Immune Modulator

Bronchogen

Also known as: AEDL, Ala-Glu-Asp-Leu, T-33, lung peptide bioregulator

Research use only · not FDA-approved research only

Synthetic short-chain tetrapeptide bioregulator (Ala-Glu-Asp-Leu, AEDL) from the Khavinson family of tissue-specific peptides, developed by Vladimir Khavinson and colleagues at the St. Petersburg Institute of Bioregulation and Gerontology and designed from amino-acid analysis of bronchial-mucosa peptide extracts. It is proposed to act epigenetically, penetrating cells and binding DNA to modulate tissue-specific gene expression and protein synthesis in bronchial epithelium and lung tissue. Evidence is almost entirely preclinical and from Russian-language sources; no controlled human clinical trials meeting international standards have been published. It is not FDA-approved or FDA-evaluated and is sold as a grey-market research compound.

Prices observed from public storefronts (last 24h), normalized to $/mg. "Evidence" is Merit's 0–100 Merit Score, derived only from observable verification evidence (methodology on /about); "Purity" is the latest independent COA. Some buy links are affiliate links — Merit may earn a commission at no extra cost to you, and where a vendor offers one, the code shown gets you a discount at their checkout. Affiliate status never affects price data, ranking, or the Merit Score (full policy on /disclosure). Research use only.
