If I had to choose between Halo and Winny I would go with Halo, but since winny and tren have a synergistic effect with each other would it be better off to do winny? BTW the cycle will be Test Prop 100mg EOD, Tren 100mg EOD, and either winny or halo. And I also really am anxious to try halo, but I'm not sure if I should replace it in this cycle.
