USADA announced today that Karl Moore, of the United Kingdom, has accepted the maximum one-year sanction for a violation of the Professional Fighters League (PFL) Anti-Doping Policy.
Moore, 33, tested positive for recombinant erythropoietin (rEPO) as the result of an out-of-competition sample collected on April 9, 2025. rEPO is prohibited at all times in the class of Peptide Hormones, Growth Factors, Related Substances, and Mimetics under the PFL Anti-Doping Policy (ADP) and PFL Prohibited List.
Under Section 10.2 of the current version of the PFL ADP, the default period of ineligibility for the use of a prohibited substance is six months but can be increased up to a year in certain circumstances. Here, Moore received a one-year period of ineligibility because his reckless conduct—injecting an unlabeled drug that did not belong to him—led to his positive test. Moore’s one-year period of ineligibility began on April 9, 2025, the date his positive sample was collected.
USADA conducts a year-round, independent anti-doping program for PFL athletes. USADA is an independent, non-profit, non-governmental agency whose sole mission is to stand with athletes to champion their right to clean sport, inspire true and healthy sport, and promote the integrity of sport. In an effort to aid PFL athletes, as well as their support team members, in understanding the rules applicable to them, USADA provides comprehensive instruction on the PFL Anti-Doping Program webpage regarding the testing process and prohibited substances, how to obtain permission to use a necessary medication, and the risks and dangers of taking supplements, as well as performance-enhancing and recreational drugs.
In addition, the agency manages a drug reference hotline, Global Drug Reference Online, conducts educational sessions, and proactively distributes a multitude of educational materials.
USADA makes available a number of ways to report the abuse of performance-enhancing drugs in sport in an effort to protect clean athletes and promote clean competition. Any tip can be reported using the USADA Play Clean Tip Center.
