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 you'll need: bacteriostatic water (sterile, preserved water you mix the powder with) and a separate, larger reconstitution syringe just for mixing — not the small syringe you inject with.

The exact bacteriostatic-water volume and resulting concentration for Bronchogen are covered in the dosing notes and the deeper-science view. Confirm the right volume for your vial before mixing.

How to mix it

• Tilt the vial and let the bacteriostatic water run slowly down the inside glass wall — never squirt it straight onto the powder.
• Swirl gently to dissolve. Never shake — shaking can damage the peptide.
• Store the reconstituted vial refrigerated and out of light.
• Use it within the beyond-use window your source specifies — reconstituted peptides are commonly used within a few weeks; confirm the window for your specific peptide.

Part 2 — Typical dosing

Talk to your medical provider before starting any protocol. That said, here are the doses most people commonly use — shared for educational purposes so you can have an informed conversation. These peptides are sold for research use only and are not FDA-approved drugs, and this isn't medical advice.

The syringe. Use a 0.3 mL U-100 insulin syringe — it's sized for these small subcutaneous doses. Inject subcutaneously (into the fat just under the skin) and rotate injection sites.

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. Your exact units depend on your own vial's mg and how much bacteriostatic water you added — use the same concentration you mixed above.

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.
