What is kisspeptin? It is a natural signal peptide that sits at the very top of the reproductive hormone chain. It acts on GnRH neurons in the brain, the cells that start the signal for the rest of that chain. Kisspeptin-10 is the short, ten amino acid piece that labs study most.

How does kisspeptin work?
Think of the reproductive hormone system as a line of dominoes. Kisspeptin tips the first one. It acts on GnRH neurons, which then signal the pituitary gland, which then releases hormones such as luteinizing hormone (LH). Researchers call this line the hypothalamic-pituitary-gonadal axis, or HPG axis.
Kisspeptin-10 vs kisspeptin-54
Kisspeptin comes in more than one length. The two you will read about most are kisspeptin-54, the longer form, and kisspeptin-10, the short ten amino acid piece. Studies do not always use the same one, so it helps to know which form each paper tested.
Study | Form tested | Who was studied | What it reported |
Kisspeptin-54 | Men | Stimulated the HPG axis | |
Kisspeptin-10 | Men | A potent LH stimulator that raised LH pulse frequency | |
Kisspeptin-10 | Men with type 2 diabetes | Later follow-up work |
Only the last two tested the short form. If a page quotes the 2005 study to talk about Kisspeptin-10, it is mixing up the two forms.
Is kisspeptin FDA approved?
No. Kisspeptin-10 is not an approved medicine. The studies above measured hormone signals under study conditions. They are not a guide for any person, and this page gives no doses or directions. Research vials are for laboratory research use only.
