 99%, with the chromatogram printed on the certificate
• Identity confirmed by HPLC-RTM against a reference standard
• Net peptide content reported per variant, not just purity
• Fentanyl screen on every batch as standard
• Certificates issued to Kovalabs by name, each carrying an access code you can verify with the lab directly
• 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

Every certificate we hold is published in full at our certificate archive, batch number and all.
