Kisspeptin-10
Summary
Humanin is a mitochondria-derived peptide (MDP) encoded in the 16S rRNA region of the mitochondrial genome. It protects neurons and other cells from apoptosis, improves insulin sensitivity, and declines significantly with age. HNG (S14G-Humanin) is a synthetic analog with 1000x greater potency.
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.

Key Benefits
  • Neuroprotection against amyloid-beta toxicity (Alzheimer's relevance)
  • Inhibits cellular apoptosis
  • Improves insulin sensitivity
  • Reduces cardiovascular risk markers
  • Anti-inflammatory effects
  • Correlates with longevity in centenarian studies
  • Protects against ischemic injury
  • Potential cancer cell apoptosis sensitization
  • Potently stimulates LH and testosterone
