Gonadorelin
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.
Gonadorelin is the synthetic form of endogenous GnRH (gonadotropin-releasing hormone). It stimulates the pituitary to release LH and FSH, maintaining testicular function and testosterone production. Widely used alongside TRT to prevent testicular atrophy and preserve fertility.

Admin Route
IV, IM
SubQ, Intranasal
Research
Typical Dose
5–10 mL
100 mcg
Frequency
Daily for 10–20 days
Twice daily (every 12 hours)
Key Benefits
  • Promotes neurogenesis and synaptic plasticity
  • Approved for stroke rehabilitation (accelerates recovery)
