Pharmacodynamic studies demonstrate dose-dependent growth hormone elevation, with peak GH concentrations typically occurring 30-45 minutes post-administration and returning toward baseline within 3-4 hours, as documented in clinical pharmacology research (Gobburu et al., 1999)

The elevation in cAMP also stimulates protein kinase A which phosphorylates and activates the transcription factor CREB (cAMP response element binding protein), which then stimulates de novo GH production via transcription of the GH1 gene as well as increasing transcription of the GHRH receptor gene as part of a short positive feedback loop To summarize all of this in one sentence GHRH is responsible for both the production and secretion of growth hormone

Testosterone and progesterone, but not estradiol, stimulate muscle protein synthesis in postmenopausal women
