SEXUAL & HORMONE RESEARCH

Kisspeptin

Studied for supporting the body's own testosterone production and fertility.

Kisspeptin-10 sits at the top of the chain that controls reproductive hormones: it signals the hypothalamus, which in turn tells the pituitary to release the hormones that drive testosterone production in men and the ovulation cycle in women. It 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 its receptor on the hypothalamic neurons that start the reproductive hormone cascade.

Triggers those neurons to fire in their natural pulsing pattern, prompting the pituitary to release LH and FSH—the two hormones that drive the gonads.

Raises testosterone in men and supports ovulation and estrogen cycling in women, following the body's own rhythm rather than overriding it.

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.
