What to stack with Primo? EQ ,Parabolan or Masteron?

[saguakid]

I will be adding Primo toward the end of my tren ace, test prop,anavar cycle that im running for 10 weeks,I want to extend it and add Primo Schering 300 mg/ week on week 8 for 10 weeks,by that time my body fat should be 9% or under.
My options to stack Primo are Parabolan,EQ or Materon
Parabolan is like tren and im already using Tren Ace,dont know if will be safe,with EQ I could keep vasc at 600 mg/week,other choice will be Masteron,any feedback i will appreciate it
