GHRHR
GHRHR GHRH receptor — the molecular target that 3 compounds in the wiki act on.
In one line: The pituitary's "release growth hormone" receptor.
GHRHR is the receptor on your pituitary gland that responds to your brain's natural "release growth hormone" signal. A family of peptides — sermorelin, CJC-1295, and the FDA-approved tesamorelin — are copies of that signal. They press this receptor to coax your pituitary into releasing more growth hormone in its natural, pulsing pattern.
Paired with a ghrelin-type peptide (which works through a different receptor), the two produce a bigger, more natural growth-hormone pulse than either alone — which is why "CJC-1295 + ipamorelin" is such a common combination.
Tesamorelin is the one member with real FDA approval, uniquely proven to shrink deep belly fat.
