How Kisspeptin works, and what the research shows.
Kisspeptin is an upstream regulator of GnRH (gonadotropin-releasing hormone).
It naturally stimulates testosterone and estrogen production through the body's own pathways, enhancing desire through hormonal optimization.
Human physiology studies show kisspeptin infusion stimulates LH pulses and downstream testosterone in men, and research groups (notably Dhillo and colleagues in the UK) have run controlled human studies exploring its role in reproductive hormones and sexual desire, including brain-imaging trials in hypoactive sexual desire.
No kisspeptin product is FDA-approved; clinical use is investigational and physician-directed.
