Cardiogen vs Testagen
Side-by-side comparison of key properties, dosing, and research.
- Summary
- Cardiogen is a tetrapeptide bioregulator (Ala-Glu-Asp-Arg) developed by Professor Vladimir Khavinson. It is a tissue-specific bioregulator for the heart and myocardium, designed to normalize cardiomyocyte function and support cardiac tissue regeneration. Research has demonstrated cardioprotective effects, improved cardiac rhythm, and benefits in recovery from ischemic injury.
- Testagen is a tetrapeptide bioregulator (Lys-Glu-Asp-Gly) developed by Professor Vladimir Khavinson, tissue-specific for the testes. It supports Leydig cell function, normalization of testosterone biosynthesis, and spermatogenic activity. Testagen is used in men's health protocols for age-related testosterone decline, male fertility support, and testicular anti-aging.
- Half-Life
- Short (minutes); gene-regulatory effects persist longer

- Key Benefits
- Cardioprotective effects on myocardial tissue
- Normalization of cardiomyocyte protein synthesis
- May improve cardiac rhythm and conduction
- Support for recovery from ischemic cardiac events
- Anti-aging effects on heart tissue
- Potential reduction in cardiac fibrosis
- Often combined with Epithalon for comprehensive cardiovascular longevity support
- Supports endogenous testosterone synthesis via Leydig cell normalization
- Promotes spermatogenesis and sperm quality
- Anti-aging effects on testicular tissue
- May attenuate age-related testosterone decline
- Mechanistically distinct from TRT — does not suppress HPG axis
- Useful adjunct to Gonadorelin and Kisspeptin-10 in male hormonal protocols
- Supports male fertility without exogenous hormone replacement
- Side Effects
- Generally well tolerated in available research
- Mild injection site reactions
- No significant adverse cardiovascular events reported at standard doses
