A 191-amino acid peptide hormone secreted by the anterior pituitary gland that regulates growth, body composition, metabolism, and tissue repair.
Growth hormone (GH), also known as somatotropin, is a 191-amino acid single-chain polypeptide synthesised and secreted by somatotroph cells in the anterior pituitary gland. GH secretion follows a pulsatile pattern regulated by the opposing actions of GHRH (stimulatory) and somatostatin (inhibitory), with the largest pulses occurring during deep slow-wave sleep. GH acts both directly and indirectly via insulin-like growth factor 1 (IGF-1), which is produced primarily in the liver in response to GH stimulation. Its physiological effects include stimulating linear bone growth, promoting lean body mass accretion, enhancing lipolysis (fat breakdown), supporting immune function, and facilitating tissue repair and regeneration. GH levels decline progressively with age (somatopause), driving research interest in GH secretagogue peptides like CJC-1295 and Ipamorelin that stimulate endogenous GH release through natural pituitary pathways.
A synthetic 29-amino acid analogue of growth hormone-releasing hormone (GHRH) that stimulates sustained growth hormone elevation from the pituitary gland.
A selective pentapeptide growth hormone secretagogue that stimulates GH release via the ghrelin receptor with minimal effects on cortisol and prolactin.
Growth Hormone-Releasing Hormone, a 44-amino acid peptide produced in the hypothalamus that stimulates growth hormone synthesis and secretion from the pituitary.
A pea-sized endocrine gland at the base of the brain that produces growth hormone, ACTH, TSH, and other hormones regulating crucial body functions.
