Bronchogen

What is it?

Bronchogen is a Khavinson tetrapeptide (Ala-Asp-Glu-Leu) targeting bronchial epithelium — part of the respiratory corner of the Khavinson short-peptide bioregulator family, alongside Chonluten. Site tier is Emerging (7 studies, 0 human).

What does it do in my body?

Claimed mechanism: like the rest of the Khavinson family, Bronchogen is proposed to modulate gene expression in a tissue-specific way — here, in bronchial epithelial cells, supporting structural and functional maintenance of the airway lining.

Is it dangerous? What are the side effects?

No serious AEs are documented for Bronchogen specifically (no human data exists to report from). The family-wide reported profile in the Russian literature is mild and uncommon: occasional injection-site reactions, transient mild headache early in a cycle.

The real risk isn’t the molecule — it’s the supply chain. Khavinson-family peptides are the dominant gray-market counterfeit category in the peptide space. Third-party COA verification matters more here than for almost any other peptide class.

Regulatory status: Bronchogen is research_only in the US — not FDA-approved for human use, sold as a research compound, not eligible for compounding. It is not a controlled substance. Unlike Thymalin, Bronchogen holds no clinical-use approval anywhere.

Part 1 — How to reconstitute it

What's used: bacteriostatic water (sterile, preserved water the powder is mixed with) and a separate, larger reconstitution syringe used only for mixing — not the small syringe used for administration.

The exact bacteriostatic-water volume and resulting concentration for Bronchogen are covered in the dosing notes and the deeper-science view. The right volume depends on the vial size.

How it's mixed

• The vial is tilted and the bacteriostatic water is added slowly down the inside glass wall — not squirted straight onto the powder.
• It is swirled gently to dissolve. It is never shaken — shaking can damage the peptide.
• The reconstituted vial is stored refrigerated and out of light.
• Reconstituted peptides are commonly used within a few weeks, inside the beyond-use window the source specifies — that window varies by peptide.

The free reconstitution calculator does the concentration math for any vial size and water volume, including the equivalent units on an insulin syringe.

Part 2 — Typical dosing

Educational context only — talk to a licensed medical provider before any protocol. What follows describes the doses and schedules most commonly reported in the research and by practitioners, shared so you can have an informed conversation. These compounds are sold for research use only, are not FDA-approved drugs, and this is not medical advice.

Administration as reported. Reported practice is subcutaneous administration (into the fat just under the skin) using a 0.3 mL U-100 insulin syringe, with sites rotated.

Educational purposes only — this reflects what the Russian-school protocol convention and the peptide community actually use, stated plainly; it is not medical advice.

There is no Western-validated dosing protocol for Bronchogen — the evidence base is animal-only. What exists is the Khavinson-school cycle pattern shared across the family:

• Cycle structure: a short course — typically 10–20 consecutive days — followed by a long rest, repeated 2–3 times per year.
• Dose: as a synthetic short tetrapeptide, community subcutaneous dosing converges around ~100–200 mcg/day over the cycle; no Bronchogen-specific human dose-finding data exists.
• Storage: lyophilized powder is stable cold; once reconstituted with bacteriostatic water, refrigerate and use within roughly 28 days.

Treat every number above as community/Russian-protocol convergence, not validated dosing.

Turning milligrams into syringe units. On a U-100 syringe, 100 units = 1 mL, so 1 unit = 0.01 mL. At a concentration of C mg/mL, a dose of D mg = D ÷ C mL = (D ÷ C) × 100 units. Example: at 5 mg/mL, a 0.5 mg dose = 0.1 mL = 10 units. The exact units depend on the vial's mg and the water volume used.

What should I avoid combining — and what's synergistic?

Bronchogen doesn't have a dedicated stacking protocol in our notes — the interactions that matter most are in the safety section above. For how people combine it with other peptides, the deeper-science view has the full detail.
