KISS Peptide

Kisspeptin is a signaling peptide that sits at the top of the reproductive hormone chain. Kisspeptin binds to receptors in the hypothalamus and triggers: GnRH release → LH and FSH release → testosterone or estrogen production. It doesn’t directly raise testosterone - it tells the brain to start the cascade. Why researchers use it Hypogonadism secondary Especially when: low LH low testosterone stress suppression aging decline. It can restart signaling without shutting down natural production like TRT does.
