Well as funny as it may sound I believe that her team missed this, probably the fact about the rather long life cycle in the body of 2+ months.
I first heard that meldonium will be banned from Jan 1, 2016 only in mid October 2015. So I'm pretty sure that many many athletes missed this. Adding the rather long life cycle it means it's very likely.
Why are you such an apologist for them? If you heard about it in 10/2015, then she had to have heard about by at least then, and she should have gone off of it. She didn't and they should keep a better watch out for all the PEDs she is on. An airtight WATCH.
