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 PEG-MGF
Pegylated form of MGF; activates muscle stem cells (satellite cells) to repair and regenerate muscle tissue after damage
