Jon Jones Declares He Never Took Steroids, Cites Tainted Supplement
Retired UFC heavyweight champion Jon Jones has repeatedly denied ever using steroids, saying the trace substances found in his system originated from contaminated dietary supplements that have no performance‑enhancing effect. In an interview with ALF Global, Jones explained that the amount detected was so minute that only costly scientific analysis could identify it.
Arbitrators later cleared him in the turinabol case, removing his name from the list of violations, though the 2017 no‑contest result against Daniel Cormier remains. Jones previously tested positive for clomiphene and letrozole in 2016, which forced the cancellation of his UFC 200 rematch with Cormier, and for turinabol in 2017, which overturned his UFC 214 win. Minor detections before UFC 232 and UFC 235 were deemed residual and no further action was taken. Jones announced his retirement in June 2025 but hinted he might return if the right opportunity arises.
In a separate interview, Jones claimed that the rivalry with Cormier generated significant earnings, a statement Cormier publicly rejected, emphasizing that any financial benefit came from the existence of a rivalry, not its fabrication.
