Which of the following drugs is typically not used for enhancing athletic performance?

Tylenol, also known as acetaminophen, is a medication primarily used to relieve pain and reduce fever. It is a common over-the-counter drug that does not possess properties that would enhance athletic performance. Unlike substances such as human growth hormone and anabolic steroids, which can be misused in sports for their muscle-building and recovery benefits, Tylenol does not have any ergogenic effects or provide a competitive advantage in athletic settings.

Human growth hormone is often abused to increase muscle mass and improve recovery times, while anabolic steroids are notorious for their performance-enhancing capabilities, promoting muscle growth and strength. Cocaine is a stimulant that can increase alertness and energy but is illegal and harmful, and its use is banned in athletic competition. In contrast, due to its intended use and profile, Tylenol does not fit into the category of substances typically used to enhance athletic performance.
