Testagen- Summary
- Cerebrolysin is a porcine brain-derived neuropeptide complex that mimics the action of endogenous neurotrophic factors (BDNF, NGF, GDNF, NT-3). It promotes neurogenesis, neuroprotection, and synaptic plasticity, and is approved in many countries for stroke, traumatic brain injury, and Alzheimer's disease.
- 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
- Variable for the complex; individual peptide fractions: minutes to hours
- Short (minutes); sustained gene-regulatory effects
- Admin Route

- Daily for 10–30 days
- Key Benefits
- Promotes neurogenesis and synaptic plasticity
- Approved for stroke rehabilitation (accelerates recovery)
- Alzheimer's disease: slows progression and improves cognition
- Traumatic brain injury recovery
- Enhances memory and executive function
- Neuroprotection against oxidative stress and excitotoxicity
- Anti-amyloid and anti-tau effects
- Mood improvement and reduced anxiety
- 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
