Kisspeptin-10

KISS1 peptide · upstream HPG-axis signaling (research)

The hormonal ignition switch. Kisspeptin-10 signals your body to fire up its own testosterone and sex hormones — the natural way.

What it is

Kisspeptin-10 is the master switch at the very top of your reproductive hormone system. One signal from it sets off a chain reaction — GnRH, then LH and FSH, then testosterone or estrogen — so it's a way to fire up your own hormones rather than replace them.

Because the body's own signal comes in short pulses, it's dosed intermittently to mimic that rhythm, and cycling (roughly a month on, a month off) is the near-universal approach. People report subtle lifts in libido, mood, and drive over the first couple of weeks. Honest note: most human data comes from short research studies, so the libido benefits and the cycling routine lean on real-world experience more than trials.

Small human studies Studied in people, but in small groups rather than large trials.

Your dosing

0.2 mg · Mon and Thu, morning

Two weeks at 0.1mg (2 units), then 0.2mg (4 units) and stay there.

That is 4 units on a U-100 insulin syringe — from a 10 mg vial mixed with 2 ml of water, which gives you 5 mg/ml.

Add the water slowly down the inside of the glass and roll it — never shake it. Keep it in the fridge at 2–8 °C once mixed.

What the lab found

Every batch is independently assayed before it is sold, and the lab measures how much peptide is actually in the vial — not just how pure it is. The most recent batch tested here came in 19% over the labelled amount. That is deliberate: we would rather you got more than you paid for than less.
