God created us in His own Image. Every part of us has a vital purpose. Injecting anything into the human body is unwise. Nothing is ever truly sterilized and to assume otherwise is naivety. The human skin is an organ and not designed to be pierced or ripped open. It isn't a pin cushion. In fact, it plays a key role of excretory functionality eliminating toxins from the body. To inject toxins into the body that undermine the body's immune system is crazy.
