GHRH is released from neurosecretory nerve terminals of these arcuate neurons, and is carried by the hypothalamo-hypophyseal portal system to the anterior pituitary gland, where it stimulates growth hormone (GH) secretion by stimulating the growth hormone-releasing hormone receptor.
These cells release the peptides growth hormone-releasing hormone (GHRH or somatocrinin) and growth hormone-inhibiting hormone (GHIH or somatostatin) into the hypophyseal portal venous blood surrounding the pituitary. GH release in the pituitary is primarily determined by the balance of these two peptides, which in turn is affected by many ...
Sermorelin acetate (INN Tooltip International Nonproprietary Name; brand names Geref, Gerel), also known as GHRH (1-29), is a peptide analogue of growth hormone-releasing hormone (GHRH) which is used as a diagnostic agent to assess growth hormone (GH) secretion for the purpose of diagnosing growth hormone deficiency.

Growth hormone secretagogues or GH secretagogues (GHSs) are a class of drugs which act as secretagogues (i.e., induce the secretion) of growth hormone (GH). [1] They include agonists of the ghrelin/growth hormone secretagogue receptor (GHSR), such as ghrelin (lenomorelin), pralmorelin (GHRP-2), GHRP-6, examorelin (hexarelin), ipamorelin, and ibutamoren (MK-677), [1] [2] and agonists of the ...
Growth hormone-releasing peptide 6 (GHRP-6) (developmental code name SKF-110679), also known as growth hormone-releasing hexapeptide, is one of several synthetic met-enkephalin analogues that include unnatural D-amino acids, were developed for their growth hormone-releasing activity and are called growth hormone secretagogues.
CJC-1295 may markedly increase plasma growth hormone (GH) and insulin-like growth factor 1 (IGF-1) levels in animals and humans. [1] [2] [3] [5] With a single injection, in human subjects, CJC-1295 DAC may increase plasma GH levels by 2- to 10-fold for 6 days or longer and plasma IGF-1 levels by 0.5- to 3-fold for 9 to 11 days.

Tesamorelin is the N-terminally modified compound based on 44 amino acids sequence of human GHRH. [3] This modified synthetic form is more potent and stable than the natural peptide. It is also more resistant to cleavage by the dipeptidyl aminopeptidase than human GHRH. [4]
