The rider was suspended by the team, after a minute amount of Chlortalidone was found in his urine during an out-of-competition control on 14 June 2023. NADA and WADA both concluded that it was plausible that Hessmann had taken a contaminated medicine such as paracetamol, ibuprofen or naproxen. Earlier, German prosecutors therefore dismissed the case. In June 2024 NADA suspended the rider for four months, with a retroactive effect of three months, allowing him to return to action at the end of July. But WADA appealed, after which the rider and WADA reached a settlement to remain suspended until 14 March 2025.

Michel Hessmann will therefore no longer compete for the team.
