What Is It?
Kisspeptin is a peptide produced in the hypothalamus that plays a central role in signaling the release of gonadotropin-releasing hormone (GnRH), which in turn drives the release of LH and FSH from the pituitary. In laboratory and early clinical research, kisspeptin analogs have been evaluated for effects on hypothalamic-pituitary-gonadal axis signaling and sexual response. In the United States, kisspeptin is dispensed as a compounded prescription and is not FDA-approved. Some providers use it as part of a broader plan supporting hormone-related concerns, libido, or fertility-adjacent goals in eligible adults under monitoring.
