Bronchogen is sold here for laboratory research, in 1 size (20mg), starting at $80.00 a vial. Every batch arrives with a certificate naming the test that identified it, the test that measured its purity, and the date each was run. It is not an FDA-approved medicine. Research use only, and never for people or animals.

What is Bronchogen?
Chemically: molecular formula C18H30N4O9, average mass 446.5 g/mol (PubChem CID 11690869). Those figures are what the identity test on a certificate is read against.
Short synthetic peptide from the Khavinson "bioregulator" series.
Mechanism is not established in the conventional receptor sense. The originating group proposes that these peptides act epigenetically, entering cells and binding directly to specific DNA sequences to modulate transcription of tissue-relevant genes, with molecular docking used as the supporting method. That is a hypothesis about a mechanism, not a demonstrated pathway, and it has not been independently confirmed outside the groups that advanced it.
Appears in a preclinical literature of organotypic tissue culture, rodent models and gene-expression work, largely produced by the St Petersburg Institute of Bioregulation and Gerontology and collaborating Russian institutes. A substantial share is published in Russian, in journals with limited international circulation.
No approved product outside Russia, no pharmacopoeial monograph, no independently replicated mechanism, and no controlled trial meeting United States or European standards. The volume of commercial writing about this series greatly exceeds what its cited sources report.
Bronchogen for sale: 20mg vials, price per mg
Bronchogen is sold in 1 size here, 20mg, from $80.00 a vial. The per-mg column is the honest comparison between sizes; the two tier columns show what ten and twenty vials of one size bill at, because the volume discount is per size and mixed sizes do not combine.
| Size | One vial | Per mg | 10 vials −10% | 20 vials −15% | Availability |
|---|---|---|---|---|---|
| Bronchogen 20mg | $80.00 | $4.00 | $720.00$3.60/mg | $1,360.00$3.40/mg | Backordered — waitlist |
Bronchogen discounts: bulk pricing, Subscribe & Save, and codes
Three things move this price and nothing else does: how many vials of one size are on the order, whether that order repeats, and one code. The fourth column prices each route against the 20mg vial.
| Buying option | Takes off | When it applies | 20mg at this option |
|---|---|---|---|
| One vial, one time | — | Any order | $80.00 |
| 10–19 vials of one size | 10% | This order | $720.00$72.00 a vial |
| 20 vials of one size | 15% | This order | $1,360.00$68.00 a vial |

| Subscribe, every 3 months | 2% | Shipment 2 onward | First $80.00, then $78.40 |
| 10 vials on a monthly subscription | 10%, then 6% more | Shipment 2 onward | First $720.00, then $676.80 |
| Sign-up code | 10% of the order | One use, dead 24 hours after signup | $72.00 for one vial |
| Friday newsletter code | 5% of the order | Live 24 hours, a new one each Friday | $76.00 for one vial |
| On-site offer code | 5% of the order | Live 30 minutes from when it appears | $76.00 for one vial |
| Free standard shipping | The shipping charge | Orders over $200 | 3 vials |
The first three stack; the codes do not. A volume discount comes off the line, a subscription cadence comes off that same line from shipment 2, and one code comes off what is left. One code per order, never two. A subscription runs a minimum of two shipments and can be cancelled once the second has shipped, and the first shipment always bills at today's eligible price with no cadence discount on it. The lowest this record ever bills is $3.20 per mg: twenty 20mg vials on a monthly subscription, from shipment 2 onward.
Every figure above is what you pay; nothing is added at checkout — dispatch and delivery work the same on every order.
Where to buy Bronchogen: five checks before you order from anyone
Bronchogen for sale, or Bronchogen peptide for sale, means this page: one record, 1 size, a lot certificate for each. You can buy Bronchogen online here with guest checkout; verified in-stock orders placed before 12 PM Pacific are dispatched the same day.
Run these on us too. A supplier who cannot pass them is asking you to take their word for it, and their word is the one thing a certificate exists to replace.
- Check the certificate on the lab’s own site, not ours.
- See whether it was written for the seller.
- Match the lot number on the paper to the one on the vial.
- Look for a method and a date next to every number.
- Make sure identity was tested, not assumed.
Each of those is worked through, with what a failed check actually looks like, on verifying a certificate.
The Bronchogen certificate: lot, purity, identity, and how to verify it
A certificate answers identity, purity and net content as three separate questions, each with the method that produced it and the date it was run — how to read one covers what each field does and does not cover. For Bronchogen that means a mass spectrum landing on 446.5 g/mol for C18H30N4O9, the figure published against PubChem CID 11690869.
The certificate below belongs to one lot, and its number matches the one printed on the vial you receive. A real report for a different batch is still the wrong report.
| Size | Lot | Identity method | Purity | Test date |
|---|---|---|---|---|
| 20mg | Pending verification | Pending verification | Pending verification | Pending verification |
No lot documentation is published for Bronchogen yet. Rather than display a placeholder certificate, this record shows the gap until each field has been verified against the lot in hand. The certificate index lists every lot the moment its report clears.

