Personally, I wouldn't. Tren and deca are both 19-Nor based compounds. Each one alone, can cause issues with proges or prolactin. I would prefer to use EQ, if I challenged to find a good anabolic to add to the stack. I would use EQ for the full 12 wks. If you have done several cycles and have the experience, I might even extend the cycle to 16 wks and use the Tren E for the last 12 wks, then Win for the last 4-6 wk. You may need more arom than 12.5 but you'll have to see how you react
