Kisspeptin-10 is a 10-amino-acid neuropeptide that plays a central role in regulating the reproductive hormone axis. It is the smallest active fragment of the kisspeptin family and potently stimulates GnRH release, influencing testosterone, LH, and FSH levels. Researched for libido, fertility, and reproductive endocrinology.
Category: Hormonal & Reproductive. Evidence rating: B (meaningful human data).
Clinical status: Phase II clinical trials for reproductive disorders. Active academic research programs.
Stimulates GnRH (gonadotropin-releasing hormone) release from hypothalamic neurons by binding to the KISS1R (GPR54) receptor. This triggers the hypothalamic-pituitary-gonadal axis, increasing LH and FSH secretion, which in turn stimulates gonadal hormone production.
Safety considerations: Well-tolerated in clinical studies with IV and SC administration; Short-acting (minutes), limiting side effect duration; No serious adverse events reported in clinical trials.

Kisspeptin acts upstream of GnRH — it stimulates the release of GnRH, which then triggers LH/FSH. Gonadorelin IS synthetic GnRH. Kisspeptin provides more physiological stimulation of the entire HPG axis.
Kisspeptin-10 is a neuropeptide researched for its central role in regulating the reproductive hormone axis and its potential effects on libido and sexual function.
