GnRH pulse restoration (amenorrhea) 0.3–1.0 nmol/kg Subcutaneous Every 90 min × 12–24 hrs 1 pulse per 90 min, peak 8–12 IU/L Mimics endogenous kisspeptin neuron firing; requires multi-dose commitment but produ…
Subcutaneous administration is the standard route for reproductive endocrine research. It mimics the pulsatile endogenous kisspeptin release from ARC neurons while maintaining stable plasma levels for 60–90 mi…
Physiological pulsatile stimulation 0.24–1.0 nmol/kg 0.75–3.0 nmol/kg 2–5 IU/L peak, mirrors endogenous pulse 60–90 min intervals, 24–48 hr Hypothalamic amenorrhea models, pubertal timing research Maximal GnRH…
Single IV Bolus (Standard) Kisspeptin-54 1.0 IV 12–15 150–180 Low Gold standard for acute LH stimulation. Highest reproducibility, minimal receptor fatigue Single SC Bolus (Adjusted) 1.5 Subcutaneous 11–14 140…

Kisspeptin's dual mechanism. Peripheral gonadotropin release and central limbic activation. Creates a dosing bifurcation that determines research outcomes. Peripheral effects (LH surge, testosterone elevation,…
IV Bolus 1–2 nmol/kg 30–60 minutes 60–90 minutes Direct CNS delivery; limbic KISS1R activation Imperial College fMRI study. Increased posterior cingulate activity during sexual stimuli exposure Subcutaneous 10…
2mg 2mL 1000µg/mL 0.10mL 10 units Easiest for beginners. Large dose volume reduces measurement error 5mg 2500µg/mL 0.04mL 4 units Standard research protocol. Balances concentration with injection frequency 5mL…
Reproductive Endocrinology Research 0.01–10 nmol/kg bolus or 0.1–4.0 nmol/kg/hr infusion IV or SC Single bolus or continuous infusion 1–8 hours LH pulsatility, FSH response, GnRH neuron activation Use molar do…
Endogenous GnRH is secreted in pulses every 60–120 minutes. Continuous GnRH receptor stimulation paradoxically downregulates gonadotropin release, the mechanism exploited by GnRH agonist therapies for prostate…
Single IV bolus administration (0.24–1.0 nmol/kg) produces a single LH pulse peaking at 60–90 minutes post-injection, followed by return to baseline within 3–4 hours. This mimics the endogenous LH surge seen a…

Acute GnRH stimulation (single-dose) Kisspeptin-10 IV 1.0–2.0 Single bolus 250–400% Best for rapid-onset LH measurement without sustained effect Sustained LH elevation (4–6 hours) Kisspeptin-54 0.5–1.0 150–250…
IV Bolus 0.24–1.0 60–90 minutes 3.0–4.5× 2–3 hours Gold standard for acute stimulation studies; minimal pharmacokinetic variability, dose-response relationship is well-characterised, ceiling effect above 1.0 n…
Intravenous administration bypasses hepatic first-pass metabolism and delivers 100% bioavailability, meaning the entire administered dose reaches systemic circulation and can cross the blood-brain barrier to a…
The single most predictive variable in kisspeptin fertility outcomes isn't total dose. It's whether the peptide is administered as pulsatile stimulation or sustained elevation. GnRH neurons respond to kisspept…
Hypothalamic Amenorrhea (HA) Continuous IV infusion 0.01–0.04 nmol/kg/hour 8–12 weeks Resumption of menstrual cycles Pulsatile delivery matches endogenous KISS1 neuron firing. Most physiologic approach for HPG…
