Adults can experience a deficiency in growth hormone, and the health effects of this deficiency can be profound.

Adults will experience a GH deficiency if their pituitary gland is not secreting an appropriate quantity of GH into the blood stream, or if through surgery or medical treatment, the pituitary is absent or underperforming.

The pituitary is a vital gland, and is often named "the master gland" as the hormone secretions from the pituitary are responsible for the regulation and control of a number of different glands in the body.

If an adult presents with an underperforming pituitary gland, it will be necessary to supplement the levels of the endogenous hormones with medical hormone supplements.

One of the most important supplements in the treatment of a pituitary condition is supplementary growth hormone GH.
