Fresh claims come to light in Simona HALEP doping scandal surrounding concentration of Roxudustat in positive sample
Tennis News
While Simona Halep returned to the court last week after her doping ban was reduced from four years to nine months, new claims have since come to light from tennis journalist, David Walsh about the amount of Roxudustat needed to even flag up a positive sample.
The ITIA (International Tennis Integrity Agency) handed Halep a four year ban in September 2023 after she tested positive for the substance during the 2022 US Open. She denied consuming the substance intentionally and maintained innocence with the ruling challenged in the Court of Arbitration for Sport (CAS). She managed to get her ban reduced on appeal and was back on the court within a week.

But Walsh has put out an article in The Times with snippets shared by fellow journalist, Jannik Schneider claiming that CAS has overlooked major details regarding the concentration of Roxudustat with a huge amount needed to even flag it up on a sample. Dr Eichner who is president of the Salt Lake City laboratory and an expert in pharmacokinetics based his results on two scenarios with the highest level of Roxudustat and the lowest level. For the second, he used the average.
According to the first scenario, the conclusion was that the player would have to ingest more than 50 times the recommended 10g daily serving to produce a positive test. Under the second scenario, it gets blown wider with Eichner stating that Halep would need to ingest 5,000 times the amount to produce the concentration found in her sample which tested positive in August 2022. According to the conclusion made, CAS has ignored the pharmacokinetics or did not understand them and Walsh who titled his article Why return of Simona Halep gives me little confidence in fight against doping, he shares this as the reason why.
"To be fair this is an easy mistake to make. When I take my multivitamin tablet in the morning I sometimes accidentally take 4,999 more. Could happen to anyone," one tennis fan wrote in response to the tweet by Schneider.
"Completely agree, I was hoping Halep would be cleared using evidence, but zero evidence was presented. CAS used “balance of probability” as the main reason to reduce the sentence, that is very ambiguous, it means they are not 100% sure that she did it on purpose just that," another wrote.
"That may be described as: she's not a nobody she's Halep a nobody would get a lifetime ban," another concluded.

- One step by another step -- WTA continues to 'lose the plot'. Too many hi-tech microphones being installed at most venues!!! Remove them (especially those along the hallways, sidewalks, and pathways throughout the venues. Not to mention (most of all) remove the mic's from the Players/Coaches Box.
mandoist06-11-2026 - Enough of her bullshit. Go marry someone.
mandoist06-11-2026 - Don't you just love this young lady!? We fans often expect athletes to be supermen and superwomen, often forgetting that they WILL GET TIRED! I love Alex's perspective. Tiredness for an athlete should never be viewed as a negative, especially if you are healthy, taking care of your body and mental health and putting in the work. What a mature perspective. Good for you, Alex!Rapunzel05-11-2026
- Jess is absolutely correct! But the disrespect is a trait I have noticed in most of the Russian players. Mirra is good but very immature and lacks humility. Conceivable needs to get a handle on that!Rapunzel05-11-2026
- Having spent weeks and weeks through the years on tour, I can say with confidence that Conchita was (is) one of the very few who realize the surprising level of maturity (and sometimes lack of) which Mirra seems to have developed in such a demanding adult world of Pro-Tennis. While at the same time reminding herself (Conchita, that is) that Mirra is still young and developing mentally and physically. The general public may forget at times, or not at all realize, these modern era young athletes do not have a 'normal' Youth. It's a major sacrifice, among countless sacrifices, these athletes must make. People who blow-off that fact are ignorant and unfair when they blurt out, "They choose fame so they have to put up with the intrusions on their lives". No, they do not.
mandoist05-11-2026 - Okay... someone with a camera was EAVESDROPPING on a private conversation. Shouldn't that be the point of discussion here? Regardless of the sensationalist crap by media, Pegula (and anyone) has a right to an opinion. There used to be an expectation that private conversations were respected, regardless of 'stardom' and whatever other defensive excuses media tries to shove in our faces. Boo-hoo if feelings are hurt. BTW: Having been employed at various tourney venues, etc., I can't tell you how nasty and offensive players can be when discussing their opponents and colleagues... in "private". Well, I could, but won't. I also challenge anyone to deny what Jessica said is false.

Bad enough the NHL allows Ovachenko (a Putin Supporter and Campaigner) to live and play in the USA. Let's not forget the STATE SPONSORED RUSSIAN DOPING PROGRAMS still in effect today.
mandoist31-10-2026 - Osaka's mental state apparently does not allow her to reach any more Quarter Finals? I mean, she doesn't really have the time for tennis with all the pre-planning that must go into her 12 year-old "fashion" goals.
