Kisspeptin-10
Also called KP-10, kisspeptin 10
Kisspeptin-10 is the master switch at the very top of your reproductive hormone system.
Studied in people, in small numbers. The ranges below lean mostly on community-reported dosing and results — what people run, and what they say happened.
- Hormone balance
- Sexual health
The quick answer
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.

What people report using
These are ranges other people have reported running. They are here so you can see what has actually been done — they are not medical advice and not a recommendation for you.
Sexual health
- How often
- Mon and Thu, morning
- Route
- subcutaneous
- Where this comes from
- Small human studies
Mixed, honestly.
10mg vial + 2ml BAC water = 5mg/ml. 0.1mg = 2u, 0.2mg = 4u. Morning, Mon and Thu.
Work out your own units on the reconstitution calculator — the most common serious mistake in this area is arithmetic, not chemistry.
What to expect, and when
- First thing people notice
- Days 1–7 (HPG signal)
- When it gets real
- Weeks 2–3 (LH/T rising)
- Where it peaks
- Weeks 4–8 (full hormonal response)
- Patience needed
- Medium - lab work at 4 wks
- Days 1–7HPG-axis signaling engaged
Kisspeptin-10 acts upstream on GnRH neurons to stimulate the hypothalamic-pituitary-gonadal axis. In controlled human studies, intravenous doses produced a rapid, dose-dependent rise in LH within minutes to hours - so first signal is acute in a study setting, not week-scale. The weekly framing here reflects a hypothetical repeated-exposure research context rather than a single dose.
- Weeks 2–3LH pulse frequency & testosterone trending up
Continuous-infusion research showed kisspeptin-10 increased mean LH, LH pulse frequency, and LH pulse size in men, with serum testosterone rising over the infusion period. Research suggests the effect works by amplifying the body's own pulsatile signaling rather than replacing hormones. A repeated-exposure protocol is where trending lab changes would plausibly appear.
- Weeks 4–8Fuller hormonal response; lab-confirmed
In clinical studies, kisspeptin's downstream effects on LH, FSH, and testosterone were established through blood sampling, and researchers frame it as a potential investigational signaling agent. Around the 4-week mark is where lab work would meaningfully characterize an individual's response. Responsiveness varies with dose, sex, and underlying HPG status, and desensitization at high continuous doses is a documented concern.
Nearly all human data come from short-term IV infusion studies in controlled settings; sustained multi-week self-administration is not well studied, and monitoring hormone labs with a clinician is essential.
Side effects, and what people do about them
Gentle and short-acting by design. Since it gently fires up your own hormones, the main thing you'll feel is that natural lift itself, and its very short action means anything passes quickly. Injection-site reactions are mild. An easy one for most people.

How it actually works
Ten-amino-acid fragment of kisspeptin, binding KISS1R (also called GPR54) on GnRH neurons in the hypothalamus. It sits at the top of the reproductive axis: kisspeptin drives GnRH, GnRH drives pituitary LH and FSH, and those drive the gonads.
For stacking, that position is the whole point. It works upstream, so it depends on the whole chain below it being intact. HCG replaces LH directly and works whether or not the chain above is functioning. They are two different answers to two different problems, and running both is redundant rather than additive.
What people report, in full
Kisspeptin draws a more science-minded, lab-tracking crowd, and the one non-negotiable rule everyone repeats is cycling - a month on, a month off - because running it continuously can dull the receptor. On-cycle, about 75–80% report the expected hormone rise plus a subjective lift in libido and drive; the remaining 20–25% notice little. Sticking to the cycling seems to matter far more than the exact dose. The hormone effects are easy to confirm on bloodwork; the arousal side is more subjective.
Worth knowing
The trials are real. They were not asking the question most people are asking when they come looking for this one.
