Bronchogen Dosage Schedule

A focused two-week injectable course designed to support airway recovery and healthy lung function as part of a healthy-aging routine. Meant to be repeated a few times a year rather than run continuously.

Short Course Lung Support Cycle

3 weeks split across multiple phases, focused on longevity.

Daily dosing

Taken daily.

1.5 mg per injection

1.5 mg per injection, given just under the skin in the abdomen or thigh.

Bronchogen is a lab-made peptide bioregulator originally developed in Russia to support lung and bronchial tissue. Short cycles are typically used to help airways recover after strain and to support long-term respiratory function with age. The injectable dosing equivalent is roughly 1 to 2 milligrams per day.

What is Bronchogen?

Bronchogen is a very short, lab-made peptide designed to support lung tissue specifically. It works at the gene level inside lung cells, helping to calm inflammation and repair the lining of the airways. It's studied mainly for chronic lung conditions like bronchitis and COPD, especially in aging lungs.

Immunity

Research targets include immune cell activity, inflammatory response, and infection defense.

What Does Bronchogen Do?

It works its way into the proteins that package DNA in lung cells, helping switch back on genes that had gone quiet, particularly ones involved in tissue repair. At the same time, it dials down inflammatory signals and boosts production of natural lung-protective substances.

Frequently Asked Questions About Bronchogen

Straight answers on reconstitution, dosing, and safety, everything you need to research with confidence. For research reference only.

Bronchogen is a short bioregulator peptide (a tri- or tetrapeptide, variously reported as Ala-Glu-Asp or Ala-Glu-Asp-Leu depending on the source) developed within Vladimir Khavinson's line of tissue-specific 'bioregulator' peptides. It is designed to target bronchial and pulmonary epithelial tissue specifically, and is part of a broader family of organ-specific short peptides (e.g., Vesugen, Chonluten) that trace back to Russian gerontology research going back several decades. It is sold as a research compound, not an approved medication.

Bronchogen is described as working through gene-regulatory (epigenetic) effects on bronchial and lung tissue rather than by binding a specific receptor. Proposed effects reported by peptide vendors and bioregulator researchers include supporting normal turnover and repair of bronchial epithelial cells, helping regulate inflammation in the airways, and supporting mucociliary clearance and secretory IgA activity. These claims come mainly from Russian-language bioregulator literature and vendor/educational sites rather than large-scale peer-reviewed Western clinical trials, so they should be treated as preliminary research claims, not established medical facts.

Protocols vary by source and intended research context, so figures should be read as commonly cited conventions rather than validated medical dosing. For injectable (subcutaneous) use, sources commonly cite roughly 10 mg per day (with reported ranges anywhere from about 1-2 mg up to 10-20 mg) for a cycle of 10-20 days, sometimes repeated after a break. Oral capsule versions are also discussed, typically 1-2 capsules once or twice daily for 20-30 days followed by several months off. Cycle length and dose are frequently tied to a specific research context (e.g., general respiratory support vs. chronic bronchitis or asthma/COPD-focused protocols), with breaks of weeks to months between cycles being a recurring theme across bioregulator peptides generally.

As with most lyophilized (freeze-dried) research peptides, Bronchogen powder is generally recommended to be stored frozen (around -20°C), kept sealed, desiccated, and protected from light, where it is reported to remain stable for extended periods (commonly cited as 24+ months). Once reconstituted (typically with bacteriostatic water), the solution is generally recommended to be kept refrigerated (2-8°C) for short-term use within about a week, or frozen in single-use aliquots for longer storage. Repeated freeze-thaw cycles are commonly discouraged because they may degrade the peptide.

Across vendor and educational sources, reported side effects are described as minimal, mostly limited to mild injection-site reactions (redness, transient discomfort) with subcutaneous use, and occasional mild allergic reactions or gastrointestinal discomfort. Sources report no major safety signals such as hormonal, CNS, or metabolic effects in the available literature, and no cases of serious adverse events are commonly cited. However, independent, large-scale human safety data is limited, long-term effects are not well characterized, and these are not the findings of formally regulated clinical trials, so this information should not be treated as a guarantee of safety.

In the Khavinson bioregulator framework, it's common for researchers to discuss combining tissue-specific peptides (for example, pairing a respiratory-tissue peptide with an immune-support peptide) on the theory that different bioregulators target different organ systems. However, there is limited formal interaction data for these combinations, and claims about synergy are largely theoretical or anecdotal rather than established through controlled studies. Anyone considering combining compounds in a research setting should be aware that combined-use safety and effects are not well documented.

Educational and vendor content on Bronchogen most often discusses it in the context of chronic bronchitis, asthma, COPD, general age-related decline in respiratory function, and susceptibility to respiratory infections, drawing on decades of Russian gerontology research into bioregulator peptides. These associations come from a specific, geographically limited body of research literature (much of it not independently replicated in Western peer-reviewed trials), so they represent areas of stated research interest rather than confirmed clinical indications.

Bronchogen Reconstitution Guide

Bronchogen is supplied as a freeze-dried powder that must be mixed into a injectable solution before use. Available in 10mg, 20mg sizes.

20 mg lyophilized vial

Bronchogen is supplied as a freeze-dried powder that must be mixed into a injectable solution before use. Available in 10mg, 20mg sizes.

2 mL bacteriostatic water

Adding 2 mL of bac water to a 20 mg vial gives a workable concentration for syringe dosing. More water makes microdosing easier; less concentrates each draw.

Storage after mixing

Store the dry powder in the fridge or freezer for long-term keeping. Once mixed with liquid, refrigerate it and use within about a month. After reconstitution, keep the vial refrigerated and use within 30 days.

What Are the Benefits of Bronchogen?

What research says it may help with, and how it works in the body.

respiratory support

: Supports the health of airway tissue by helping regulate which genes are turned on or off in those cells.
: Helps keep the lining of the airways healthy.
: Helps control how lung cells build proteins, supporting normal lung tissue function.

antiaging

: Helps adjust which genes are active in cells of the respiratory system.
: May help counter the changes that occur in airway tissue as a result of aging.

Bronchogen Cycle Length: How Long Should It Last?

This breaks down how long a typical Bronchogen cycle runs and what research suggests happens at each stage. Research shows that staying on a peptide continuously, without a break, may make it less effective over time.

That's why most research protocols build in a break between cycles, often called a washout period, to let the body reset before starting again.
