Overview

Bronchogen is a synthetic tetrapeptide bioregulator directed at bronchial tissue within Khavinson's peptide research program. It is commonly cited in that literature for context on respiratory cell function and chronic airway conditions. The supporting evidence is largely non-Western, limited in scale, and not broadly replicated, so it should be viewed as preliminary.

How it’s thought to work

  • Proposed to act as a tissue-specific bioregulator for bronchial cells.
  • Reported to influence respiratory epithelial function in Russian studies.
  • Suggested to modulate expression of genes relevant to airway tissue.
  • Described as supporting normal bronchial cell maintenance.

Researched uses

  • Chronic respiratory condition research
  • Bronchial tissue function studies
  • Respiratory recovery in Russian reports
  • General geroprotection research

Commonly cited protocol

Typical dose~2-5 mg per day
FrequencyOnce daily over short courses in reported use
RouteIntramuscular injection or intranasal (research)
NotesAlso described in intranasal formulations in some sources.

Reconstitution

Commonly a 5 mg vial; 5 mg in 2 mL gives 2.5 mg/mL, so a 2 mg dose is about 16 units on a U-100 syringe.

Bronchogen dosage calculator

The calculator below is pre-filled with Bronchogen’s commonly cited vial size and dose. Adjust the vial amount, bacteriostatic water, or dose to match your own vial — it will show the exact insulin-syringe units to draw, the concentration, and how many doses the vial holds.

How much water you add is your choice — it doesn’t change your dose, only how many units you draw. Common:

Concentration

Doses per vial

📋 In plain English

Add 2 mL of bacteriostatic water to your 5 mg vial. That gives you about 2 doses of 2000 mcg. For each dose, draw 80 units into a 100-unit insulin syringe.

Cautions

  • Not FDA-approved; a research chemical outside its origin countries.
  • Human evidence is limited and largely non-Western.
  • Long-term safety is not established.
  • Source purity varies.
