Final answer:
Synthetic androgen analogues known as anabolic steroids are used to promote muscle growth and are more stable than natural androgens like testosterone. Prolonged use can lead to serious health issues.
Step-by-step explanation:
Synthetic androgen analogues, called anabolic steroids, promote muscle growth. They have the same effects as androgens, which are male sex hormones like testosterone, but are more stable, meaning they are not metabolized as quickly.
Prolonged use of anabolic steroids can lead to physical and psychological problems. Health care providers can prescribe anabolic steroids to treat certain medical conditions, but athletes and bodybuilders sometimes misuse these drugs to enhance performance or physical appearance. This misuse can cause a range of adverse effects, including mood changes and increased aggression.
