BTW, Meldonium is not a beta blocker. Here is a list and Meldonium is not there (use Google translate):

Препарат Кардиоселективность Внутренняя симпатомиметическая активность Липофильность
Ацебутолол + + ++
Атенолол ++ ? ?
Бисопролол ++ 0 ++
Карведилол ? 0 ++
Лабеталол ? + +++
Метопролол ++ ? +++
Надолол ? ? ?

Пиндолол ? +++ ++
Пропранолол ? ? +++
Целипролол ++ + ?

^ That's an official list of beta blockers used in the Russian medicine. Meldonium does not block adrenaline receptors, so it's not a beta blocker and it's not a steroid drug. So why it's considered as a doping?
