OK...for starters, what is a d-bol/winny tab? I know your not saying its the same tab? One is a muscle hardener commonly used in cutting phases while the other is a bulking AS. I know your not talking about taking winny and d-bol together like that, with both being 17aa your liver will go through Hell.
And although EQ and Deca hit the same receptors, unless you absolutely have to I wouldnt just run Deca 6 weeks and switch 3 weeks before my cycle ends.
