Test E/Dbol with Letro Gyno Reversal

I am planning to start a test e/dbol cycle but had a few questions about letro gyno reversal before I commit.

I plan on running:

wk 1-10 600mgs test e
wk 1-4 30mgs dbol
wk 13-16 nolva 40/40/20/20

Pretty basic however, I have a very minor case of gyno from a while back, it’s not bad just a small hard lump. My question is should I start a letro gyno reversal program whilst on my cycle, doing 2.5mg ED or use .25 ED just to keep it from getting worse and then do the reversal during or after PCT

Also would 2.5mg of letro ED spoil my gains?
