What is Kisspeptin?
Kisspeptin (originally known as Metastin) is a naturally occurring neuropeptide produced in the hypothalamus. It is the product of the KISS1 gene. While originally discovered for its ability to suppress tumor metastasis, researchers later identified Kisspeptin as the absolute master regulator of the human reproductive system and puberty. The active, highly potent fragment commonly used in research is Kisspeptin-10.
How does Kisspeptin work?
Kisspeptin binds directly to G-protein coupled receptors (GPR54, also known as KISS1R) on Gonadotropin-Releasing Hormone (GnRH) neurons in the brain. This binding stimulates the release of GnRH, which in turn triggers the pituitary gland to secrete Luteinizing Hormone (LH) and Follicle-Stimulating Hormone (FSH). These hormones then stimulate the testes to produce testosterone in men, or the ovaries to produce estrogen and trigger ovulation in women.
Primary Documented Uses
- Stimulating natural testosterone production in men
- Treating hypothalamic amenorrhea and restoring ovulation in women
- Addressing low libido and psychogenic sexual dysfunction
- Supporting fertility and hormonal balance without pituitary suppression
Research Summary
Human clinical trials show that Kisspeptin-10 administration safely and rapidly increases LH, FSH, and testosterone levels in men without the testicular shrinkage or fertility suppression associated with direct testosterone replacement therapy (TRT). Research also indicates that Kisspeptin modulates brain networks associated with sexual attraction, mood, and romantic love, showing promise as a treatment for psychogenic sexual dysfunction.
Legal and Regulatory Status
Kisspeptin is not FDA-approved for general human clinical use. It is studied in clinical trials for fertility and endocrine disorders. It is legally compounded by some specialized compounding pharmacies under prescription and is widely available as a laboratory research chemical.
