## About

CertaPeptides is a European research peptide reseller operated by CERTALAB S.R.L. (Romania). We supply lyophilized research peptides for scientific and laboratory research purposes only, against the supplier's published batch specification (identity and purity, class-level). As a reseller, we do not run HPLC, MS, endotoxin, or bioburden testing in-house. Selected lots are independently tested by Janoshik Analytical (Czech Republic) for HPLC purity and MS identity (endotoxin and bioburden as add-on panels, noted on a report when present), and those reports are published and searchable by batch code.
