- Studying endogenous GH axis regulation: Sermorelin is the appropriate tool — it probes the pituitary’s responsiveness and the integrity of the GHRH/GH/somatostatin feedback loop. GH stimulation tests using sermorelin diagnose pituitary GH reserve.
- Studying supraphysiological GH/IGF-1 effects: rhGH is the appropriate tool — it delivers controlled doses of GH independent of pituitary function, allowing precise manipulation of GH and IGF-1 levels without HPG axis variability.
- GH deficiency models: Both are relevant but answer different questions. rhGH replacement directly replaces the missing hormone. Sermorelin tests whether the pituitary has residual secretory capacity — relevant for partial GH deficiency models.
- Ageing and GH decline research: Sermorelin is particularly relevant for studying age-related GH decline, where the problem is reduced GHRH drive to a still-functional pituitary rather than pituitary failure per se. Sermorelin can restore GH pulsatility in aged animals where hypothalamic GHRH tone is reduced — a more physiologically accurate intervention than rhGH replacement in this context.
