Growth hormone (GH) plays a critical role in growth & development, as well as a variety of other bodily functions such as immunity, bone health, and muscle development. Certain supplements aim to elevate growth hormone – particularly in older individuals because GH levels decrease as we age – as a way to support overall health. This glossary lists and defines some of the main terms and concepts relevant to growth hormone and growth hormone supplements.
A group of organic compounds involved in many important biological processes. They are best recognized as the building blocks of proteins. Several amino acids, such as GABA, have been found to stimulate growth hormone release, although their use as GH boosters is not recommended in athletes.
Any compound used to stimulate or regulate the development of male characteristics. Shifts in androgen levels can affect the status of growth hormone in the body. Testosterone, dihydrotestosterone, and dehydroepiandrosterone are the most common examples.
Bone density, or bone mineral density (BMD), is the content of minerals—particularly calcium and phosphorus—present in a bone. Low bone density is linked to an increased risk of fractures. Human growth hormone is essential for maintaining healthy bone density.
