Kisspeptin-10 vs Oxytocin

Key differences, research and prices — side by side.

The key difference

Both are hypothalamic peptides involved in reproduction. Kisspeptin sits at the top of the reproductive hormone cascade, triggering LH and FSH release via GnRH neurons. Oxytocin is a nine-amino-acid hormone that controls uterine contractions and milk let-down and is FDA-approved (Pitocin) for labor.

Kisspeptin-10Oxytocin
What it isKisspeptin-10 is the active ten-amino-acid fragment of kisspeptin, a hormone that sits at the top of the reproductive hormone chain.Oxytocin is a nine-amino-acid hormone made in the hypothalamus and released by the pituitary gland.
How it worksIt activates the KISS1 receptor on GnRH neurons, triggering release of the hormones LH and FSH.It acts on oxytocin receptors in the uterus, breast and brain, controlling contractions and milk let-down, and influencing social behavior.
