Doses studied in research Animal or lab studies only
What was given to people (or animals) in published studies and official labels, each linked to its source. This is not a recommendation: study products, purity and supervision differ from research-grade vials.
Animal studies: Rats with NO2-induced COPD-like lung damage received bronchogen for 1 month (dose not stated in the abstracts); tissue-culture studies used 0.05 ng/ml; other work is in cell lines, DNA and tobacco plants.
No human studies were found; nearly all research comes from the developer's group. Doses in animal studies do not translate directly to people.
What the research says
Bronchogen (Ala-Glu-Asp-Leu, AEDL) is a St. Petersburg 'peptide bioregulator' marketed for the lungs; the evidence is two small rat COPD-model studies plus cell, DNA and even plant experiments, nearly all from the developer's network. No human studies were found.

Modulating Effect of Peptide Therapy on the Morphofunctional State of Bronchial Epithelium in Rats with Obstructive Lung Pathology.Animalssize not reported1 month of treatmentTetrapeptide Bronchogen therapy in a rat COPD model
In rats with NO2-induced COPD-like lung damage, one month of Bronchogen reportedly reversed bronchial epithelial remodeling (goblet cell hyperplasia, metaplasia, emphysema), increased secretory IgA and reduced neutrophilic inflammation.
Study details
- Studied
- Rats with COPD modeled by 60-day intermittent NO2 exposure
- Main outcome
- Bronchial epithelium remodeling, secretory IgA, cytokines
- Authors' conclusion
- One month of Bronchogen eliminated signs of bronchial epithelium and lung remodeling, raised secretory IgA and normalized cell composition and proinflammatory cytokines, reflecting reduced neutrophilic inflammation.
- Limitations
- Rat model; sample size not stated in abstract.
-
[ANTIINFLAMMATORY AND REGENERATIVE EFFECT OF PEPTIDE THERAPY IN THE MODEL OF OBSTRUCTIVE LUNG PATHOLOGY].Animalssize not reportedBronchogen course with bronchoalveolar lavage analysis
Same rat COPD model: Bronchogen normalized lavage-fluid cell composition and pro-inflammatory cytokines and raised secretory IgA and surfactant protein B.
Study details
- Studied
- Rats with COPD modeled by 60-day intermittent nitrogen dioxide exposure
- Main outcome
- BALF cell composition, cytokines, secretory IgA, surfactant protein B
- Authors' conclusion
- Peptide treatment reduced neutrophilic inflammation, restored bronchial epithelium structure and increased secretory IgA and surfactant protein B.
- Limitations
- Rat model; sample size not stated in abstract.

Peptides tissue-specifically stimulate cell differentiation during their aging.Cells / labIn vitro expression study in young and late-passage (aging) cultures
In aging human bronchial epithelial cell cultures, Bronchogen stimulated expression of differentiation factors CXCL12 and Hoxa3.
Study details
- Studied
- Human embryonic pancreatic and bronchial cells and prostatic fibroblasts in culture
- Main outcome
- Expression of CXCL12, Hoxa3 and WEGC1 differentiation factors
- Authors' conclusion
- Vesugen stimulated differentiation factor expression in fibroblasts, with a stronger effect in aged cultures, which may be a mechanism of geroprotective effect.
- Limitations
- In vitro cell culture only.
-
Epigenetic mechanisms of peptidergic regulation of gene expression during aging of human cells.Cells / labIn vitro gene expression and promoter DNA-methylation analysis with KEDW and AEDL peptides
In aging bronchial cell cultures, AEDL altered expression of several lung genes (e.g. NKX2-1, SCGB1A1), possibly via promoter methylation changes; other genes were unaffected.
Study details
- Studied
- Ageing human pancreatic and bronchial epithelium cell cultures
- Compared with
- Untreated cultures of different age
- Main outcome
- Gene expression and promoter methylation of PDX1, PAX6, NGN3 and other genes
- Authors' conclusion
- Changes in promoter methylation might explain the age- and peptide-induced changes in expression of PDX1, PAX6 and NGN3 in pancreatic cells; other genes appear controlled by other mechanisms.
- Limitations
- Cell cultures only; mechanism, not efficacy.
-
Effect of the peptide bronchogen (Ala-Asp-Glu-Leu) on DNA thermostability.No new dataDifferential scanning microcalorimetry of DNA melting with bronchogen
Calorimetry study: Bronchogen raised the melting temperature of isolated DNA by 3.1 °C, acting as a DNA-stabilizing agent.
Key resultBronchogen increased the melting temperature of DNA by 3.1°C in a narrow range of molar ratios
Study details
- Studied
- DNA from calf thymus and mouse liver
- Main outcome
- DNA melting temperature and enthalpy
- Authors' conclusion
- Bronchogen acts as a DNA-stabilizing agent, not specific for AT or GC pairs, binding strongly and occasionally to both strands.
- Limitations
- Biophysical in vitro study.

Bronchogen: questions people ask
What is Bronchogen?
Russian short-peptide bioregulator. One of the Khavinson "bioregulator" peptides from Russian aging research, marketed for the bronchi and lungs. Evidence comes mainly from Russian cell and animal studies.
How much does Bronchogen cost?
The cheapest Bronchogen from an independently tested vendor is $0.750 per mg (Uther, Bronchogen 20mg (10 Vials / Kit), $150.00). Across 14 listings from 13 vendors the median is $2.70 per mg.
Where can I buy Bronchogen?
13 vendors tested by Finnrick sell Bronchogen. The cheapest per mg right now: Uther ($0.750), Qingdao Sigma Chemical QSC ($1.18), Bulk Peptide Wholesale ($1.25). 2 of them publish a lab report (COA) for Bronchogen; compare lab scores and reports in the table above before buying.
How much bacteriostatic water for 20 mg of Bronchogen?
Adding 2 mL of bacteriostatic water to a 20 mg vial of Bronchogen gives 10 mg/mL: each 10 units on a U-100 insulin syringe holds 1,000 mcg. With 1 mL it's 20 mg/mL (2,000 mcg per 10 units); with 3 mL, 6.667 mg/mL (666.7 mcg per 10 units). More water makes small amounts easier to measure. Mixing charts: 10 mg, 20 mg.
Is Bronchogen FDA approved?
Sold as a supplement in Russia; not approved in the US. Research use only.
Can Bronchogen be compounded in the US?
Not an FDA-approved drug and not nominated for FDA's 503A bulks list, so US pharmacies can't legally compound it. Compounding status for every peptide.
Does Bronchogen work? What does the research say?
Evidence grade C (mostly animal studies), from 5 papers: No human studies; two rat COPD-model studies from the developer's group plus cell, DNA and plant experiments. Bronchogen (Ala-Glu-Asp-Leu, AEDL) is a St. Petersburg 'peptide bioregulator' marketed for the lungs; the evidence is two small rat COPD-model studies plus cell, DNA and even plant experiments, nearly all from the developer's network. No human studies were found. See the papers.
What dose of Bronchogen was used in studies?
Bronchogen is tested only in animals or cells. Rats with NO2-induced COPD-like lung damage received bronchogen for 1 month (dose not stated in the abstracts); tissue-culture studies used 0.05 ng/ml; other work is in cell lines, DNA and tobacco plants. These are amounts used in published studies or official labels, not a recommendation.
