On Tuesday the Internationale Cycling Union announced the provisional suspension of 24 year-old Colombian German Dario Gomez (POLTI-VISIT MALTA) after he allegedly returned a positive out-of-competition anti-doping test result for the banned Anabolic-Androgenic Steroid Boldenone on 28 December 2025..

Gomez is a former Pan American Junior Time Trial Champion who gained notoriety for his tearful display of emotion at the 2019 World Championship when the junior rider flatted and fell out of contention.

Boldenone, a derivative of Testosterone, is a veterinary injectable used primarily to increase weight, improve coat condition and enhance muscle in horses. It has been used illegally in the sport of horse racing. The United States Food and Drug Administration has not approved it for use in humans for any reason and it is banned for use in horses competing in Olympic and Paralympic events.

Several other Boldenone anti-doping cases have surfaced recently, including Saudi Arabian amateur athlete Abdulrahman Alghamdi and 2025 Italian Masters M60-64 National Road Champion Lido Fogli.

Boldenone can occur in minute, naturally occurring amounts in humans, but is generally only considered a doping substance when found in significant concentrations in athletes. 

Note: Provisionally suspended athletes are presumed innocent until they have an opportunity to present their case in court and a verdict is issued, but in the meantime they are prohibited from participating in sport in any capacity.
