"Insulin is a hormone that plays a crucial role in regulating blood sugar levels. The pancreas produces it, and its primary function is to help cells in the body absorb glucose from the bloodstream, which is then used for energy. In bodybuilding, insulin is often used as a performance-enhancing substance due to its anabolic effects. Insulin stimulates the uptake of amino acids and glucose into muscle cells, promoting muscle growth and repair [16]. However, the misuse of insulin can have serious health consequences. When insulin is used improperly or excessively, it can cause hypoglycemia, a dangerous condition characterized by low blood sugar levels. Hypoglycemia can cause dizziness, confusion, sweating, and even loss of consciousness. In severe cases, it can lead to seizures, coma, and even death [17,18].

"Another potential danger of insulin misuse is the development of insulin resistance, a condition where cells become less responsive to the effects of insulin. This can lead to elevated blood sugar levels and the development of type 2 diabetes [19]. In addition to these health risks, using insulin in bodybuilding is also illegal and prohibited by most sports organizations. Its use is considered doping and can result in disqualification, suspension, and other penalties. Therefore, it is important for athletes to understand the risks associated with insulin misuse and to avoid using it as a performance-enhancing substance [20]."
