This comparison does not assign a generated winner or score.
- Kisspeptin alone (1 µg/kg SC)
- 180–240%
- Minimal (<10%)
- +15–25
- 10–45 min (GnRH peak)
- Reproductive axis evaluation
- Sermorelin alone (1 µg/kg SC)
- Minimal (<5%)
- 50–90%
- +20–40
- 20–60 min (GH peak)
- Growth hormone deficiency assessment
- Simultaneous stack (both 1 µg/kg SC)
- 190–250%
- 60–100%
- +40–60
- Overlapping, suboptimal
- Convenience protocols
- Staggered stack (kisspeptin → 30 min → sermorelin)
- 210–280%
- 120–180%
- +75–110
- Sequential optimisation
- Advanced neuroendocrine research
- Pulsatile kisspeptin + single sermorelin
- 200–260% sustained
- 80–130% prolonged
- +85–120
- Extended (90–120 min)
- Physiologic pulsatility studies
- Bottom Line
- Staggered administration produces the highest hormone output and IGF-1 elevation. Simultaneous dosing is less effective but operationally simpler. Pulsatile protocols best mimic endogenous signaling but require multiple administrations.
