Growth Hormone Secretagogues

Mechanism

Kisspeptin-10 (KP-10) is the 10-amino-acid C-terminal fragment of kisspeptin (the KISS1 gene product, also called metastin) that retains full biological activity. It is an investigational signaling peptide that sits at the top of the reproductive axis and is studied for fertility, hypogonadism, and as a diagnostic challenge. It is not FDA-approved.

Kisspeptin-10 regulates glycosaminoglycan and decorin content in human cardiac fibroblast cultures
Radwańska P, Olkiewicz M, Piera L, Drobnik J. · Pharmacological reports : PR (2026) ·

Background Cardiac fibroblasts play a key role in extracellular matrix (ECM) remodelling through the synthesis of glycosaminoglycans and proteoglycans (PGs), such as decorin; however, the effects of kisspeptin-10 (KiSS-10) on these components in the heart remain unknown.

Relationship between kisspeptin-10, neurokinin B and dynorphin A in the course of normal and delayed puberty in ewes
Szysiak N, Kosior-Korzecka U, Greguła-Kania M, Patkowski K, Fila M, Junkuszew A. · Journal of veterinary research (2026) ·

Introduction Kisspeptin (KiSS), neurokinin B (NKB) and dynorphin A (Dyn A) participate in the neuroendocrine regulation of reproductive system development and functioning; however, their roles in the onset of sexual maturity and pathomechanism of delayed puberty have not yet been fully elucidated.

Kisspeptin-10 attenuates pulmonary arterial hypertension via restoration of mitochondrial function in pulmonary artery smooth muscle cells
Huang S, Chen Z, Gong W, Song Y, Ding W, Zhang L, Li J. · Neuropeptides (2026) · animal

Mitochondrial dysfunction and dysregulated mitophagy in pulmonary artery smooth muscle cells (PASMCs) critically drive pulmonary arterial hypertension (PAH). Here we show that Kisspeptin-10, acting via its receptor GPR54, markedly attenuates PAH in the SU5416/hypoxia mouse model.
