bro u need to do more research ,
never stack E Q with deka .. both raise your RBC’s (red blood cells). anyway I would go with E Q over deka, and E Q should be ran minimum 600mg/wk.
For the rest deka and E Q are both very high in anabolic nature but very mild in androgenic nature. Stacking deka with E Q is almost like stacking Test with Test.The only reason IMO that I can see using both is 1) deka to help lube your joints if your having problems..2) EQ to maybe help the appetite. You would be better off Using Test and Deca or Test and EQ.
