What factor could indicate that someone is using steroids based on their physical appearance?

The presence of above normal gains in muscle mass is a strong indicator of potential steroid use. Anabolic steroids are synthetic derivatives of testosterone that are often used to promote muscle growth and enhance athletic performance. When individuals use these substances, they may experience accelerated increases in muscle size and strength that far exceed typical training outcomes.

In a fitness context, athletes and bodybuilders strive for significant, progressive muscle development, but there are natural limits to how much muscle can be gained through training, diet, and genetics over a given period. When someone exhibits an unusually rapid increase in their muscle mass, it may suggest the influence of steroids, particularly if these gains occur despite a consistent and relatively unremarkable training regimen.

This characteristic can be a red flag, especially when it is accompanied by other signs of steroid use, such as changes in physical appearance, mood swings, or other physiological effects. Thus, identifying abnormal muscular development is an important aspect of recognizing possible steroid use in individuals.
