Man, I'm really sorry that you're having to go back to court, that blows. Hopefully you will just get the extended probation and no juvenile detention.

I don't know much about the juvenile justice system there, but I know here if you aren't violent, and haven't been in trouble for violence-related crimes you pretty much just get more probation time and fines. Good luck. I tried googling for creatine levels, but all I could find was stuff about blood tests and 24 hr. urine tests.
