Bronchogen · 20MG

Bronchogen is a short-chain peptide bioregulator in the Khavinson cytomedin / cytogen class — synthetic short peptides developed by the Khavinson group at the St. Petersburg Institute of Bioregulation and Gerontology in Russia, proposed to function through tissue-specific gene expression modulation. Bronchogen is described as a bronchial / respiratory tract-derived peptide bioregulator within this peptide family, with the compound name derived from "bronchi" (the airways of the respiratory system). Some Russian academic sources report Bronchogen as a tetrapeptide preparation, though the chemistry documentation is less rigorous in mainstream Western scientific literature than the major characterized Khavinson peptides (Epithalon, Cortagen, Pinealon, Chonluten, Pancreagen, Cartalax). The compound is investigated in preclinical research as a representative of the broader Khavinson short-peptide bioregulator class for tissue-specific peptide pharmacology and comparative SAR studies. Researchers working with this compound should verify the specific chemistry against the supplier's Certificate of Analysis (COA) and rely on MS-verified molecular weight as the primary identity confirmation.
