This dude came out clean?
Test suspension only has a 24hr half-life and orals are quite short HLs also. You can read reports that USADA don't actually perform CIR testing, they can but choose not to for some reason (they're $500 each) which would only work in a 24hr window anyways and not between 11pm-6am. CIR would be the only way to catch a syntheic test* user.
*Syntheic testosterone is made fromm yams which looks slightly different from natural testosterone which is how a CIR test would catch it. You can instead make testosterone from animal cholestrol which will NOT show up in a CIR, unless they found some other wya to view the markers, because it has the exact markers as natural test.
I think countries with state sponsored doping have real exotic designer steroids that are way ahead of WADA tesing, look at BALCO they would never have caught them unless a coach snitched.
