Suspended Indian wrestler Sumit Malik on Tuesday said he has no idea how a banned stimulant entered his body but admitted that he was on painkillers during the recent Olympic Qualifiers and had made a declaration about the medicines taken in the WADA form after the competition. The 2018 Commonwealth Games gold-medallist was handed a provisional suspension by the United World Wrestling (UWW) after a specified banned substance -- 5-methylhexan-2amine (1,4 dimethylpentylamine) -- was found in his sample. Malik had secured the 125kg category quota for the Tokyo Olympic during the Olympic Qualifiers, held in Sofia, Bulgaria, last month but was handed a suspension for failing his dope test during the same tournament.

"There was severe pain in my knee and I had taken painkillers Mobizox and Voveran. I had informed the officials about it. I have taken the same painkillers before also, I don't know how I tested positive," Malik told PTI. "UWW people have also informed me that the quantity of the substance is less than one per cent. It's merely 0.5 per cent. They have told me that a clear picture will be given to me in 3-4 days," he added. Sources says Malik's 'B' sample will be analysed either on June 29 or 30. While Malik asserted that he has taken only these two pain killers, AIIMS senior resident doctor Uditi Gupta said that none of them contains any stimulant. "Neither Mobizox nor Voveran contains any stimulant. It might be there in some other protein supplements he was taking. "Voveran is a single drug that contains only diclofenac, which is a painkiller while Mobizox is a combination drug which is a painkiller and a muscle relaxant but there is no stimulant in it," Gupta said.
