Core Event
In July 2026, UFC champion Conor McGregor publicly defended his use of anabolic steroids and human growth hormone after a report revealed he had taken the substances following a severe leg fracture. The disclosure, made public last month, sparked renewed scrutiny of McGregor’s compliance with the sport’s anti-doping rules.
Background & Context
McGregor opted out of the UFC’s drug-testing program for more than two years, a period during which he was able to use prohibited performance-enhancing drugs without facing suspension. UFC testing resumed in October 2023, at which point his drug use became subject to scrutiny. The athlete’s broken leg, described as “badly broken,” required extensive medical treatment, which McGregor and his medical team have framed as the rationale for the drug regimen.
Official Statements & Responses
McGregor, the UFC, and McGregor’s surgeon have characterized the drug use as “medically necessary” to ensure proper healing of the fractured leg. Their position emphasizes that the substances were administered under professional supervision to aid recovery, rather than to gain a competitive edge.
Criticism & Opposition
Anti-doping experts argue that McGregor exploited a regulatory loophole by remaining off the testing roster while using banned substances. Two sources with knowledge of the matter assert that McGregor continued the steroid and hormone regimen after his leg had healed, citing his own admission that he liked the “energy” and feeling the drugs provided. Critics contend that such continued use undermines the integrity of UFC competition and violates the spirit of anti-doping policies.
Conflicting Reports & Gaps
The precise duration of McGregor’s drug use remains unclear. While the report confirms he began testing again in October 2023, it does not specify how long the anabolic steroids and growth hormone were administered after his injury healed. Further investigation is needed to determine whether any additional violations occurred during the post-recovery period.
