Kisspeptin-10 is a synthetic peptide derived from the naturally occurring kisspeptin protein, which plays a key role in regulating reproductive hormone signaling within the body. Kisspeptin-10 works by stimulating the release of gonadotropin-releasing hormone (GnRH), which in turn influences luteinizing hormone (LH) and follicle-stimulating hormone (FSH), both essential for hormonal balance and reproductive function. Commonly studied in the context of hormone optimization and fertility support, Kisspeptin-10 may help support natural testosterone production, reproductive health, and overall endocrine function.
