Kisspeptin 10mg

GPR54, also called the KISS1 receptor (KISS1R),⁽⁷⁾ has been suggested by researchers to be an important GnRH receptor.⁽¹⁾ They further suggest that Kisspeptin-10 exhibits action by possibly binding to GPR54 receptors, which may activate the reproductive axis by stimulating the release of GnRH and gonadotropin neurons.⁽⁷⁾

Kisspeptin-10 is a 54 amino acid peptide which is considered to be a product of the KISS1 gene. Researchers have isolated smaller peptide fragments such as Kisspeptin 10, 13, and 14, which all have been suggested to possess some biological activity towards GPR54.⁽⁷⁾ These smaller peptides have been posited to bind with a low affinity to the GPR54 receptors and possibly stimulate calcium mobilization, arachidonic acid release, and extracellular protein kinase phosphorylation.⁽⁷⁾ These events may depolarize the Kisspeptin-10 neurons, possibly leading to the depolarization of the GnRH neurons and modulating gonadotropin release, to some extent.⁽⁹⁾

Research studies on Kisspeptin-10 have explored its potential in a wide variety of functions and impacts, and several hypotheses have been presented on the peptide’s possible mechanisms of action, including some notable hypotheses below:⁽⁸⁾

• That the Kisspeptin-10 peptide may potentially stimulate GnRH release;
• The peptide may potentially stimulate endogenous gonadotropin release in less-fertile animal models;
• Peptide concentrations may possibly induce desensitization and suppression of the hypothalamus, pituitary gland, and gonadal axis.
