Best Kisspeptin Dosage LH Release 2026: Route, Dose, and Protocol Comparison
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 nmol/kg Subcutaneous Bolus 0.5–3.0 90–120 minutes 2.
This comparison does not assign a generated winner or score.
- 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 nmol/kg
- Subcutaneous Bolus
- 0.5–3.0
- 90–120 minutes
- 2.0–3.5×
- 3–4 hours
- Requires 2–4× higher dose than IV for equivalent effect; absorption variability increases inter-subject response spread; practical for repeat-dose studies where IV access is limiting
- IV Pulsatile (every 75–90 min)
- 0.1–0.3 per pulse
- Sustained pulsatility
- 1.5–2.5× per pulse
- Duration of infusion protocol
- Mimics physiological LH pulsatility; avoids GnRH receptor desensitisation; requires programmable infusion pump; best for multi-hour gonadotropin drive studies
- Continuous IV Infusion
- 0.5–1.5 total over 6 hours
- Initial peak at 60 min, then decline
- 3.0× initially, then suppression
- LH suppression after 4–6 hours
- Paradoxical suppression due to receptor desensitisation; not suitable for sustained LH elevation; useful only for receptor occupancy or desensitisation mechanism studies
