Just delay it a few weeks.
That being said the livertoxicity is so overrated. I don't recommend drinking on orals but have done so many times, as literally everyone I know that runs gear has (and these aren't just idiot gym rats, american jr bench record holder and a few NPC national level competitors).
It's not instant death as many claim it to be. In fact i've gotten bloodwork on anadrol after getting wasted and my liver values were ast/alt 25-30, aka perfect.
now that's not saying you would be fine to do so, everyone gets different sides and can tolerate things different.
AGAIN BEFORE PEOPLE FREAK OUT I'M NOT SAYING THIS IS "GOOD" OR THAT OTHERS WILL HAVE NO ADVERSE CONSEQUENCES
