Kisspeptin is a naturally occurring peptide (and its analogues, like kisspeptin-10) central to reproductive hormone control. It's under active research; therapeutic use is investigational.
How it works
It sits upstream of GnRH — kisspeptin neurons stimulate GnRH release, which then drives LH/FSH. It's essentially a master regulator of the reproductive axis, and people lacking kisspeptin signaling fail to go through puberty normally.
The evidence
There's strong basic-science and growing clinical research interest — in fertility (it tends to drive a predominantly LH response), PCOS, and even links to metabolism. It's a legitimate research target, but analogues are investigational, not approved therapies.
Safety
Studied under research conditions; as an investigational compound its broad safety profile in self-directed use isn't established. Reproductive-axis manipulation is very individual and a clinician matter.
FAQ
QHow is it different from gonadorelin?
Kisspeptin acts one step upstream (stimulating GnRH release); gonadorelin is GnRH acting on the pituitary. Kisspeptin often gives a more LH-weighted response.
QIs it approved?
No — investigational, under active research.
