The term MUSCLE-BUILDING DRUG can be summarized as STEROID, a 7 letter word. Steroids are synthetic drugs that mimic the effects of hormones naturally produced in the body. They are commonly used to increase muscle mass and strength, as well as to reduce body fat. Steroids are also used to treat certain medical conditions, such as delayed puberty and some types of cancer. However, long-term use of steroids can lead to serious health problems, including liver damage, high blood pressure, and increased risk of heart attack or stroke.
