Cardiogen is a four-amino-acid compound designed to act on heart tissue and sold as a laboratory chemical rather than as a medicine. Its supporting record is small, one-sided, and comes almost entirely from the institute that created it. None of it involves people. The most concrete documented harms belong to the unlicensed supply channel rather than the molecule. (Full Review)
| Marker | Target | Why |
|---|---|---|
| High-sensitivity C-reactive protein | Below 0.5 mg/L | Tracks the cell-ageing inflammation the peptide targets, and rises with contamination reactions |
| Interleukin-6 | Below 1.5 pg/mL | Second inflammatory signal, less affected by acute infection |
| N-terminal pro-B-type natriuretic peptide | Below 50 pg/mL under age 65 | Reflects heart wall stretch, the closest routine proxy for the claimed cardiac benefit |
| High-sensitivity cardiac troponin T | Below 5 ng/L | Detects ongoing myocardial injury and any new insult during a course |
| Apolipoprotein B | Below 80 mg/dL | Carries the actual artery-narrowing burden that no peptide claim addresses |
| Estimated glomerular filtration rate | Above 90 mL/min/1.73 m² | Clearance capacity for injected impurities and diluent |
| Alanine aminotransferase | Below 25 U/L in men, below 20 U/L in women | Organ safety screen for any unapproved injected compound |
| Absolute eosinophil count | Below 200 cells/µL | Early signal of hypersensitivity to synthesis by-products |
| Seated blood pressure | 110-120 / 70-75 mmHg | Cheapest cardiovascular endpoint available and a check on unexpected circulatory change |
| Resting heart rate | 50-65 bpm | Sensitive to inflammatory and febrile reactions before symptoms appear |
Cadence: Baseline before a first course, repeat at 4 weeks, at the end of a course, then every 6 to 12 months, with an unscheduled panel after any febrile or injection-site reaction.
