Liraglutide
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.
Liraglutide is a long-acting GLP-1 receptor agonist approved for type 2 diabetes (Victoza) and chronic weight management (Saxenda). It reduces appetite, slows gastric emptying, improves insulin secretion, and promotes weight loss of 5–10% in clinical trials.

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
  • Promotes weight loss (5–10% average)
  • Reduces appetite and caloric intake
  • Improves blood glucose control (HbA1c reduction)
  • Reduces cardiovascular events in T2DM (LEADER trial)
  • Slows gastric emptying
  • FDA-approved for T2DM and chronic weight management
  • Cardioprotective effects shown in clinical trials
  • May improve fatty liver (NAFLD/NASH)
