KissPeptin-10  Research-Grade Peptide

KissPeptin-10 is a 10-amino acid neuropeptide fragment. It’s derived from the full kisspeptin sequence. Researchers use it to study GnRH pulse regulation and hypothalamic signaling pathways. So if you need a clean, verified compound, this is where to start.

Available at ZenPeptideAmanda  verified, documented, and ready for the bench.

For research use only. Not for human or veterinary use.

Is KissPeptin-10 Third-Party Tested?

Yes. Every batch sold at ZenPeptideAmanda goes through Janoshik — an independent analytical lab. They test for purity, identity, and sequence accuracy. So you’re not just taking our word for it. The numbers come from outside our facility.

Also, each COA is batch-specific. That means the certificate matches your exact vial, not some generic sample from six months ago. That matters when your data depends on compound consistency.

What Is the KissPeptin-10 Sequence?

The full sequence is: Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Trp-NH₂

Again, This is the C-terminal 10-amino acid fragment of the KISS1 gene product. It’s also called metastin (45–54) or KP-10. However, KissPeptin-10 is the name most researchers recognize in the literature. First isolated in the early 2000s, it’s now one of the most referenced GnRH regulatory peptides in neuroendocrine research.

The molecular formula is C₆₃H₈₃N₁₅O₁₃. Molecular weight sits at 1302.43 g/mol. Therefore, when preparing stock solutions for research, verify these values against your COA before proceeding.

How Should KissPeptin-10 Be Stored?

Store at −20°C. Keep it dry. Keep it dark. That’s the short answer.

But here’s more detail. First, lyophilized powder is stable at −20°C for up to 24 months when stored correctly. Next, once reconstituted, use the solution within your standard research window. Finally, avoid repeated freeze-thaw cycles. Each cycle degrades structural integrity. So aliquot before freezing if you’re running repeated experiments.

ZenPeptideAmanda ships all peptides using appropriate cold-chain practices. The compound arrives ready for your storage protocol.

How Pure Is the KissPeptin-10 From ZenPeptideAmanda?

Purity is ≥99% — confirmed by Janoshik. Not estimated. Not assumed. Tested.

However, purity numbers only mean something when they come from a real third-party report. So we don’t post generic figures. We post the actual batch COA. You can verify it yourself directly through Janoshik’s platform. That’s the level of documentation your research deserves.

Also, our lyophilized powder shows no visible degradation or clumping. That’s a basic quality check but it matters. Clean powder at the right storage temp means your reconstitution will be consistent.

Frequently Asked Questions

Q: What is KissPeptin-10 used for in research?
A: It’s used to study the hypothalamic–pituitary–gonadal (HPG) axis. Specifically, researchers look at how it regulates GnRH pulse secretion. Also studied in the context of reproductive neuroendocrinology and energy homeostasis signaling.

Q: Is KissPeptin-10 the same as metastin?
A: Yes and no. Metastin is the full 54-amino acid protein. KissPeptin-10 is just the C-terminal 10-residue fragment. But it’s the fragment with the most biological signaling activity studied in the literature. So when researchers say “kisspeptin,” they often mean KP-10 specifically.

Q: What solvent do researchers use to reconstitute KissPeptin-10?
A: Most protocols use sterile water or 0.1% acetic acid for initial reconstitution. However, check your specific assay protocol. Solubility varies depending on the vehicle and concentration needed.

Q: How do I verify the Janoshik COA for my batch?
A: Your COA includes a batch number. You can cross-reference that batch directly on the Janoshik website. Their reports are publicly searchable. Therefore, you don’t have to trust us — you can verify it yourself.

Q: What’s the difference between KP-10, KP-13, KP-54, and KP-1?
A: These are all fragments of the same KISS1 gene product. They differ in length. KP-10 (kisspeptin-10) is the shortest active fragment widely used in research. KP-54 is the full protein. KP-13 and KP-1 are intermediate or shorter fragments with less documented research use.

Q: Is lyophilized KissPeptin-10 more stable than a solution?
A: Yes. Lyophilized powder is significantly more stable for long-term storage. Solutions degrade faster, especially with repeated temperature changes. So for research labs ordering in advance, lyophilized is the correct form.

Q: Does ZenPeptideAmanda ship internationally?
A: Check the current shipping policy at ZenPeptideAmanda. Shipping options and availability depend on destination. Contact the team directly for specific regional questions.
