About Ghrelin
Must be acylated at Ser3 (by GOAT enzyme) for GHSR-1a binding. Receptor activation in the pituitary stimulates GH release; hypothalamic action via NPY/AgRP neurons increases appetite and reduces energy expenditure.
About Hexarelin
Potent synthetic GHRP; strongest GH secretagogue in its class; also activates CD36 scavenger receptor for cardioprotective effects
