The kidney plays a vital role in excretion by filtering waste products, excess water, and electrolytes from the blood to form urine. It helps maintain the body's overall balance of fluids and electrolytes by regulating their levels in the urine. Additionally, the kidney helps remove toxins and metabolic byproducts from the body, contributing to overall waste elimination.
Normally it comes out through the body's regular excretion process - kidneys, etc. During major withdrawals though, and if your dosage is high enough, it'll sweat out through your pores.

The major metabolic hormone in the body is insulin. It plays a crucial role in regulating blood sugar levels and promoting the uptake of glucose by cells for energy production. Insulin is primarily produced by the pancreas.
The major energy-carrying molecules of cells are adenosine triphosphate (ATP). ATP is produced during cellular respiration and carries energy in its chemical bonds that can be readily used by cells for various metabolic processes.
