Kisspeptin-10 activates the KISS1R (GPR54) receptor on hypothalamic GnRH neurons, stimulating GnRH release and thereby downstream LH and FSH secretion.
Investigational: research into hypothalamic amenorrhea, infertility, safer ovulation triggering in IVF, and studies of sexual/emotional brain responses; not an approved therapy.
Physiologic, upstream stimulation of the reproductive axis; in research it triggers ovulation with potentially lower hyperstimulation risk; interest in libido/mood research.
Purely experimental with limited human safety data; very short half-life; effects can desensitize with continuous dosing; research-chemical supply is unregulated and quality is uncertain.
Enthusiast interest for libido and fertility support, but users acknowledge it is experimental with thin real-world data.
NOT FDA-approved for any use; investigational only and sold as a research chemical, not a legal therapeutic.
