Pituitary Gland
The 'master gland' at the base of the brain that secretes growth hormone, ACTH, TSH and other downstream hormones.
Definition
The pituitary is a pea-sized gland at the base of the hypothalamus that coordinates endocrine output. Its anterior lobe secretes growth hormone, adrenocorticotropic hormone (ACTH), thyroid-stimulating hormone (TSH), prolactin and the gonadotropins; its posterior lobe releases oxytocin and vasopressin. GHRH analogs and GH secretagogues act at the anterior lobe's somatotroph cells.

Growth HormoneGH
A pituitary-secreted hormone that drives protein synthesis, fat metabolism and tissue repair — released in pulses, peaking at night.
MechanismGHRH AnalogGrowth-Hormone-Releasing Hormone Analog
A class of peptides that mimic growth-hormone-releasing hormone at the pituitary to trigger the body's own GH release — CJC-1295, Tesamorelin and Sermorelin.
