Kisspeptin-10 is the shortest biologically active fragment of the KISS1 gene product that fully retains potency at the kisspeptin receptor (KISS1R/GPR54). First identified in 2001 as the endogenous ligand associated with pubertal onset, it is now recognized as a key upstream regulator of pulsatile GnRH secretion in experimental models. According to published research, kisspeptin-10 activates GnRH neurons in the hypothalamus through G-protein-coupled receptor signaling, leading to downstream effects on LH and FSH secretion (ncbi.nlm.nih.gov). This research-grade lyophilized powder is synthesized under strict quality controls and provided with full analytical documentation. For Research Use Only. Not for human use.
Key Scientific Attributes
- High-purity Kisspeptin-10 (≥99% by HPLC/MS, acetate or TFA salt form)
- Verified native decapeptide sequence: Tyr-Asn-Trp-Asn-Ser-Phe-Gly-Leu-Arg-Phe-NH₂
- Lyophilized formulation for maximum long-term stability
- Full Certificate of Analysis (COA) with HPLC, MS, and amino acid analysis
- Manufactured in GMP-aligned, ISO-compliant facilities
- Studied in the context of GnRH neuron activation and LH/FSH pulsatility research
Research Context (Based on scientific literature; not intended as therapeutic claims.)
- Acts as an upstream regulator of GnRH secretion via KISS1R on hypothalamic GnRH neurons, as documented in neuroendocrine research (pmc.ncbi.nlm.nih.gov)
- Used in experimental models investigating hypothalamic–pituitary–gonadal (HPG) axis signaling
- The most commonly used kisspeptin fragment in biomedical research due to its defined receptor affinity and short sequence
- Studied in reproductive neuroendocrinology, including investigations of GnRH pulse regulation and gonadotropin release

Frequently asked questions
How should I reconstitute this peptide?
Use bacteriostatic water for short-term lab storage. Direct the diluent down the side of the vial, swirl gently — do not shake.
What is the shelf life?
Lyophilized peptide stored at −20°C is stable for 24+ months. Reconstituted peptide should be refrigerated and used within 2–4 weeks.
Do you ship internationally?
We currently ship within the United States only. International researchers should contact our bulk team for institutional quotes.
