Ultimate Fighting Championship heavyweight Mohammed
Usman could not escape the investigation of the anti-doping
agents.
On Thursday, the UFC announced in a joint statement with drug-testing agency Combat Sports
Anti-Doping (CSAD) that Usman has been suspended after testing
positive for an exogenous source of testosterone. He was flagged on
Sept. 8, 2025, which resulted in his removal from his bout against
Valter
Walker at UFC Fight Night 261 in October of last year.
Additionally, Usman provided a false reason as to his failed test,
resulting in additional sanctions.

As a result of that test and his admission of past use of the
substance as well as BPC-157—an unapproved peptide designed to improve the recovery
process, Usman will be suspended until April 2028. Normally, a
fighter would receive a two-year sentence, but Usman added
“aggravating circumstances” by attempting to falsely claim its
source and his regular use. Thus, the CSAD issued a sentence of two
years and six months, since the heavyweight eventually owned up to
his usage.
Usman Ultimately Took Responsibility
The statement from CSAD reads as follows: “Combat Sports Anti-Doping (CSAD) announced today that Mohammed
Usman, of Coral Springs, Florida, has accepted a 2-year and
6-month period of ineligibility for violations of the UFC
Anti-Doping Policy (UFC ADP).
“Usman tested positive for the presence of testosterone, a
prohibited at all times substance in the class of Anabolic Agents
on the UFC prohibited list, from an out of competition sample
collected from him on September 8, 2025, in Coral Springs, Florida,
USA. Usman was previously removed from his scheduled bout in Rio de
Janeiro, Brazil, in October of last year due to the return of this
positive test days before the event. Usman ultimately admitted to
CSAD to the use of testosterone leading up to the Rio event, as
well as the previous use of testosterone and the prohibited at all
times peptide, BPC-157, earlier in 2025.
“While Usman ultimately took responsibility for the above details,
he did not do so in a timely fashion and not until CSAD confronted
him with evidence they had independently collected during a
detailed investigation of his use of these multiple prohibited
substances as well as his attempt to deceive CSAD with a false
explanation. Under the UFC ADP, if a UFC athlete uses multiple
substances like Usman did and engages in deceptive or obstructive
conduct to avoid the adjudication of an Anti-Doping Policy
Violation like he did, then aggravating circumstances are
determined to exist. While aggravating circumstances can double a
standard suspension, because Usman ultimately admitted to the
prohibited behavior, CSAD determined that a six-month addition to
the standard 2-year suspension for using these substances was
appropriate for these aggravating factors.
“Usman’s accepted suspension began on October 9, 2025, the day he
was notified of the positive test, removed from the Rio de Janeiro
card and provisionally suspended. The suspension will end on April
9, 2028.”
