Summary
Ovagen is a tripeptide bioregulator (Glu-Asp-Leu) developed by Professor Vladimir Khavinson, primarily targeting liver tissue. It supports hepatocyte function, liver cell regeneration, and protection against hepatic aging and disease. Ovagen is used in protocols for chronic liver disease, hepatoprotection, and metabolic liver conditions including fatty liver disease.
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.
