Mechanism Comparison Shared Pathway Both peptides activate GHSR-1a on pituitary somatotrophs, triggering: GHSR-1a Gq/11 PLC IP + DAG intracellular Ca release PKC activation Ca influx GH vesicle exocytosis This is fundamentally different from how GHRH analogs (CJC-1295, Sermorelin) work (GHRHR Gs cAMP PKA), which is why combining either GHRP with a GHRH analog produces synergistic GH release (Veldhuis et al., 2009)
