It was recently put on the banned substances list, so your question is basically asking if he's willing to admit to doping. Many Russian athletes have been busted for using it regardless of its recent placement on the banned substances list

To add onto this, I don't think swimmers will ever actually stop improving.

We will find better techniques, and as the sport grows, people better suited for the sport genetically.
