Kisspeptin 10MG
Endogenous decapeptide fragment that stimulates GnRH and activates the HPG axis. Potential benefits include supporting diagnostics and research in fertility, hypogonadism, and libido. Early human studies show acute LH/testosterone rises. Longer‑term therapeutic effects are still under study.
Kisspeptin-10 (KP-10) Research & Chemical Profile
Description
Kisspeptin-10 (KP-10) is a decapeptide fragment of the KISS1 gene product that acts as an endogenous ligand at the kisspeptin receptor (KISS1R/GPR54). KP-10 potently stimulates hypothalamic gonadotropin-releasing hormone (GnRH) secretion, thereby activating the hypothalamic–pituitary–gonadal (HPG) axis. The peptide has been investigated for roles in reproductive endocrinology, puberty initiation, fertility modulation, and tumor biology.

Primary Research Focus
• Reproductive axis activation: KP-10 stimulates GnRH release, increasing LH and testosterone secretion in humans and animal models.
• Puberty and fertility research: central in timing of puberty and regulation of ovulation/spermatogenesis.
• Oncology/angiogenesis: KP-10 has been reported to inhibit VEGF-driven angiogenesis and tumor growth in preclinical models.
• Neuroendocrine signaling: integrates with neurokinin B and dynorphin neurons in the arcuate nucleus to regulate GnRH pulsatility.Safety / Limitations
• Human studies show acute endocrine responses, but long-term safety/efficacy data are limited.
• Effects can be dose- and route-dependent; tachyphylaxis has been described with continuous infusion.
• Research Use Only; not approved for diagnosis, treatment, or prevention of disease.Key Publications / References
