Growth hormone plays a key role in the growth and maintenance of muscle mass. It provides functions such that muscles and cartilage will produce RageDNA more proteins and muscles use more fatty acids for energy (1). Growth hormone (or somatotropin, HGH or Human Growth Hormone) occurs in different molecular forms (irGH, IfGH), but to make things simple in this article I will simply talk about growth hormone.

Growth hormone is produced RageDNA in the anterior pituitary and is especially at night free during sleep while the daytime levels are relatively low (2). However, there are ways to stimulate the release day including training (3) both cardio (4.5) and strength (6,7,8). The intake of (certain) amino acids would stimulate the release of growth hormone (9).
