What is the primary concern with athletes using pro-hormones?

The primary concern with athletes using pro-hormones revolves around their potential to cause severe hormonal imbalances. Pro-hormones are compounds that the body can convert into hormones, but when taken in excess or without proper medical supervision, they can disrupt the body's natural hormone production and regulation. This imbalance can lead to a variety of health issues, including but not limited to mood swings, altered libido, changes in body composition, and an increased risk of cardiovascular problems.

While legality is a consideration, pro-hormones being illegal is not the main concern regarding their impact on athletes’ health. Effectiveness can also vary and is subjective; some athletes may argue they experience benefits. Cost might be a practical issue for some, but it doesn’t pose a direct health threat in the way that hormonal imbalances do. Understanding the risks associated with hormonal health is crucial for athletes who are considering using these substances.
