Kisspeptin
The Master Reproductive Regulator
01
Overview
Kisspeptin (Kp-54, Kp-13, Kp-10) is a family of neuropeptides encoded by the KISS1 gene that play a critical role in the regulation of the hypothalamic-pituitary-gonadal (HPG) axis. Research has established kisspeptin signaling as the primary driver of GnRH pulse generation and as the central regulator of puberty onset, fertility, and reproductive function.
02
Mechanism of Action
Kisspeptin binds to its G-protein-coupled receptor GPR54 (KISS1R) on GnRH neurons in the hypothalamus, stimulating GnRH release and subsequent LH and FSH pulses from the pituitary. The arcuate nucleus kisspeptin/neurokinin B/dynorphin (KNDy) neurons form the GnRH pulse generator.
03
Research Highlights
Clinical trials in hypogonadotropic hypogonadism demonstrate LH pulse restoration
Human studies show induction of LH surges mimicking natural ovulatory patterns
Male fertility research demonstrates spermatogenesis support through gonadotropin stimulation
04
Dosage
Administration & Timing
Subcutaneous (SC) injection into abdominal or gluteal subcutaneous tissue or IV. Research protocols use once daily SC or IV bolus; timing may align with circadian GnRH pulsatility research.
Dosage Guidelines
Cycle Length
Variable; pulsatile administration over hours in acute research.
05
Reconstitution
Solvent
Bacteriostatic Water (0.9% benzyl alcohol)
Volume
2 mL added to a 5 mg vial
Concentration
2.5 mg/mL
Storage
Lyophilized powder: store at -20 °C long-term. Reconstituted: refrigerate 2–8 °C, use within 30 days.
Notes
Kisspeptin stimulates GnRH release upstream of LH/FSH. Research uses nmol/kg dosing — convert carefully to mcg.
