It is a ligand of the KISS1R receptor.<\/p>\n<h3>What is KISS1R?<\/h3>\n<p>KISS1R is a G-protein receptor activated by kisspeptins. The name GPR54 is often used in older scientific publications.<\/p>\n<h3>What is being studied with Kisspeptin-10?<\/h3>\n<p>The research involves the receptor signaling KISS1R, GnRH neuronal mechanisms, the dynamics of LH, and other questions of neuroendocrine biology.<\/p>\n<h3>Are there studies of Kisspeptin-10 in humans?<\/h3>\n<p>Yes. Mechanistic and physiological studies have been published in healthy men and women. However, their results apply to precisely defined research protocols and cannot be automatically transferred to other applications or research-grade materials.<\/p>\n<h3>Is Kisspeptin-10 the same as Kisspeptin-54?<\/h3>\n<p>No. Both molecules belong to the kisspeptin system and share a biologically active C-terminal region, but they differ in length and pharmacological properties. Therefore, the results of their studies cannot be automatically confused.<\/p>\n<h3>Does the change in LH in the study mean a health benefit?<\/h3>\n<p>No. LH is a measurable neuroendocrine parameter in these experiments. A change in a laboratory or hormonal endpoint by itself does not constitute evidence of a health or therapeutic benefit.<\/p>\n<h3>How is research-grade Kisspeptin-10 stored?<\/h3>\n<p>Storage is <strong>\u201320 \u00b0C or 2\u20138 \u00b0C according to the label and the CoA of the specific batch<\/strong>. In the case of a specific product, the conditions specified in its technical documentation always take precedence.<\/p>\n<h3>Is an HPLC purity value sufficient?<\/h3>\n<p>No. HPLC purity is only one analytical parameter. Identity, quantity, molecular form, batch, and other analytical data must be evaluated separately.<\/p>\n<p>You can find more professional articles in the section <a href=\"https:\/\/nexxusbio.com\/en\/category\/peptide-analysis\/\"><strong>Research on peptides<\/strong><\/a>.<\/p>\n<h2 id=\"zdroje-kp10\">Scientific and regulatory sources<\/h2>\n<ol>\n<li>George JT, Veldhuis JD, Roseweir AK, et al. <em>Kisspeptin-10 is a potent stimulator of LH and increases pulse frequency in men.<\/em> J Clin Endocrinol Metab. 2011. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21632807\/\" target=\"_blank\" rel=\"noopener noreferrer\">PubMed<\/a><\/li>\n<li>Chan YM, Butler JP, Pinnell NE, et al. <em>Kisspeptin resets the hypothalamic GnRH clock in men.<\/em> J Clin Endocrinol Metab. 2011. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/21470997\/\" target=\"_blank\" rel=\"noopener noreferrer\">PubMed<\/a><\/li>\n<li>Chan YM, Butler JP, Sidhoum VF, et al. <em>Administration of Kisspeptin to Women: A Window into Endogenous Kisspeptin Secretion and GnRH Response Across the Menstrual Cycle.<\/em> J Clin Endocrinol Metab. 2012. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/22577171\/\" target=\"_blank\" rel=\"noopener noreferrer\">PubMed<\/a><\/li>\n<li>Topaloglu AK, Tello JA, Kotan LD, et al. <em>Inactivation of the KISS1 mutation and hypogonadotropic hypogonadism.<\/em> New England Journal of Medicine. 2012. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/22335740\/\" target=\"_blank\" rel=\"noopener noreferrer\">PubMed<\/a><\/li>\n<li><em>Single-cell analyses reveal that KISS1R-expressing cells undergo sustained kisspeptin-induced signaling dependent upon extracellular Ca\u00b2\u207a.<\/em> <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/23070548\/\" target=\"_blank\" rel=\"noopener noreferrer\">PubMed<\/a><\/li>\n<li><em>Dynamic modulation of LH secretion by continuous kisspeptin infusion in healthy men.<\/em> 2026. <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/42230485\/\" target=\"_blank\" rel=\"noopener noreferrer\">PubMed<\/a><\/li>\n<li><em>LC-MS\/MS quantification of kisspeptin-10 and characterization of its decomposition product and pharmacokinetics.<\/em> <a href=\"https:\/\/pubmed.ncbi.nlm.nih.gov\/23524040\/\" target=\"_blank\" rel=\"noopener noreferrer\">PubMed<\/a><\/li>\n<li>PubChem. <em>Kisspeptin-10 \u2013 CID 25240297.<\/em> <a href=\"https:\/\/pubchem.ncbi.nlm.nih.gov\/compound\/Kisspeptin-10\" target=\"_blank\" rel=\"noopener noreferrer\">PubChem<\/a><\/li>\n<li>U.S. Food and Drug Administration. <em>Certain Bulk Drug Substances for Use in Compounding that May Present Significant Safety Risks.<\/em> <a href=\"https:\/\/www.fda.gov\/drugs\/human-drug-compounding\/certain-bulk-drug-substances-use-compounding-may-present-significant-safety-risks\" target=\"_blank\" rel=\"noopener noreferrer\">FDA<\/a><\/li>\n<\/ol>\n<div style=\"background: #fff8dc; border: 1px solid #eadb99; border-left: 5px solid #d6b94c; padding: 18px 20px; margin: 30px 0; border-radius: 6px;\"><strong>Important notice:<\/strong><\/p>\n<p>This article is for informational, educational, and scientific purposes only.
