A significant report published on July 8, 2026, by acclaimed journalist Michael S. Schmidt has sent ripples through the mixed martial arts community, alleging former two-division UFC champion Conor McGregor utilized banned performance-enhancing substances during his extended layoff. The report, citing anonymous sources, claims McGregor used anabolic steroids and Human Growth Hormone (HGH) following his severe tibia break in July 2021.

The Allegations Unveiled

According to Schmidt's findings, McGregor allegedly confessed to UFC officials that he continued the use of these substances because he simply 'liked the feeling.' This admission, if true, paints a complex picture of McGregor's rehabilitation and his journey back to the octagon. The timing of this report is particularly striking, emerging just days before 'The Notorious' is slated for his much-anticipated return at UFC 329.

McGregor's re-entry into the USADA testing pool occurred in October 2023, a mandatory step for any athlete returning to competition after a period of inactivity. Since then, he has been vocal about his commitment to clean sport, publicly stating that he has undergone 15 tests in 2026 alone in the lead-up to his comeback fight.

Implications for UFC 329 and Betting Markets

For bettors and fight fans alike, these allegations introduce an unforeseen layer of complexity to McGregor's upcoming bout. While the report focuses on usage during a recovery period, away from active competition, the psychological impact and public perception surrounding such claims can be profound. The narrative around McGregor’s physical condition and performance capability now faces intense scrutiny.

Savvy bettors will be closely monitoring how this developing story might influence the betting odds for UFC 329. Such high-profile controversies often lead to shifts in public sentiment, which in turn can sway betting lines. While we never invent specific odds, the general principle holds: uncertainty breeds volatility.

Understanding the potential impact of such allegations on a fighter's mentality and physical conditioning is crucial.

What's Next?

As UFC 329 draws nearer, all eyes will be on Conor McGregor and the fallout from this report. The MMA world awaits further statements from McGregor, the UFC, and USADA, as the sport grapples with another high-profile performance-enhancing drug allegation impacting one of its biggest stars.
