Chonluten
What it is
Chonluten is a synthetic short-peptide bioregulator, a tripeptide with the amino acid sequence Glu-Asp-Gly (EDG), also referred to as T-34. It belongs to the Khavinson family of peptide bioregulators characterized at the St. Petersburg Institute of Bioregulation and Gerontology, and it is the defined-sequence synthetic counterpart to Bronchogen, a peptide preparation originally derived from bronchial tissue.
Research context and categorization
Chonluten is grouped under the Khavinson bioregulators, a class of short peptides discussed in the context of tissue-specific gene-expression signaling. Within that family it is categorized as a bronchial or respiratory bioregulator, meaning research discussion centers on lung and airway tissue.
In neutral terms, Chonluten is studied in the context of how short peptides may influence gene-expression profiles in respiratory epithelial models, and it is commonly discussed in relation to inflammation, oxidative-stress signaling, and cellular proliferation in airway tissue. Some preclinical and animal-model reports investigate it in relation to mucosal function in respiratory conditions. These uses are investigational only. Chonluten is not FDA-approved, the work sits at the preclinical and in-vitro level, and none of these discussed effects should be read as confirmed, established, or approved benefits.
Status
- Regulatory status: Research-only. Chonluten is not FDA-approved for any indication and is supplied and handled as a laboratory research material. Published work on it sits at the preclinical and investigational level.
- Sport status: Not specifically listed by name on the WADA Prohibited List. However, because it is a peptide not approved by any government regulatory authority for human therapeutic use, it could fall within the S0 Non-Approved Substances catch-all that WADA applies to experimental and unapproved compounds. Athletes should treat its status as unsettled and verify against the current official list.
Reconstitution notes (general)
Chonluten typically ships as a lyophilized (freeze-dried) powder that is reconstituted before laboratory use. Working concentration is a simple ratio: concentration equals the milligrams of peptide in the vial divided by the millilitres of bacteriostatic water added. For example, a 20 mg vial brought up with 2 mL yields 10 mg/mL, and the same vial with 3 mL yields about 6.67 mg/mL. To work out a target concentration or fill volume for any vial size, use the calculator at /pages/tools.
Dilution and handling notes (compound-specific)
Chonluten is commonly sold in 20 mg vials, and a typical reconstitution volume falls in the roughly 2 mL to 3 mL range of bacteriostatic water, which places the working concentration between about 6.67 mg/mL and 10 mg/mL. The volume chosen is mostly a matter of convenience for measuring small research aliquots on a U-100 syringe rather than a solubility limit.
Being a very short tripeptide, Chonluten is highly water-soluble and generally goes into solution readily, producing a clear, colorless liquid without the gelling, clouding, or slow precipitation that larger or more hydrophobic peptides can show when concentrated. Because it dissolves easily, aggressive mixing is unnecessary and counterproductive.
Practical handling is mostly about technique rather than stubborn solubility. Add the water slowly down the inner wall of the vial rather than squirting it directly onto the powder plug, and mix by gently swirling or rolling the vial between the palms rather than shaking, since vigorous agitation whips air into the liquid and causes foaming that makes the fill level harder to read. Let the vial rest for a short period after mixing so any bubbles settle and dissolution completes. Keep the material out of direct light, and if a batch will not be used quickly, dividing it into single-use aliquots avoids repeated freeze-thaw cycles that can degrade peptide material.
Handling and storage
Store the reconstituted vial refrigerated at 2 to 8 degrees Celsius and keep it out of direct light. Wipe the rubber stopper with an alcohol swab before each puncture, and label the vial with the mix date so the age of the solution is always known. Observe the general four-week refrigerated window commonly cited for reconstituted peptide, and discard any vial that turns cloudy or discolored or that shows floaters or particulate.
