Kisspeptin-10 (10mg) Research Peptide: A Decapeptide Agonist for GPR54 & Neuroendocrine Studies
If your research investigates the hypothalamic-pituitary-gonadal (HPG) axis, reproductive endocrinology, or the molecular mechanisms of neuroendocrine signalling, Kisspeptin-10 (10mg) research peptide offers a precisely defined and extensively validated synthetic tool. Kisspeptin-10 (KP-10, Metastin 45-54) is the C‑terminal decapeptide amide of the kisspeptin precursor protein, which is the endogenous ligand for the G protein‑coupled receptor GPR54 (also known as KISS1R).
As the minimal bioactive sequence that retains full functional activity, Kisspeptin-10 exhibits higher receptor affinity and biopotency than longer forms of the peptide. It binds with high affinity to rat and human KISS1 receptors with Ki values of 1.59 nM and 2.33 nM, respectively. This makes Kisspeptin-10 (10mg) research peptide a valuable tool for laboratories investigating reproductive endocrinology, neuroendocrine signalling, metastasis suppression, and bone metabolism.
At Chinese Grey Peptides, we supply high‑purity Kisspeptin-10 (10mg) research peptide to research institutions and wholesale buyers across the United Kingdom, France, Germany, Spain, Sweden, Italy, and the USA. Every batch is lyophilised, HPLC‑verified to ≥98% purity, and accompanied by a Certificate of Analysis (COA), ensuring your investigations into the HPG axis, receptor pharmacology, and neuroendocrine signalling begin with uncompromising quality.
What Is Kisspeptin-10 and How Does It Work?
To fully appreciate the research potential of Kisspeptin-10 (10mg) research peptide, it is essential to understand its biochemical structure and the precise mechanism by which it exerts its effects.
The Decapeptide Derived from KISS1
Kisspeptin-10 is a synthetic decapeptide corresponding to the C‑terminal amino acids 45-54 of the kisspeptin precursor protein (metastin). Its sequence is Tyr‑Asn‑Trp‑Asn‑Ser‑Phe‑Gly‑Leu‑Arg‑Phe‑NH₂ (YNWNSFGLRF-NH₂). The peptide has a molecular formula of C₆₃H₈₃N₁₇O₁₄, a molecular weight of approximately 1,302.4‑1,302.45 g/mol, and a CAS number of 374675-21-5. The C‑terminal amidation is essential for its biological activity.
Mechanism of Action: GPR54 (KISS1R) Agonism
The biological activity of Kisspeptin-10 (10mg) research peptide is mediated through its potent and selective activation of the Kisspeptin receptor (KISS1, GPR54):
-
High‑Affinity Receptor Binding: Kisspeptin-10 binds with high affinity to rat and human KISS1 receptors with Ki values of 1.59 nM and 2.33 nM, respectively. It exhibits approximately 8‑fold higher binding affinity compared to the full‑length metastin peptide. The receptor is primarily coupled to the Gαq/11 subunit.
-
HPG Axis Regulation: Activation of GPR54 in the hypothalamus stimulates the release of luteinising hormone‑releasing hormone (LHRH) from hypothalamic explants. This, in turn, drives the secretion of luteinising hormone (LH) and follicle‑stimulating hormone (FSH) from the pituitary, leading to increased gonadal steroidogenesis. Kisspeptin-10 is a potent stimulator of LH and increases LH pulse frequency in men.
-
Direct Pituitary Effects: Kisspeptins also exert direct effects on the pituitary, activating gonadotrophs and somatotrophs and stimulating the secretion of LH and growth hormone.
-
Metastasis Suppression: The KISS1 gene was originally discovered as a metastasis suppressor gene. Kisspeptin-10 inhibits tumour angiogenesis and metastasis via its receptor GPR54.
-
Bone Metabolism: GPR54 activation by Kisspeptin-10 in osteoclasts suppresses osteoclast activity and prevents bone loss.

Reconstitution & Handling Protocol for Kisspeptin-10 (10mg)
Proper reconstitution of Kisspeptin-10 (10mg) research peptide is critical for maintaining its structural integrity and biological activity. The peptide has a very rapid clearance in vivo, so careful handling is essential.
Step 1 – Preparation
-
Bring the sealed Kisspeptin-10 vial and your chosen diluent (sterile bacteriostatic water or sterile PBS, pH 5‑7) to room temperature. Condensation can degrade the lyophilised powder.
-
Clean your work surface with 70% ethanol and lay out sterile syringes, alcohol wipes and a clean work mat.
Step 2 – Vial Sanitisation
-
Wipe the rubber stopper of the Kisspeptin-10 vial with a fresh 70% ethanol wipe. Allow the alcohol to evaporate completely before piercing.
Step 3 – Reconstitution
-
Draw your desired volume of diluent into a sterile syringe. A common starting concentration for research applications is 10 mg per 1 mL of diluent, yielding a 10 mg/mL stock solution.
-
Insert the needle and slowly inject the diluent against the inner glass wall. Do not spray directly onto the lyophilised powder.
-
Gently swirl the vial until the solution is clear and fully dissolved. Do not shake vigorously, as shaking can cause denaturation.
Step 4 – Aliquoting & Storage
-
Immediately after dissolution, aliquot the reconstituted Kisspeptin-10 into single‑use sterile vials.
-
Store aliquots at –20°C. Avoid repeated freeze‑thaw cycles, as peptides are susceptible to degradation.
-
Once thawed, store at 2‑8°C and use within a short period.
