CBP: Stanozolol, the Forbidden Shadow Affecting Professional Boxing
In the world of professional boxing, physical integrity, fairness, and natural performance are fundamental pillars.
However, sometimes the use of prohibited substances calls these values into question. One of the most closely monitored compounds is stanozolol, a synthetic anabolic steroid that has been officially banned by the World Anti-Doping Agency and all recognized boxing federations.
What is Stanozolol?
Stanozolol, known commercially as Winstrol, was developed in the 1960s and originally used medically to treat anemia and diseases that cause loss of body mass.
Why is it banned?
The main reason for its ban is clear: it artificially alters athletic performance. Furthermore, prolonged use can cause serious side effects such as:
• Liver damage.
• Severe hormonal changes.
• Increased risk of heart attacks and strokes.
• Psychological problems such as aggression, anxiety, and depression.
• In men, testicular atrophy; in women, masculinization.
Notable Cases and Consequences
Over the years, several boxers have tested positive for stanozolol, resulting in exemplary penalties, stripping of titles, multi-year suspensions, and invalidation of fights.
Doping sanctions vary depending on the organization and the repeat offense, but can range from a two-year suspension to a lifetime ban, affecting not only the boxer’s career but also his reputation.
Conclusion
The use of stanozolol and other prohibited substances is a sensitive issue in boxing. Despite increasingly strict controls, its use persists. Authorities and commissions insist on maintaining strict vigilance to protect not only the competitive spirit of the sport but also the health of boxers.
