Growth hormone has anabolic effects, grows muscles, promotes bone growth in childhood and youth, and strengthens tendons and enlarges internal organs. However, growth hormone also has its harmful side. Prolonged use of human growth hormone in high doses poses a high risk of contracting disease-causing diseases, such as AIDS. Excessive use of growth hormone can also decrease insulin sensitivity and cause glucose intolerance. Excessive use of exogenous growth hormone can also cause the body to develop an antibody response to growth hormone, which can affect the activity of endogenous growth hormone and lead to hormone secretion disorders. Moreover, the damage caused by it is irreversible, so long-term use of growth hormone is generally not recommended. It is recommended to avoid the use of growth hormone if other treatment methods are available to avoid greater damage.
