What is the difference between Kisspeptin-10 and Gonadorelin?

Kisspeptin-10 (Kisspeptin-10 (KP-10)) is graded B and is Not FDA-approved — used in clinical research as a kisspeptin/GnRH stimulus test. Gonadorelin (Gonadorelin (GnRH)) is graded A and is FDA-approved (Factrel) historically for diagnostic GnRH stimulation; off-label use in TRT to preserve testicular function. They are commonly compared because they share the categories: sexual-health, fertility.

Which has stronger clinical evidence — Kisspeptin-10 or Gonadorelin?

On our internal evidence scale, Kisspeptin-10 is B and Gonadorelin is A. A+ indicates large RCTs plus FDA approval; C indicates primarily preclinical or anecdotal evidence.

What is the typical dose of Kisspeptin-10 vs Gonadorelin?

Kisspeptin-10: Trial range: 0.1–10 mcg/kg IV/SC bolus. Gonadorelin: 100–500 mcg every 1–3 days (subcutaneous, pulsatile). Always work with a licensed clinician — peptide dosing should be individualized.

Kisspeptin-10 vs Gonadorelin

Both Kisspeptin-10 and Gonadorelin are used for sexual-health and fertility. Here's how their evidence, dosing, and regulatory status actually compare.

Kisspeptin-10

Evidence B

Kisspeptin-10 (KP-10)

A 10-amino-acid neuropeptide that triggers GnRH release. Studied as a more physiologic alternative to hCG/GnRH for fertility, libido, and HPG-axis assessment.

Gonadorelin

Evidence A

Gonadorelin (GnRH)

Synthetic GnRH used clinically to stimulate LH/FSH release. In testosterone replacement therapy, used pulsatile to preserve testicular size and fertility instead of hCG.
