Growth Hormone Secretagoge
GHRP-6 is not an active fragment of growth hormone releasing hormone (GHRH). It is one of several synthetic met-enkephalin analogs that include unnatural D-amino acids that were developed for their growth hormone releasing activity and are called growth hormone secretagogues. GHRP-6 is a true hGH secretagogue. Which means it stimulates the body’s own secretion of hGH. hGH has been shown in studies to promote lean body mass and reduce adiposity (body fat). It is now known that this growth hormone releasing peptides are distinct from GHRH and do not act at the GHRH receptor, but instead act at the GH secretagogue receptor, now named the ghrelin receptor. It is for this reason (ghrelin like properties) patients being treated with GHRP-6 experience appetite stimulation.
