Overview
Kisspeptin is a reproductive hormone-signaling peptide that plays a key role in regulating the hypothalamic-pituitary-gonadal axis. It helps stimulate the release of GnRH, which then influences luteinizing hormone and follicle-stimulating hormone. These hormones are involved in testosterone production, ovulation, fertility, and reproductive health. Kisspeptin is commonly researched for hormone optimization, fertility support, puberty regulation, and testosterone-related signaling. Its purpose is not general muscle growth or fat loss, but upstream reproductive hormone communication.
