Kisspeptin

Decapeptide · Sexual Health Track

What it is

Kisspeptin is a hypothalamic peptide that sits at the top of the male hormonal axis — the upstream regulator that tells the pituitary when to release LH, which in turn drives endogenous testosterone production. When the system slows down with age or stress, kisspeptin is the lever that resets the signal at its origin.

Who it’s for

The man whose libido isn’t matching his lab numbers. Patients exploring HPG axis support without going straight to TRT. Useful as a discrete protocol or as part of a broader Sexual Health Track stack alongside PT-141 or Gonadorelin, depending on what your provider determines fits the goal.

How it works

Kisspeptin acts on KISS1R receptors in the hypothalamus, triggering GnRH pulses that drive LH and FSH release. Downstream, that means stronger endogenous testosterone signaling, sharper libido response, and a recalibrated hormonal rhythm. Most patients notice changes in libido and morning vitality within two to three weeks. Stay on track and reassess at 30 days.
