01Mechanism of Action

Parameter
Bronchogen
GHRP-6
Primary target
Bronchial epithelial cellsKuzubova 2015
Ghrelin receptor (GHS-R1a)Bowers 1990
Pathway
Tissue-specific bioregulation → epithelial cell differentiation → ciliated cell restoration
GHS-R1a → Gαq → Ca²⁺ → GH release; central appetite driveBowers 2002
Downstream effect
Reversal of goblet cell hyperplasia, squamous metaplasia elimination, restoration of ciliated epithelium, normalized secretory IgA and surfactant protein B productionKuzubova 2015Titova 2017
GH pulse + strong appetite stimulation; modest IGF-1 elevationBowers 2002
Feedback intact?
Origin
Synthetic tetrapeptide (Ala-Glu-Asp-Leu) from Khavinson bioregulator framework
Synthetic hexapeptide; first-generation GHRP from Bowers groupBowers 1990

05Administration Protocol

Parameter
Bronchogen
GHRP-6
1. Research context only
Bronchogen has been studied exclusively in animal models and organotypic tissue culture. No approved formulation or human administration protocol exists.
Add 2 mL bacteriostatic water to 5 mg vial → 2.5 mg/mL.
2. Animal model protocol
In rat COPD models, tetrapeptide administered for 30-day course following 60-day NO₂ exposure. Route and exact dosing not specified in abstracts.Titova 2017Kuzubova 2015
SQ — abdomen. Rotate sites.
3. Organotypic culture
Bronchial tissue explants from young (3-week) and aged (18-month) rats cultured in medium containing 0.05 ng/mL bronchogen, demonstrating tissue-specific stimulation.Zakutskiĭ 2006
Pre-meal for appetite support; pre-sleep for GH alignment.
4. Khavinson bioregulator tradition
Part of Russian peptide bioregulator framework emphasizing tissue-specific low-dose effects. Typically administered parenterally in related peptides from this series.
Lyophilised: room temp. Reconstituted: refrigerate ≤30 days.
5. Needle
29–31G, 4–8 mm insulin syringe.
