Kisspeptin-10
BHuman Studies

Excellent Credibility
Not FDA Approved
Kisspeptin-10 is the minimal active fragment of kisspeptin (metastin), the endogenous ligand for the KISS1 receptor (GPR54). It is a potent stimulator of the hypothalamic-pituitary-gonadal (HPG) axis, triggering GnRH release and downstream LH/FSH secretion. First identified for its anti-metastatic properties in melanoma, it is now primarily studied for reproductive medicine applications including fertility treatment and hypothalamic amenorrhea.
Mechanism of Action
Binds to and activates the KISS1 receptor (GPR54/KISS1R) on hypothalamic GnRH neurons. This stimulates pulsatile GnRH release into the hypophyseal portal system, which in turn triggers the anterior pituitary to secrete luteinizing hormone (LH) and follicle-stimulating hormone (FSH). Unlike exogenous gonadotropins, kisspeptin preserves physiological pulsatile hormone secretion patterns. Also modulates oxytocin release in a sex-dependent manner.
Benefits
- Triggers egg maturation in women undergoing IVF — demonstrated in clinical studies[3]
- Stimulates gonadotropin secretion without causing the hormonal surge crash seen with GnRH agonists[1]
- Modulates reproductive hormones in PCOS patients without hyperstimulation[4]
- May have therapeutic potential for hypothalamic amenorrhea and delayed puberty[1]

Kisspeptin-10 - Dosing in Published Research
Reported routes: Intravenous infusion, Subcutaneous injection
In clinical studies, kisspeptin-10 is administered by intravenous infusion at doses of 0.1–1.0 nmol/kg. Subcutaneous administration is also studied but has lower bioavailability. Bolus vs continuous infusion produces different LH response patterns. Typical research protocols use 0.3 nmol/kg IV bolus. No established subcutaneous dosing regimen.
The dosing information above is sourced from published research literature and clinical trials. These are not recommendations. Individual responses vary. Always consult a healthcare provider before considering any peptide-based therapy.
Side Effects
- Generally well-tolerated in clinical studies — no serious adverse events reported at therapeutic doses[2][1]
- No significant effect on anxiety or mood in human studies[2]
- Sex-dependent effects on oxytocin — women show greater oxytocin response
- Long-term effects of repeated administration not fully characterized[1]
