Is kisspeptin the same as GnRH?

No. Kisspeptin acts upstream of GnRH -- it stimulates GnRH neurons to release GnRH, which then triggers LH and FSH release. They are distinct peptides with different receptors (GPR54 vs GnRH receptor).

Can kisspeptin be used for fertility treatment?

It is actively researched for this purpose, particularly as an IVF trigger with lower OHSS risk than hCG (Jayasena et al., J Clin Invest, 2014). Also being studied for hypothalamic amenorrhea. Not yet approved for fertility treatment.

How does kisspeptin differ from hCG or clomiphene for testosterone?

Kisspeptin works at the very top of the HPG axis (hypothalamus), triggering the natural cascade: kisspeptin -> GnRH -> LH/FSH -> testosterone. Clomiphene blocks estrogen feedback at the pituitary. hCG directly mimics LH at the testicular level. Kisspeptin's advantage is maintaining the full natural cascade without axis suppression.

What is the recommended dose range for Kisspeptin?

The research dose range is SC: 50–100 mcg per dose; IV research: up to 10 mcg/kg, administered via Subcutaneous or Intravenous (research), Once daily or pulsatile (every 60–90 min for fertility protocols).
