Kisspeptin-10

Overview

Kisspeptin-10 is the 10-amino-acid C-terminal fragment of kisspeptin, a KISS1-gene-derived neuropeptide that activates the kisspeptin receptor (KISS1R, formerly GPR54) on GnRH neurons. By stimulating GnRH release, it triggers downstream secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), making it a key upstream regulator of the reproductive axis. Kisspeptin is an active area of human research — controlled studies (mostly using kisspeptin-54, with kisspeptin-10 used in some protocols) have probed its effects on reproductive hormones, fertility-related signaling, and, more recently, sexual/brain responses in people with low sexual desire. No kisspeptin product is FDA-approved, and most human work is early-phase or investigational. Marketed claims beyond these research contexts should be treated as unproven.

Commonly Reported Uses

These are uses commonly discussed or marketed by users and vendors — not a list of proven or approved benefits, and not a recommendation.

• Stimulating LH/FSH and the reproductive axis (research/diagnostic context; not an approved therapy)
• Investigational support for low sexual desire / arousal (early human studies, mostly kisspeptin-54; not approved)
• Fertility and hypothalamic-pituitary-gonadal research applications (investigational)

What to Track

Data points you and your clinician might monitor. For observation only — not a diagnostic protocol.

• Labs — LH and FSH (the most direct, mechanistically expected response to kisspeptin)
• Labs — testosterone (men) or estradiol (women) as downstream sex-steroid readouts if a clinician is monitoring
• Subjective — daily check-ins on libido/arousal and mood (the focus of recent sexual-desire studies)
• Subjective — tolerability (kisspeptin has generally been well tolerated in trials, but watch for any injection-site or systemic effects)
