Products & Research
Research peptides are short chains of amino acids (typically 2–50 residues) synthesized for in-vitro laboratory research only. They are used by scientists to study biological processes, receptor binding, cell signaling, and more. Our peptides are sold strictly for in-vitro research purposes and are not intended for human consumption or in-vivo use.

CertaPeptides is a research-peptide reseller, not a manufacturer, and does not run an in-house lab. Every product ships to its supplier's published batch specification (identity and purity, class-level). Selected lots are independently tested by Janoshik Analytical (Czech Republic); where a lot has a published report, its measured purity is shown and is searchable by batch code at /verify.
