Roberts has been issued with three anti-doping rules violations (ADRV) during his career. In 2017 he tested positive for probenecid, but a tribunal hearing found that he "ingested [the] prohibited substance without fault or negligence" after the source was deemed to have occurred after kissing his girlfriend and therefore received no sanctions from the United States Anti-Doping Agency (USADA). The World Anti-Doping Agency (WADA) challenged the decision, but a tribunal dismissed their appeal. In 2022, Roberts received a 16 month competition ban after testing positive for unintentional use of andarine and ostarine. In June 2024, Roberts received an eight-year competition ban after testing positive for ostarine and other prohibited substances. ==References==
