Gonadorelin
Summary
Noopept is a potent dipeptide-derived nootropic from Russia, structurally related to piracetam but estimated to be 1,000 times more potent by mass. It enhances memory consolidation, learning, and recall while providing neuroprotection via BDNF and NGF upregulation.
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.
Half-Life
~5–10 minutes but metabolite (CPG) effects last hours
~2–4 minutes (extremely short); pulsatile dosing required to avoid desensitization
Admin Route
Oral, Sublingual, Intranasal
SubQ, Intranasal
Research
Typical Dose
10–30 mg
100 mcg
Frequency
1–2x daily
Twice daily (every 12 hours)
Key Benefits
  • Enhances memory formation and recall
  • Improves learning speed and cognitive processing
  • Neuroprotective via BDNF/NGF upregulation
  • Anxiolytic at low-to-moderate doses
  • Improves verbal fluency and information processing
  • Antioxidant (reduces oxidative damage in neurons)
  • May improve cognitive symptoms of mild cognitive impairment
  • Maintains testicular size during TRT
