winst. or deca

For my cycle I will run 500 mg test-e (Nolv., etc,)
But I want to stack it with one other thing.

I was ready to order Methanabol 10 mg tabs with it for mass, but because of my gyno problem and now my 6 pack is just out of visability, I'm thinking of stacking with winstrol tabs or Deca instead.

I would like to see the six pack again and want the gyno to shrink or go away bad. Would winstrol or deca be a better choice to- be easy on the gyno,see the 6-pack again and give the most muscle?
