Kisspeptin-10 vs Oxytocin
Key differences, research and prices — side by side.
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-10 | Oxytocin | |
|---|---|---|
| What it is | Kisspeptin-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 works | It 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. |
