Research background

About Bronchogen

Bronchogen is a four-residue peptide, Ala-Glu-Asp-Leu (AEDL), one of the short bioregulator peptides from Khavinson's programme. The order of the residues matters: the same four amino acids in another order make a different compound, so check the sequence on the COA, not only the composition.

Its literature comes mainly from that group: gene expression and protein synthesis in bronchial epithelium (Khavinson et al., 2014), the bronchial epithelium in an animal model (Kuzubova et al., 2015) and epigenetic regulation during cell aging (Ashapkin et al., 2015). It sits with the other bioregulator peptides in Longevity & mitochondria.

Bronchogen FAQ

How do I tell Bronchogen from Epithalon and Cortagen?

All three start with Ala-Glu-Asp; Bronchogen ends in leucine, Epithalon in glycine and Cortagen in proline. Bronchogen's molecular weight is 446.5 g/mol, and the MS identity on the COA checks the lot against it.

Why is no frozen-storage period given?

Because none has been supported for this peptide. The storage line gives 2–8 °C for unopened material; longer or frozen storage should rest on stability data for your lot.

How to order

Ordering Bronchogen from Medabol

Kit and minimum
Bronchogen is sold by the kit: 10 vials of one specification (20 mg). The minimum is 1 kit per SKU, so an individual buyer can order a single kit and a lab can order many.
Price
Reference prices are listed per kit above, from $136.85. The kits of your whole quote list count together — 5–19 kits are 20% off every kit, and from 20 kits our sales team quotes the price — so Bronchogen adds up with anything else you order; your written quote has the final price.
Documents
Every lot has its own COA with HPLC purity and MS identity; the order ships with the certificate of its lot, and our sales team sends it before you order if you ask.
Shipping
Orders ship from China by international express courier. Shipping from $80 per order; the written quote confirms the exact charge for your destination.
Payment
Nothing is paid on this website. After you send your quote list, a sales representative confirms the amount and shipping on WhatsApp or by email and tells you in that chat how to pay.
Research goal
Listed under Longevity & mitochondria — Mitochondrial peptides, NAD+ and cofactors, and bioregulator peptides.
