- Sermorelin (GHRH(1-29)NH₂) and exogenous recombinant human growth hormone (rhGH, somatropin) are both used in GH-axis research but act at fundamentally different levels of the axis: Sermorelin stimulates endogenous GH secretion from the pituitary, while rhGH bypasses pituitary regulation entirely to directly activate GHR on target tissues. This comparison is mechanistically distinct from Sermorelin vs HGH post (ID 77049, which covers the clinical comparison broadly), Sermorelin longevity post (ID 77085), Sermorelin cardiovascular post (ID 77107), and the GH secretagogue hub (ID 77059) — this comparison focuses specifically on the mechanistic research differences between axis stimulation and receptor-level GH administration, what each reveals and conceals about GH biology, and the specific in vivo and in vitro research design implications of choosing one over the other.
