原先帖子是根据：Essentially, trimetazidine has been reclassified and downgraded. As of January 1, it will not be on the banned stimulant list.（https://www.swimmingworldmagazine.com/news/sun-yang-doping-case/）。有朋友指出世界反兴奋剂组织的禁药名单上仍然有它： http://www.usada.org/substances/prohibited-list/athlete-guide/

“刚到网上逛了一圈，看到网评多是谩骂，我认为最重要的是澄清事实真相。以下是我的留言，供大家参考。希望朋友们有机会也到网上留言，帮助大家了解事情的原委：
The fact is that Trimetazidine, which Sun Yang took for justifiably medicinal purposes in 2014, is no longer banned by FINA, even in-competition. It is deemed not performance enhancing. It was on the list only for a short period of about one year. So even if Sun Yang took the med today, it would have been entirely legal. It is really not fair to label Sun Yang doping based on this.”
