Dr Kiel quickly reviews and explains Human Growth Hormone or HGH and the health effects on your body.
MORE TESTOSTERONE KNOWLEDGE
This playlist covers things like testosterone and other androgens, DHEA (Dehydroepiandrosterone), insulin like growth factor (igf-1, igf 1), and human growth hormone (hgh). The emphasis is understanding these hormones and ways to promote them naturally.

This peptide hormone, also known as somatotropin, human growth hormone or HGH, is a physiologically active hormone that has a significant role in multiple processes of the human body.
Growth hormone synthesis, production and regulation occurs in the hypothalamus-pituitary axis. These two glands, located in the brain, are responsible for a wide variety of hormone regulation that includes thyroid function, reproductive hormones such as estrogen and testosterone, adrenaline, dopamine, and others in addition to growth hormone. The regulatory process is somewhat complex and has an entire medical specialty dedicated to it known as endocrinology, so I won’t dive any deeper into that discussion but I would encourage you to look it up if you want to know more.
This is an anabolic hormone; in other words it ‘promotes growth’. While this includes skeletal muscle, it’s certainly not limited to it. It’s worth noting that it is not androgenic, as opposed to testosterone, meaning it doesn’t promote male sex characteristics such as facial hair and deeper voice.
The most prominent effect of this hormone is that it promotes bone growth and is the primary hormone responsible for growing to an adult size. In children, it’s largely responsible for determining height, and is modulated by several mechanisms. Secretion peaks during puberty, where the most bone growth occurs, and then declines with age (like most hormones). Along with bone growth, it promotes bone mineralization and calcium retention.
Other functions include:
Skeletal muscle proteins synthesis, specifically sarcomere hypertrophy
Increase in lean body mass
Fat breakdown (lipolysis)
Protein synthesis elsewhere (not just muscle)
Decrease cellular uptake of glucose
Increased glucose synthesis (gluconeogenesis)
Release of insulin-like growth factor 1 (will discuss separately)
Growth of other organs
Immune system stimulation
Promotes thyroid activity
