Kisspeptin is a natural hormone made by neurons in the hypothalamus. It tells your GnRH neurons when to fire, which sets the rhythm for your whole reproductive-hormone system.

Kisspeptin is investigational and not FDA-approved, and safety data in people are limited to small research studies. Possible side effects include redness, pain or swelling where you inject, flushing and headache. Because it acts on reproductive hormones, it is not for use during pregnancy. Tell your clinician if you are pregnant, trying to conceive or breastfeeding, and about any hormone therapy, fertility treatment or other medications. A licensed clinician decides whether it's appropriate for you. See the medical disclaimer.

Kisspeptin is a natural hormone made by neurons in the hypothalamus. It tells your GnRH neurons when to fire, which sets the rhythm for your whole reproductive-hormone system.
GnRH prompts the pituitary to release LH and FSH. Those, in turn, drive testosterone and estrogen. Kisspeptin sits upstream of all of it, which is why scientists find it so interesting.
Small studies at Imperial College London (the Dhillo group) have measured hormone responses and brain activity linked to attraction after kisspeptin. That's research, not proof of benefit, and it isn't FDA-approved. That's why a clinician reviews it with you first.
