Braun and Singerman each have a long history in bodybuilding. Singerman, from New Orleans, started hitting the gym when he was 13 and kept working out, even through a cocaine and heroin habit he picked up after dropping out of high school. At 27 he witnessed a friend overdose and die, so he got clean and doubled down at the gym. In 2005, he got a job as a personal trainer and started writing thousands of posts on bodybuilding message boards and eventually became marketing director for Ironmag Labs, a supplements company owned by businessman Robert Dimaggio, who had become notorious for selling sketchy supplements. Singerman convinced Dimaggio to bring on Braun, whom he'd met at a bodybuilding competition, as the company's top sponsored athlete.
Technically speaking, BALCO is extinct, but Victor Conte is a free man and still running a business called "Scientific Nutrition for Advanced Conditioning" or "SNAC." After serving a four-month prison sentence prior to pleading guilty in 2005, he now sells various supplements and vitamins. Patrick Arnold and Greg Anderson each served a three-month jail sentence after pleading guilty with Anderson serving an additional three-month house arrest sentence. Recently Anderson was incarcerated again after being found in contempt of court for refusing to testify about Barry Bonds and Gary Sheffield’s use of banned steroids.  BALCO is not completely dead however; on the SNAC website, Conte has BALCO apparel for sale. 
My point is, we can’t have a situation where one athlete is “wonderwoman” or “super man” and the other other is a doper based purely on performance. Given that the best predictor of the response and suspicion is a line of latitude and longitude, I think we need to be a little more nuanced in the discussion. And yes, the context matters – it’s a Chinese world record, so dodgy, and Ayana trains in a place not known for stringency in anti-doping. Those factors make me equally suspicious. When Lord Coe told us all that he hoped we could believe what we saw in Rio, I don’t think he could see that coming from the first track final of the week’s athletics!
