SEXUAL & HORMONE RESEARCH

Kisspeptin

A decapeptide that stimulates GnRH release, studied for reproductive hormone regulation and testosterone support.

Kisspeptin-10 is a decapeptide that stimulates GnRH release from the hypothalamus, driving LH and FSH secretion. It plays a central role in reproductive hormone regulation and is studied for natural testosterone support and fertility, with human infusion studies documenting its hormone effects.

Why BLP features Kisspeptin

Included because it has documented human research (including infusion studies with measured LH and testosterone responses) and a very well-defined receptor mechanism. Its real-world use history is still developing, placing it as an emerging reproductive-research compound.

Mechanism

Binds GPR54 (KISS1R) receptors on GnRH neurons.

Triggers pulsatile GnRH release, stimulating pituitary LH and FSH secretion.

Increases downstream testosterone in men and supports ovulation/estrogen dynamics in women, in a physiological pattern.

WHAT THE RESEARCH MEASURED

Research findings

Findings describe study outcomes, not expected personal results.

Human research findings

  • Human research reports rapid, dose-dependent increases in serum LH and FSH.
  • Reported testosterone increases in healthy men with infusions or boluses.
  • Reported enhanced LH pulse frequency and amplitude, with potential libido and reproductive effects.
  • Mostly well tolerated; rare mild injection-site reactions.

Mechanistic & supporting research

  • Receptor mechanism (GPR54/KISS1R) very well characterized.
  • Reproductive-axis effects documented in human and animal research.

Regulatory status

Kisspeptin is investigational and not FDA-approved. Sold and offered strictly for laboratory and research use.
