Kisspeptin-10 is a naturally derived signaling peptide and one of the most important experimental regulators of the reproductive hormone axis. It acts upstream of gonadotropin-releasing hormone (GnRH), making it particularly interesting for research into LH, FSH, testosterone, fertility, and reproductive function.
Kisspeptin-10 is the minimal kisspeptin sequence retaining strong biological activity and has been studied directly in human volunteers.
Product Information
Kisspeptin is produced naturally in the body and acts through the KISS1 receptor (KISS1R). Its major biological role is regulating GnRH neurons in the hypothalamus, which then influence pituitary LH and FSH release.
Human studies have shown that Kisspeptin-10 can rapidly increase LH secretion in men, while kisspeptin administration in women can stimulate reproductive hormone signaling in a cycle-dependent manner.
How Does Kisspeptin-10 Work?
Kisspeptin-10 activates KISS1R, stimulating GnRH release and downstream LH/FSH secretion. This makes it a key experimental tool for studying the hypothalamic-pituitary-gonadal axis.
Kisspeptin-10 Benefits
Stimulates LH Release
Kisspeptin-10 produces a strong and rapid LH response in human studies. In healthy men, a 1 μg/kg IV bolus produced the strongest LH response among the tested bolus doses.
Supports Testosterone Research
Because LH stimulates testosterone production in the testes, Kisspeptin-10 has become an important research tool for investigating natural testosterone regulation through the hypothalamic-pituitary-gonadal axis. Continuous kisspeptin infusion has been shown to increase both LH and testosterone in men.
Fertility and Reproductive Research
Kisspeptin is central to reproductive signaling and has been investigated in hypogonadism, infertility, ovulation, and reproductive disorders. Human research demonstrates that its effects vary according to sex, reproductive status, and hormonal environment.
Sexual-Function Research
More recent human research has explored kisspeptin in men and women with hypoactive sexual desire disorder. Clinical trials have demonstrated changes in sexual-processing brain activity and measures of sexual desire, making the kisspeptin pathway an active area of psychosexual research.
Kisspeptin-10 Side Effects
Clinical studies have generally found kisspeptin to be well tolerated, although headache, dizziness, flushing, fatigue, nausea, and injection-related discomfort have been reported in some study populations. ClinicalTrials.gov data for kisspeptin administration also list headache, dizziness, nausea, and muscle-related complaints among reported adverse events.
Kisspeptin-10 Dosage
Human research with Kisspeptin-10 has used 0.01–3 μg/kg IV bolus doses, with 1 μg/kg producing the strongest LH response in one male study. Continuous infusions of 1.5–4 μg/kg/hour have also been investigated. These are research protocols rather than a standardized consumer dosing schedule.
