Kisspeptin-10

Also: KP-10, Metastin 45-54, KISS1

Reproductive Peptide

Last Updated: April 1, 2026

AI Reference Summary

Kisspeptin-10 (also known as KP-10, Metastin 45-54, KISS1) is a prominently researched experimental compound classified strictly within the Reproductive Peptide framework. Operating primarily through advanced pharmacological pathways, it functions by endogenous neuropeptide that is the master upstream regulator of the hypothalamic-pituitary-gonadal (HPG) axis. Kisspeptin-10 binds to the GPR54 (KISS1R) receptor on GnRH neurons, triggering pulsatile GnRH release which stimulates LH and FSH secretion from the pituitary. This cascade drives testosterone production in males and ovulation in females. Unique advantage: activates the reproductive axis at its highest control point without bypassing natural feedback loops. with a documented biological half-life of roughly 0.5 hours, in preclinical investigative trials and independent academic studies, researchers utilizing Kisspeptin-10 have documented significant, quantifiable biological outcomes, primarily focusing on lh/fsh stimulation, testosterone support, fertility enhancement, hpg axis activation. Typical research protocols investigate administering 100 to 100mcg via subq pathways 3x/wk. However, it is critically important to understand that while Kisspeptin-10 demonstrates profound physiological potential in highly controlled laboratory settings, it remains classified strictly as a research chemical and has not been approved by the United States Food and Drug Administration (FDA) for human therapeutic, diagnostic, or dietary consumption. Independent chemical analysis via rigorous third-party Certificate of Analysis (COA) testing utilizing High-Performance Liquid Chromatography (HPLC) and Mass Spectrometry (MS) remains the industry gold standard for verifying its base elemental stability when reconstituted appropriately in sterile bacteriostatic water.

How It Works

Endogenous neuropeptide that is the master upstream regulator of the hypothalamic-pituitary-gonadal (HPG) axis. Kisspeptin-10 binds to the GPR54 (KISS1R) receptor on GnRH neurons, triggering pulsatile GnRH release which stimulates LH and FSH secretion from the pituitary. This cascade drives testosterone production in males and ovulation in females. Unique advantage: activates the reproductive axis at its highest control point without bypassing natural feedback loops.

Key Studies

Kisspeptin potently stimulates LH and testosterone in healthy men

Dhillo et al. (J. Clin. Endocrinol. Metab.): IV Kisspeptin-10 (1mcg/kg) potently stimulates LH pulse frequency and testosterone secretion in healthy men, establishing its role as a reproductive axis activator.

moderate

Kisspeptin restores LH pulsatility in hypogonadal men

George et al.: Kisspeptin-10 infusion restores LH pulsatility and increases testosterone in men with type 2 diabetes-associated hypogonadism, demonstrating therapeutic potential.

moderate

Kisspeptin as alternative oocyte maturation trigger in IVF

Abbara et al. (J. Clin. Invest.): Kisspeptin-54 triggers oocyte maturation in women undergoing IVF with significantly lower risk of ovarian hyperstimulation syndrome (OHSS) vs. hCG trigger.

strong

Kisspeptin stimulates reproductive hormones in women

Jayasena et al.: Kisspeptin-10 administration increases LH secretion in women, with response magnitude dependent on menstrual cycle phase (strongest in preovulatory phase).

moderate

Kisspeptin tachyphylaxis with continuous administration

Ramaswamy et al.: Continuous Kisspeptin-10 infusion leads to desensitization of the HPG axis within 24-48 hours, indicating pulsatile dosing protocols are necessary for sustained efficacy.

preclinical

Safety Notes

Endogenous human neuropeptide with growing clinical trial data. Tachyphylaxis (desensitization) occurs with continuous dosing; pulsatile/intermittent protocols required. Being investigated as a safer IVF trigger (vs. hCG). Not FDA-approved for therapeutic use. Research-only.

Dosing Protocol

⚠️ For educational purposes only. Not medical advice. Consult a healthcare professional before using any peptide.

RouteSubQ
Dose Range100-100 mcg
Frequency3x/wk
TimingMorning or split AM/PM
Cycle Length8-8 weeks
BAC Water2.5 ml / 5mg vial

Pulsatile dosing critical: continuous administration causes desensitization within 24-48 hours. Clinical studies use 1mcg/kg IV or 100-400mcg SubQ. Cycle 5 days on / 2 days off to prevent tachyphylaxis. Monitor LH, FSH, testosterone/estradiol on bloodwork.

Expected Timeline

Week 1

Acute LH surge within hours; increase in morning testosterone levels; improved libido in hypogonadal individuals

Weeks 2-4

Sustained testosterone elevation with pulsatile dosing; improved energy and mood; fertility markers improving

Month 2-3

Stable HPG axis activation; measurable testosterone/LH improvement on bloodwork; improved reproductive parameters

Long-term

Must maintain pulsatile dosing to avoid desensitization; promising IVF trigger data; long-term reproductive axis support
