Summary
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.
VIP is a 28-amino acid neuropeptide with profound anti-inflammatory, vasodilatory, and immunomodulatory effects. It plays a critical role in gut motility, circadian rhythm, and immune tolerance. Used therapeutically for CIRS (Chronic Inflammatory Response Syndrome), MCAS, and inflammatory conditions.
Half-Life
~4 minutes (rapidly degraded); longer-acting analogs like TAK-448 are in development
~2 minutes in plasma (rapidly degraded by peptidases); intranasal delivery may extend local CNS effects

Key Benefits
  • Potently stimulates LH and testosterone
  • Enhances sexual arousal and libido
  • Activates HPG axis — upstream of GnRH
  • May improve fertility in hypogonadotropic hypogonadism
  • Increases brain activation in sexual attraction circuits
  • May restore LH pulsatility in suppressed HPG axis
  • Potent anti-inflammatory for CIRS and mold illness
  • Improves pulmonary hypertension symptoms
  • Regulates gut motility and IBS symptoms
  • Modulates circadian rhythm and sleep quality
  • Reduces mast cell activation (MCAS)
  • Improves cognitive function in neuroinflammatory conditions
  • Vasodilatory — reduces vascular resistance
