Chonluten — EU research guide.

Chonluten is a synthetic tripeptide (Glu-Asp-Gly) from the Khavinson bioregulator series targeting bronchopulmonary tissue broadly, including mucosal and lung-function markers. It is often discussed alongside Bronchogen and Taxorest in Eastern European literature on bronchopulmonary peptide bioregulators, though the three target slightly different aspects of lung tissue.

What is Chonluten?

Chonluten is a synthetic tripeptide (Glu-Asp-Gly) from the Khavinson bioregulator series targeting bronchopulmonary tissue broadly, including mucosal and lung-function markers. It is often discussed alongside Bronchogen and Taxorest in Eastern European literature on bronchopulmonary peptide bioregulators, though the three target slightly different aspects of lung tissue.

What does the research show?

Reported effects center on lung function and mucosal-health markers in claims by the originating research group, summarised in a 2020 review without sample sizes; no primary Chonluten study could be verified. No large independently replicated trials are publicly available as of mid-2026.

EU legal status

Not approved as a medicine anywhere in the EU. Sold by a small number of specialist research vendors for laboratory use only.

⚠ Closely related Khavinson respiratory peptides (Bronchogen, Chonluten, Taxorest) are sometimes used interchangeably in vendor marketing despite different sequences — read the actual product specification, not just the category label.
✓ PeptideCompare monitors Chonluten across EU research suppliers. Verify any vendor's COA and sequence/identity claims directly before ordering — see our COA guide.
EVIDENCE SUMMARY
LIMITED
Bronchopulmonary and stress-protection claims (review only) — A 2020 review by the originating group states that the Glu-Asp-Gly tripeptide (Chonluten) gave higher physical performance under low oxygen pressure and improved standard therapy in patients with chronic bronchitis with an asthmatic component, and that it modulates expression of genes such as c-Fos, HSP70, SOD, COX-2 and TNF-alpha. The review gives no sample sizes and cites earlier Russian work that could not be opened here.
NO HUMAN DATA
No verified primary or independent human data — No primary paper or clinical trial of Chonluten could be opened and no independent replication was found. The review itself calls its COVID-19 suggestion a potential application, not demonstrated efficacy.

Pharmacokinetics

No established human pharmacokinetic data. Published human PK parameters for this compound are not available; reported data are limited to animal models or absent. No curve is shown, to avoid implying data that does not exist.

Potency retained over time

Each line is one storage condition: it starts at 100% and declines as potency is lost. Above the dotted 80% line the material is considered reliable — hover the chart for exact values.
