Bronchogen
Bronchogen (Respiratory Bioregulator)
Bronchogen is a short-chain tetrapeptide (Ala-Glu-Asp-Leu) developed by the St. Petersburg Institute of Bioregulation and Gerontology as a tissue-specific bioregulator targeting bronchial and pulmonary epithelial tissue. It is primarily used to support respiratory function, promote bronchial epithelial regeneration, and is investigated for conditions such as chronic obstructive pulmonary disease (COPD), bronchitis, and age-related decline in lung function. It belongs to the Khavinson peptide family, which are short peptides designed to restore gene expression patterns in specific tissues.
Mechanism of Action
Bronchogen acts as a gene expression regulator by penetrating cell nuclei and interacting with histone proteins and specific DNA promoter regions associated with bronchial epithelial cell differentiation and renewal. This epigenetic-like interaction is proposed to normalize transcription of genes involved in mucociliary clearance, epithelial integrity, and local immune defense within the bronchopulmonary system. The peptide is thought to restore homeostatic signaling in aged or damaged bronchial tissue by upregulating cytoprotective and regenerative pathways, including those governing surfactant production and ciliary function.

Dosing Protocols
Morning, 30-40 minutes before meals on an empty stomach
Cycle: 10-day course, repeated 2-3 times per year
Sublingual administration is the preferred route used in clinical protocols from the originating research institute; allows partial bypass of first-pass hepatic metabolism for improved bioavailability of intact peptide fragments.
Morning on an empty stomach, 30 minutes before breakfast
Cycle: 10-day course, 2-3 cycles per year with at least 2-month intervals
Oral capsule form is widely available; bioavailability may be lower than sublingual due to gastric degradation, but clinical protocols have been published using oral administration with reported efficacy.
Safety & Side Effects
Bronchogen has a favorable short-term safety profile based on the Russian clinical literature, with no serious adverse events reported in published studies involving elderly patients over multi-year follow-up; however, long-term independent safety data outside of the originating research group are limited, and it is not approved by the FDA or EMA. It is sold as a dietary supplement or research compound in most Western countries, and individuals with active respiratory malignancies, autoimmune pulmonary diseases, or those on immunosuppressive therapy should consult a physician before use.
Possible Side Effects
- !Generally well-tolerated with minimal reported adverse effects in published studies
- !Mild transient nausea in sensitive individuals when taken on empty stomach
- !Localized sublingual irritation or mild tingling with sublingual administration
- !Headache reported rarely, particularly during initial days of use
- !Theoretical risk of allergic reaction in individuals with peptide hypersensitivity
- !Mild fatigue during first few days of a course in some users
Interactions
- -May potentiate effects of bronchodilators (e.g., beta-2 agonists) through complementary improvements in airway epithelial function - monitor for additive respiratory effects
- -Theoretical synergistic effect with other Khavinson peptides (e.g., Crystagen, Ventfort) when used in combination protocols - no safety concerns identified but data are limited
- -May enhance mucociliary clearance, potentially altering absorption kinetics of inhaled corticosteroids
- -Use caution in patients on immunomodulatory agents given the peptide's proposed effects on local pulmonary immune regulation
- -No known pharmacokinetic interactions with common medications, but drug interaction data are largely absent from independent peer-reviewed sources
Cost & Where to Buy
Sold primarily through European and Russian supplement suppliers and a small number of peptide research vendors; standard packaging is 20 capsules of 10mg each (one 10-day course); cost varies by supplier region, capsule count, and product purity certification.
