Are you asking if sust and Deca will work together or what?
Sust and Deca will work fine, but the most important thing is going to be your diet and training regimine not your juice.
First time cycler could do well with sust alone, adding deca is safe, stacking both of those with Dbol for a first cycle is a bit much IMO. Not that it isnt safe, but the triple stack may be a bit strong for the first cycle. Mixing 3 drugs will make it impossible to tell which drug is causing sides if you experience sides.
Test and EQ or Sust and Deca are fine - either one will require your diet and training regimine to be dialed in to see best results.
