Combat Sports Anti-Doping (CSAD), the organization overseeing the UFC’s anti-doping program, just announced that they have suspended another fighter for drug violations.
This time it’s UFC women’s flyweight Maryna Moroz, who is 6-6 in the promotion and currently on a three fight losing streak. “The Iron Lady” hasn’t fought since a March 2024 loss to Joanne Wood, but was still being tested on June 25 and July 16, 2025. That’s when she popped positive for meldonium.
According to Moroz, the whole thing was due to a doctor prescribing her the drug without realizing she was being drug tested as a UFC athlete.
“Moroz provided medical documentation that she was under the care of a licensed physician who was treating her reported medical symptoms with meldonium,” the CSAD statement on UFC’s website read. “ However, Moroz did not tell her physician that she was a drug tested athlete, did not check with UFC-provided resources about the prohibited status of meldonium and she did not submit an application for a therapeutic use exemption (TUE) to seek permission to use the otherwise prohibited substance for medical reasons.”
CSAD does seem to believe Moroz’s drug test failure was more of a mistake than a nefarious attempt to dope. Between that and “complete cooperation” from the flyweight, they’ve shortened her suspension from 2 years to 1. She’ll be eligible to compete again in July 2026.
The post-USADA doping program hasn’t caught a ton of outright cheaters red handed, and those testing positive tend to be lesser known athletes. The program also seems to be more lenient than USADA’s. UFC heavyweight Alvin Hines was suspended in August after testing positive for Drostanolone and testosterone metabolites but had his suspension knocked down to 1 year after CSAD concluded that he only used steroids before signing with the UFC.
Contender Series signee Danylo Voievodkin was not so lucky. He tested positive for meldonium and had no excuse (or lawyer) to explain why. He was suspended for two years.
Those are the only three UFC fighters we know of that have tested positive this year. CSAD only announces failed drug tests after cases have been resolved and punishment or exoneration has been decided.
