GHRH
Also: growth hormone-releasing hormone
In plain language
A brain hormone that tells the pituitary gland to release growth hormone.
Technical definition
A hypothalamic peptide that stimulates the synthesis and secretion of growth hormone from the anterior pituitary; analogs include sermorelin, tesamorelin, and the CJC-1295 backbone.
GHRH analogs work by amplifying the natural pathway that drives growth hormone release. Because they act upstream at the pituitary, they preserve the body’s normal pulsatile pattern of growth hormone secretion.
