Browne told reporters on Wednesday he was shocked, disappointed and could not speculate on how he could have tested positive for the banned drug.
His team say privately they fear food contamination may have taken place in Chechnya as they were under armed guard throughout their stay in Grozny and ordered not to leave their accommodation without a bodyguard for safety reasons.
Plans are in place to have Browne's B sample analysed by the Las Vegas-based Voluntary Anti-Doping Association (VADA) and he is hopeful the matter can be resolved.
He says while he avoided drinking local water it was not feasible for him to bring in his own food as he was in the country for 12 days.
Browne says he will do everything to clear his name, but the decision was out of his hands.
Meanwhile, he will keep training for his next fight.
"I have no idea about the 'cleared' aspect of it ... I am confident where I stand, I am completely innocent and the team and everyone else has the right intentions with everything that's going," Browne said in Perth.
Well, y'know Three consecutive posts, each calling out someone he has some set against and just having a go (and it's pretty typical). There's a limit. And the chap is clearly incapable of understanding the difference between somber reflection and understatement. I have friends in the vicinity of where that shit kicked off, and I sure as hell wasn't downplaying the seriousness of the situation.
