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
