Kisspeptin-10- 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.
- Kisspeptin-10 is the biologically active C-terminal decapeptide of kisspeptin, an endogenous regulator of the reproductive axis. It acts upstream of GnRH to potently stimulate LH and testosterone release, and plays a key role in sexual arousal and libido.
- Half-Life
- ~5–10 minutes but metabolite (CPG) effects last hours
- ~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development
- Admin Route
- Oral, Sublingual, Intranasal
- SubQ, IV
