ive just watched the two videos
Video 1:
The usada rep is on some sort of intercom system and Nick is like "i want to go to bed, ive just got in, i want to go to sleep, come back in 6 hours"
The rep repeatedly tells him over the intercom "if you dont provide a sample now you are liable to a 2 year suspension"
Nicks like "a what, come back in about 5 or 6 hours, whats the problem"
Usada rep "thats not acceptable nick, if you refuse to provide a sample you an be suspended for 2 years"
Nick " well what about tomorrow, ive been out all night, I have shit to do this week, i wanna wake up like 2pm,"
Usada "well you need to tell your agent you refused a visit"
Nick "no you call my fucking agent"
Video 2:
This is assumedly some time later and nick is sat in what appears to be some sort of hotel room.
NIck "motherfuckers, im not doing no steroids, if they wanna come in and smoke some weed im up for that"
Nick "ive told them im in room number 729 come drug test me motherfuckers im ready"
So yes. looks like Nick refused the test.
