You can train two times a day....on or off gear.
train the morning hard, rest and recover(eat eat eat) for like six hours, then go back.....ditch the compound movements and isolate. or lower the percentage quite a lot
or
do say quad work in the morning...then hamstring work at night. or pec and tricep morning, and back and biceps in the evening
just as long as you let your body recover the next few days
