How Does Bronchogen Work?

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.

How to reconstitute Bronchogen

View guide

The materials you'll need and step-by-step instructions for safely mixing Bronchogen with bacteriostatic water.

Materials needed

Your Bronchogen vial (lyophilized)

Alcohol swabs

Bacteriostatic sterile water

3 mL syringes (Luer Lock tip)

25G or 27G needles (Luer Lock). Other gauges may also be acceptable.

Sharps container (optional)

Remove the caps

Remove the caps from both your Bronchogen vial and your bacteriostatic water vial.

Sanitize the rubber stoppers

Wipe down the rubber stoppers on both vials with alcohol swabs and let them dry for about 3 minutes.

Attach the needle

Take your 3 mL syringe and needle. Twist the needle's plastic hub into the Luer Lock tip on the syringe to secure it.

Draw the bac water

Pull back on the plunger to draw your desired volume of bacteriostatic water. If you overfill, just push the excess back in until you reach the right marker on the syringe.

How much bac water? Bronchogen typically comes in a 20 mg vial. We recommend 2 mL of bacteriostatic water, though anywhere between 1 mL and 3 mL is acceptable. For larger vials you can use up to 5 mL — more bac water makes microdosing easier, but insulin needles usually max out at 1 mL per injection. That means a lot of bac water might force you into multiple injections to hit your target dose. Unless you're microdosing, 2 mL per vial is a solid rule of thumb.

Insert the needle into the Bronchogen vial

With the bac water in your syringe, insert the needle into the Bronchogen vial at a slight angle to avoid pressure buildup.

Use a thin needle: Stick to 25G or higher to avoid damaging the rubber stopper. Higher gauge means a thinner needle.

Release the water gently

Let the water run gently down the side of the vial. Don't inject it forcefully.

Heads up: Sometimes the plunger pushes itself in as soon as the needle enters the vial. Hold the plunger back so you have full control over how fast the bac water enters.

Swirl to dissolve

Avoid shaking. Gently swirl, flip, and roll the vial to dissolve the powder.

Be patient: This usually takes 2 to 5 minutes of consistent swirling, mixing in a circular motion, and gently flipping the vial up and down. The water needs to run through the powder many times to fully dissolve it. Don't shake or get aggressive with it.

Check for full dissolution

The solution should be clear with no visible particles. If it's cloudy or clumpy, wait a minute and repeat the swirling step.

Cap, dispose, and store

Once you're done, cap the needle and dispose of it (ideally in a sharps container). Store the reconstituted Bronchogen vial in the fridge whenever it's not in use. It will stay good for approximately 30 days.

How to Store Bronchogen

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.

Lyophilized Storage

2–8°C, or -20°C for long-term preservation.

Reconstituted Storage

With bacteriostatic water, refrigerate at 2–8°C and use within 28 days.

How Long Should a Bronchogen Cycle 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.

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.
