There ofc for Usyk really noy easy might to hide anything.
Ofc I don't trust tests done in Ukr for ukr boxer...
However all most notable am and pro fights Usyk had did on foreign soil and had been tested in these events with a glance.
For example in 2008 th he he had competed in 3 very high level torunaments in Bulgaria, Russia and U.K ....
Definitely they does have their own high level ams boxers and for them 0 reasons to babysit some concurrent with testing. Pretty opposite: they with a glance had popped up if something wrong.
2009 th was Italy, unlike with pros they does have very good high level am boxers ...and normal premials for medals... ofc testing and if concurrent isn't clean there 0 mercy...
2010, 2011, 2012 he too had been tested in foreign countries. Incl for Games 2012.
Interesting that in pros he did all his notable fights on foreign soil and mainly vs their tickets sellers..../ so obiviously that they had tested him with vigor and carefully monitored hands wraps, gloves etc....especially if your tickets seller isn't undefeateated anymore after fight vs Usyk...
High level pro boxers are investments objects with intent to earn money cos they are highly ranked, it is possible to sell tickets with them on fight cards, to earn from ad deals and endorsement stuff.
So ofc you prefer that fight will be in your country and then....IF.... it is easy to test, claim and so on...
