Questions are meant to be answered don't feel the need to stop asking them.
It should be more TEST than EQ, some say goodbye to their dicks when they go over, and some say its fine, but i wouldn't take a toll you don't know what/how your body will react.
Orals, run dbol for the first 3-5 weeks @ 20mg+(20 being minimum), and i wouldn't go over 50mg, as its just pure bloat at that point.
Pin monday/thurs is the most common, as doing every 4 days can be confusing, and yes if they are both oil based then you can mix them.
You should also stop your EQ 1 week before your test, so heres your final layout
Cyp= 600mg EW for 13 weeks
EQ=500mg EW for 12 weeks
Dbol=20-50mg ED for 4 weeks
PCT 2 weeks after last injection, since they are both long esters, once your done with dbol your test and EQ should kick in.
