Kisspeptin
Stimulates natural reproductive hormone production
- Hormone Optimization (LH/FSH stimulation)
Human safety data is extremely limited - most evidence derives from animal studies Effects on long-term reproductive function are unknown Not recommended for use in children or adolescents due to potential effects on pubertal development Pregnant women should avoid kisspeptin due to its role in pregnancy-related hormonal regulation and potential effects on implantation/placental development
Mechanism of Action
Kisspeptin is a neuropeptide that binds to the kisspeptin receptor (GPR54/KISS1R) on GnRH neurons in the hypothalamus, directly stimulating the release of gonadotropin-releasing hormone (GnRH). This GnRH release triggers the pituitary gland to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are essential for gonadal function and reproductive hormone production. Key Pathways: Hypothalamic-pituitary-gonadal (HPG) axis activation via GPR54/KISS1R signaling, GnRH neuron stimulation leading to pulsatile LH/FSH release, Interaction with neurokinin B (NKB) and dynorphin in the KNDy neuron network By activating the HPG axis upstream at the hypothalamic level, kisspeptin can stimulate endogenous testosterone or estrogen production through increased LH secretion. This makes it potentially useful for restoring gonadal function in cases of central hypogonadism or after suppression from exogenous hormone use, as the effect works through the body's natural hormone cascade rather than bypassing it.
