No they are not steroids. They are made up of proteins

I.G.H. stands for Insulin-like Growth Factor, a hormone that plays a role in cell growth and development in the body. It is similar in structure to insulin and is produced mainly by the liver in response to stimulation by growth hormone.
Growth hormone stimulates the release of insulin-like growth factor 1 (IGF-1) into the blood.
Insulin-like growth factor (IGF) is a hormone that plays a role in regulating cell growth and division. In diabetes, high levels of IGF can lead to insulin resistance, where the body's cells do not respond effectively to insulin. This can contribute to the development and progression of diabetes by causing elevated blood sugar levels and potentially leading to complications such as cardiovascular disease and kidney damage.
There are multiple human growth factors, with over 50 identified so far. Some common ones include insulin-like growth factor (IGF), epidermal growth factor (EGF), platelet-derived growth factor (PDGF), and fibroblast growth factor (FGF). These growth factors play essential roles in processes like cell growth, proliferation, and differentiation.

The six hormones primarily affecting growth are growth hormone (GH), insulin-like growth factor 1 (IGF-1), thyroid hormones (T3 and T4), insulin, testosterone, and estrogen. These hormones play key roles in regulating growth and development during different stages of life.

Somatotropin, also known as growth hormone, can increase metabolism by enhancing the breakdown of fats for energy, promoting protein synthesis, and supporting the growth and repair of tissues. It can also stimulate the release of insulin-like growth factor 1 (IGF-1), which plays a role in regulating metabolism and energy utilization.
Liver cells respond to growth hormones by releasing insulin-like growth factor 1 (IGF-1). This hormone plays a key role in promoting cell growth, proliferation, and differentiation, especially during times of growth and development.
