The ITA reports that a sample collected during an in-competition testing mission on 4 October from Olaf Kepa, a Ju-Jitsu fighter from Poland, has returned an AAF¹ for the prohibited substances mentioned above.
Metandienone stenbolone, dehydrochloromethyl-testosterone (DHCMT) and drostanolone are prohibited under the 2025 WADA Prohibited List as S1.1 Anabolic Androgenic Steroids (AAS). They are prohibited at all times (in- and out-of-competition) and are classified as non-specified substances. These substances have potent muscle-building and strength-increasing properties.
Anastrozole is prohibited under the 2025 WADA Prohibited List as S4 Hormone and Metabolic Modulators. It is an aromatase inhibitor that reduces estrogen-related side effects of steroid use and helps maintain a higher testosterone-to-estrogen ratio. Anastrozole is a specified substance and is prohibited at all times (in- and out-of-competition).
GW1516 is prohibited under the 2025 WADA Prohibited List as S4.4 Metabolic Modulators. It is a peroxisome proliferated-activated receptor delta (PPARδ) agonist that activates fat metabolism pathways and improves endurance performance. GW1516 is a non-specified substance and is prohibited at all times (in- and out-of-competition).
Octodrine is prohibited under the 2025 WADA Prohibited List as S6.B Stimulants. It is a central nervous system stimulant that boosts alertness and energy by increasing dopamine and noradrenaline uptake. Octodrine is a specified substance and is prohibited in-competition only.
The athlete has been informed of the case and has the right to request the analysis of the B-sample.
If the B-sample analysis is requested and confirms the result of the A-sample, the case will be considered as a confirmed anti-doping rule violation. If the B-sample analysis is not requested, the case will also go ahead as a confirmed anti-doping rule violation. The athlete will have the opportunity to present his explanations for the result.
Further, in accordance with the World Anti-Doping Code and Article 7.4.1 of the JJIF Anti-Doping Rules, a mandatory provisional suspension has been imposed on the athlete. The athlete has the right to challenge the provisional suspension and ask for its lifting.
Pursuant to the JJIF’s delegation of parts of its anti-doping program to the ITA, the prosecution of the case is being handled entirely by the ITA. Given that the case is underway, there will be no further comments made.
¹ A report from a WADA-accredited laboratory that, consistent with the International Standard for Laboratories, establishes in a sample the presence of a prohibited substance or its metabolites or markers or evidence of the use of a prohibited method.
