Kisspeptin-10

Kisspeptin 10mg – Professional Grade Peptide for Study of Reproductive and Neuroendocrine Systems

Detailed Technical Summary

Kisspeptin-10 (Metastin 45-54) represents a decapeptide subsequence derived from the full kisspeptin-1 protein architecture, functioning as the primary natural ligand for the GPR54 (KISS1R) receptor. Recognized as the central controller for the hypothalamic-pituitary-gonadal (HPG) axis, this influential neuropeptide governs the onset of puberty, the discharge of gonadotropin-releasing hormone (GnRH), and overall fertility. Its robust capacity to trigger GnRH liberation and subsequent spikes in gonadotropin levels establishes it as a critical instrument for exploring reproductive biology, endocrine pathologies, and neuroendocrine signaling networks.

At PX1 Research, we supply pharmaceutical-level Kisspeptin-10 (minimum 98% purity) in 10mg freeze-dried vials, validated through HPLC and mass spectrometry to ensure maximum stability and experimental dependability. This reagent is developed strictly for in vitro and animal-based laboratory experimentation and is not suitable for human or veterinary applications.

Functioning as the endogenous ligand for GPR54 (KISS1R), Kisspeptin-10 is the primary supervisor of the HPG axis. It is optimized for investigating:

Processes of GnRH discharge & gonadotropin release Mechanisms of pubertal onset & sexual maturation Pathways for fertility management & ovulation triggering Interactions between metabolic state and reproductive health

***This specific peptide contains a high concentration of hydrophobic (water-repelling) amino acid residues which naturally aggregate rather than dissolving smoothly in standard liquids. While its hydrophobicity is less intense than that of AOD-9604, it possesses unique traits that often lead to cloudiness or clumps. WE DO NOT ACCEPT RESPONSIBILITY FOR THESE PHYSICAL CHARACTERISTICS***

Mechanism of Action: Advanced Neuroendocrine Pathways

Kisspeptin-10 operates via complex receptor engagement and intracellular signaling:

• GPR54/KISS1R Interaction: It binds with high selectivity to the G protein-coupled receptor 54 (GPR54), initiating the signaling events required for GnRH secretion (Kotani et al., 2001).

• Activation of GnRH Neurons: It directly stimulates GnRH-producing neurons located in the arcuate and anteroventral periventricular nuclei of the hypothalamus, acting as the main catalyst for gonadotropin release (Gottsch et al., 2004).

• Pulsatility Management: It regulates the frequency and strength of GnRH pulses, thereby dictates the release patterns of LH and FSH (Plant, 2015).

• Feedback Loop Integration: It acts as a vital bridge for sex steroid hormone feedback within the HPG framework, specifically mediating the negative feedback effects of estrogen (Smith et al., 2005).

Key Research Applications & Evidence-Based Studies

1. Reproductive Endocrinology Research

In the field of reproduction, Kisspeptin-10 has shown significant efficacy:

GnRH Stimulation Analysis:

• Methodology: 0.1-1.0 μg/kg via intravenous bolus in non-human primates.
• Findings: Rapid, dose-proportional elevations in GnRH and LH were observed within a 15-30 minute window (Plant et al., 2006).
• Pathway: Direct stimulation of hypothalamic GnRH-secreting neurons.

Pubertal Timing Study:

• Methodology: 1.0 nmol/hour via constant infusion in pre-pubertal rodent subjects.
• Findings: Triggered early-onset puberty by stimulating the HPG axis (Seminara et al., 2003).

2. Fertility and Reproductive Function Studies

Experiments highlight the role of Kisspeptin-10 in fertility science:

Induction of Ovulation:

• Methodology: 6.4-12.8 nmol/kg administered subcutaneously in non-ovulating models.
• Findings: Successfully stimulated ovulation by facilitating a synchronized LH surge (Caraty et al., 2007).

Regulation of Spermatogenesis:

• Methodology: 0.5-2.0 nmol/kg given twice daily in male subjects.
• Findings: Led to improvements in testosterone levels and sperm production metrics (Irfan et al., 2014).

3. Metabolic and Reproductive Integration

New data indicates vital links between energy status and fertility:

Metabolic Support of Fertility:

• Methodology: 0.1-0.5 μg/kg via intravenous route in models of metabolic deficiency.
• Findings: Revived reproductive capabilities in subjects with metabolic impairment (Smith et al., 2006).

Energy Balance Dynamics:

• Methodology: 1.0 nmol/hour via continuous pump in energy-deprived subjects.
• Findings: Counteracted diet-based reproductive decline through the restart of the HPG axis (Castellano et al., 2005).
