Pulsatile versus tonic GH release biology: Studies comparing the downstream biological consequences of pulsatile GH release (produced by short-acting GHRH analogues and GHRPs) versus tonic GH elevation (produced by long-acting GHRH-DAC variants or continuous GH infusion) established that pulsatile GH patterns are more potent drivers of hepatic IGF-1 production and anabolic GH signalling than equivalent total GH doses delivered continuously providing the physiological rationale for preserving pulsatile GH release characteristics in GH secretagogue research designs