Where the FDA stands on Bronchogen
The FDA has not approved this compound for anything, and nothing in this catalogue is a medicine. Where a compound stands legally depends on what it is, what form it is in, what it is being used for and which country you are in, and it changes over time, so the status shown here carries the date it was last checked.
Status verified 2026-08-25. Regulatory positions move; check the primary source before relying on any summary, including this one.
It is sold here as laboratory material under the research-use restriction that closes this page, which is not an approval, and not a statement that the compound is safe, effective or right for any purpose.
Bronchogen research: what the published studies examine
Status: No FDA-approved application. This compound is sold as laboratory material. Where research on it has been published, it sits at the animal, cell or early-human stage, and this record does not summarise what it found. A supplier is not a neutral judge of evidence about its own catalogue.
Bronchogen is the lung-associated member of the series, described in the primary literature as a tetrapeptide. Vendor material commonly gives the sequence as Ala-Glu-Asp-Leu; that specific assignment is not confirmable from the indexed abstracts, so it is not asserted here. The originating group proposes that these peptides act epigenetically, entering cells and binding directly to specific DNA sequences to modulate transcription of tissue-relevant genes, with molecular docking used as the supporting method.
That is a hypothesis about a mechanism, not a demonstrated pathway, and it has not been independently confirmed outside the groups that advanced it. The series was developed at the St Petersburg Institute of Bioregulation and Gerontology, and the design premise is tissue specificity: each short peptide is claimed to act on the organ its parent extract came from. That premise rests principally on explant-outgrowth assays from the same group.
| Reported observation | Model | Source |
|---|---|---|
| In rats with chronic obstructive pulmonary disease modelled by 60 days of intermittent nitrogen dioxide exposure, one month of tetrapeptide Bronchogen was associated with reduced bronchial epithelial remodelling — less goblet cell hyperplasia, squamous metaplasia, lymphocytic infiltration and emphysema, with restoration of ciliated cells — alongside increased secretory IgA and normalised cell composition and cytokine profile in bronchoalveolar space. | rat chronic obstructive pulmonary disease model induced by nitrogen dioxide exposure | Kuzubova and colleagues, Modulating effect of peptide therapy on the morphofunctional state of bronchial epithelium in rats with obstructive lung pathology, Bulletin of Experimental Biology and Medicine (2015)From the Research Institute of Pulmonology at St Petersburg State Medical University — adjacent to, but not the same as, the originating institute. |
| Synthetic peptides cardiogen, bronchogen, prostamax and pancragen were applied to organotypic explant cultures from heart, lung, prostate and pancreas of young (3-week) and aged (18-month) rats. At 0.05 ng/ml each stimulated explant outgrowth in its corresponding tissue relative to control across all groups — the tissue-specificity claim the series is built on. | organotypic explant culture, young and aged rat tissue | Zakutskii and colleagues, The tissue-specific effect of synthetic peptides-biologic regulators in organotypic tissue culture in young and old rats, Advances in Gerontology (2006)Published in Russian with an English abstract. Explant outgrowth in culture is a long way from a tissue effect in an animal. |
Open questions. The COPD model above is the most substantial single result in this series: a defined injury model, histological endpoints and immunological markers rather than explant outgrowth alone. It is still one study, in rats, from a single research network, and it has not been independently replicated. Two limitations apply to every compound in this series and are worth stating plainly rather than once at the bottom of a catalogue.
First, provenance: the great majority of primary work comes from one institute and its collaborators, much of it published in Russian, and independent replication outside that network is scarce. That is a limit on how confidently the findings can be read, not an allegation about them. Second, the assays: explant outgrowth in organotypic culture and gene-expression shifts in cultured cells are the dominant endpoints, and neither establishes what a compound does in an intact animal, let alone a person.
The proposed epigenetic mechanism — short peptides entering the nucleus and binding DNA directly — is supported largely by molecular docking, which is a computational prediction rather than a measurement.
Each row above describes an observation in the stated model. None of it describes what Bronchogen would do in a person or an animal outside that model, and none of it is a recommendation to use it for anything.
