Description
Bronchogen 20mg from Certified Peptides is 20mg of Bronchogen in a sealed glass vial. Bronchogen is a tetrapeptide bioregulator. It’s intended for lab research only.
About Bronchogen
Bronchogen is the tetrapeptide Ala-Glu-Asp-Leu, one of the short peptides linked in Khavinson’s program to the bronchial epithelium, the lining of the airways.
It comes from the bioregulator program led by Vladimir Khavinson at the St. Petersburg Institute of Bioregulation and Gerontology, which proposed that very short peptides can bind DNA and switch particular genes on or off in specific tissues.
How Bronchogen works
Khavinson’s group proposes that short peptides like this one enter the cell nucleus and bind specific DNA sequences, changing how tightly the chromatin is packed in airway lining cells. Looser chromatin lets nearby genes switch on.
That model is still debated. What the published papers actually report is a change in gene and protein expression in cultured cells, and the mechanism behind it hasn’t been confirmed by independent labs.

What the research says about Bronchogen
Russian studies report effects on gene expression in bronchial epithelial cells and on lung inflammation in rats.
Independent replication outside Russia is limited, so it’s best treated as an early-stage research peptide.
The primary literature is on PubMed. Here’s a search for Bronchogen studies to start from.
Bronchogen 20mg purity and lab testing
Every batch of Bronchogen 20mg is made in the USA and checked by an independent U.S. lab for three things: that it’s the right compound, that the amount matches the label and that purity is 99% or better by HPLC.
You don’t have to take our word for it. The certificate of analysis for the current batch is in the image gallery at the top of this page, next to the product photo, and it shows the test date and the results.
Purity isn’t the whole story, so batches are screened for endotoxins, heavy metals and sterility too. Write the batch number from the label into your notes so you can match results to the paperwork later.
Bronchogen 20mg reconstitution and concentration
The amount of liquid you add sets the concentration. For a vial holding 20mg:
- 1mL of bacteriostatic water gives 20mg/mL
- 2mL of bacteriostatic water gives 10mg/mL
- 3mL of bacteriostatic water gives 6.67mg/mL
Pick the volume that keeps your own calculations simple, then write the concentration and the mixing date on the label. The vial itself holds 3mL, so that’s the upper limit.
Use sterile bacteriostatic water, like our 10mL bacteriostatic water. Let the vial reach room temperature, run the water slowly down the inside of the glass, then roll the vial gently until the powder dissolves. Don’t shake it. Shaking can shear peptide chains.
How to store Bronchogen 20mg
Freeze-dried Bronchogen 20mg handles room temperature fine during shipping, but for anything longer keep it in a freezer at -20°C, away from light. Once mixed, keep it in the fridge at 2 to 8°C and use it within about four weeks.
Vials are small and easy to knock over or misplace. Our 6 vial and 10 vial containers keep a whole study’s worth together.
How many Bronchogen 20mg vials do you need?
Work out the total amount before you order. Add up what each arm of the study uses across every time point, then divide by 20mg. Round up by one vial so a spoiled sample or a repeat run doesn’t stall the project.
Only reconstitute what you’ll use in the next few weeks. Sealed vials stay stable in the freezer, while a mixed vial should be finished within about 28 days.
Keep vials from one batch together in a study where you can. The batch number on the label ties each result back to its certificate of analysis.
