Chonluten is a three-amino-acid peptide sold as the lung member of a family of organ-targeted compounds developed in Russian laboratories. Nothing has been measured in a living person, and the airway claim driving its marketing rests on a different, related peptide. With no approval, safety record or oversight, the hazard is the product itself. (Full Review)
| Marker | Target | Why |
|---|---|---|
| High-sensitivity C-reactive protein | Below 0.5 mg/L | Primary systemic inflammation readout |
| Interleukin-6 | Below 1.5 pg/mL | Tests the cytokine suppressed in cell studies |
| Full blood count with differential | Neutrophil-to-lymphocyte ratio 1.0–2.0 | Detects blunted immune reserve |
| Absolute eosinophil count | Below 300 cells/µL | Marks allergic airway inflammation |
| Spirometry (FEV1/FVC) | Ratio above 0.80, FEV1 above 90% predicted | Only objective measure of the claimed outcome |
| Fractional exhaled nitric oxide | Below 20 ppb | Non-invasive airway inflammation marker |
| Resting oxygen saturation | 96–99% | Cheap daily gauge of gas exchange |
| Salivary secretory immunoglobulin A | Track change from own baseline | Mucosal immune defense |
| Comprehensive metabolic panel | Within laboratory reference range | Baseline organ safety; no toxicology data |
Cadence: Baseline before a first course, again at its end, again 8 weeks after stopping, then every 6–12 months if courses continue.
