Kisspeptin-10 is the biologically active decapeptide fragment of the KISS1 gene product, functioning as the endogenous ligand for the KISS1 receptor (KISS1R, also known as GPR54). Kisspeptin signaling sits upstream of gonadotropin-releasing hormone (GnRH) neurons in the hypothalamus, positioning it as a key regulatory node within the hypothalamic-pituitary-gonadal (HPG) axis. Research has identified kisspeptin as a critical mediator connecting metabolic, circadian, and steroid hormone feedback signals to pulsatile GnRH release.

Preclinical research has extensively characterized kisspeptin’s stimulatory effect on GnRH neuron firing and the subsequent downstream release of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) from the anterior pituitary. Studies have examined its role in the onset of puberty, its involvement in the preovulatory LH surge, and its interactions with metabolic signals such as leptin, positioning kisspeptin as a research focus in reproductive endocrinology and fertility science. Research models have also investigated KISS1R signaling pathways, receptor desensitization kinetics, and species-specific variations in kisspeptin isoform activity.

This 5mg lyophilized format is suited for smaller research protocols, receptor binding studies, and initial dose-response investigations examining HPG axis activation.

Kisspeptin-10 is a standard reference compound in reproductive neuroendocrinology, GnRH pulsatility research, and HPG axis pharmacology, valued for its well-characterized upstream regulatory role.
