The UCI has announced that Colombian rider Germán Darío Gómez Becerra has been notified of an adverse analytical finding for boldenone and one of its metabolites, following an out-of-competition sample collected on 28 December 2025.
Under the UCI Anti-Doping Rules, Gómez Becerra has been provisionally suspended. The UCI added that the rider has the right to request analysis of the B sample, and said it will not comment further while proceedings are ongoing.
Boldenone and its metabolites are listed as prohibited substances under class S1.1 (anabolic androgenic steroids) on the 2025 Prohibited List adopted by the UCI.
What happens next in the process
A provisional suspension is a standard step following an adverse analytical finding. The next procedural landmark is whether Gómez Becerra requests a B sample analysis. If the B sample is requested, it is used to confirm or overturn the initial laboratory finding from the A sample. Until the case is resolved, the UCI’s position is typically limited to process updates rather than commentary on circumstances or explanations.
The UCI also reiterated that operational activities within its anti-doping programme are delegated to the International Testing Agency, while results management and prosecution remain with the UCI.
Who Gómez Becerra is and where he races
Gómez Becerra, 26, has raced for the Polti structure across recent seasons, including Team Polti Kometa in 2024 and Team Polti VisitMalta in 2025 and 2026. Earlier in his career, he also rode for GW Shimano Sidermec and Colombia Tierra de Atletas GW Shimano, after coming through Colombian development teams.
In UCI-recorded results, he has two wins, both at the Under-23 national level in Colombia, including a time trial title and a road race title.
Away from results, he is also remembered by some fans for a widely shared moment from the 2019 World Road Championships in Yorkshire, when a puncture left him stranded and visibly distressed at the roadside before he was able to continue. It became a snapshot of how quickly a race can turn when support is limited, and luck runs out.
The key detail in the UCI statement
The UCI’s statement is narrowly focused on process: an adverse analytical finding, a provisional suspension, and the rider’s right to request the B sample analysis. There is no timeline given for the next update, and no further detail beyond the substance, the sample date, and the governing framework under which the case will proceed.
