The primary function of these peptides is the poweful stimulation of the pituitary gland encouraging it to produce more Growth Hormone which can cause the liver to secrete the hormone IGF-1, in laborotory animal tests, thius improved the ability to burn fat and build muscle. As GHRP-6 acts directly on the feedback loop which signals the inhibition of Growth Hormone release, it can re-stimulate the production of Growth Hormone.
