Summary
Cardiogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Arg) developed by Professor Vladimir Khavinson. It is a tissue-specific bioregulator for the heart and myocardium, designed to normalize cardiomyocyte function and support cardiac tissue regeneration. Research has demonstrated cardioprotective effects, improved cardiac rhythm, and benefits in recovery from ischemic injury.
Bronchogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Leu) developed by Professor Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology. It is a tissue-specific bioregulator designed for the bronchi and lungs, promoting normalization of bronchial epithelial cell function. Research suggests benefits for respiratory health, protection against pulmonary aging, and support for bronchopulmonary conditions.
Half-Life
Short (minutes); gene-regulatory effects persist longer
Short (minutes to hours); bioregulator effects are gene-mediated and longer lasting
