Kisspeptin (10mg)
Kisspeptin is a neuropeptide produced by hypothalamic neurons, identified in research as the principal upstream regulator of GnRH release and the hypothalamic-pituitary-gonadal axis.
About Kisspeptin
Kisspeptin is a neuropeptide derived from the KISS1 gene, predominantly produced by hypothalamic neurons. It is identified in research as the principal upstream activator of gonadotropin-releasing hormone (GnRH) neurons and, by extension, the entire hypothalamic-pituitary-gonadal (HPG) axis. Its discovery substantially reshaped understanding of reproductive endocrinology.
Mechanism in Research Literature
Research on kisspeptin has documented:
- Binding to KISS1R (also known as GPR54) on GnRH neurons
- Triggering pulsatile GnRH release from the hypothalamus
- Downstream stimulation of pituitary LH and FSH secretion
- Subsequent gonadal hormone production via standard HPG axis cascade
- Role as the convergent signal for nutritional, metabolic, and circadian inputs onto the HPG axis
Research Context
Kisspeptin has been investigated in studies exploring:
- Reproductive endocrinology and HPG axis regulation
- Puberty onset and timing research
- Fertility and ovulation research in both sexes
- Metabolic and energy-balance integration with reproductive function
- Comparative pharmacology of kisspeptin analogs vs. GnRH agonists
Related Research Peptides
Kisspeptin appears in literature alongside HCG (downstream LH-receptor activation), PT-141 (central libido pathway, distinct receptor), and broader hormone-axis research peptides.
