Overview

Kisspeptin is a master regulator of reproduction — it triggers the release of GnRH, which cascades down to LH, FSH, and the sex hormones. Kisspeptin-10 is the short active fragment, studied for fertility, hypogonadism, and sexual response.

How it’s thought to work

  • Stimulates GnRH neurons, driving downstream LH/FSH and sex-hormone release.
  • Sits upstream of the entire hypothalamic-pituitary-gonadal axis.

Researched uses

  • Fertility and reproductive-hormone research
  • Libido and hypogonadism studies

Commonly cited protocol

Typical dose~1 mg (varies widely)
FrequencyVaries
RouteSubcutaneous injection
NotesClinical research uses precise, weight-based dosing.

Reconstitution

Often a 5 mg vial. 5 mg with 2 mL water = 2.5 mg/mL, so 1 mg = 40 units on a U-100 syringe.

📋 In plain English

Add 2 mL of bacteriostatic water to your 5 mg vial. That gives you about 5 doses of 1 mg. For each dose, draw 40 units into a 100-unit insulin syringe.

Cautions

  • Not approved for general use.
  • Affects the whole reproductive-hormone axis — effects can be complex.
  • Consult a clinician, especially with hormone-sensitive conditions.
