Vets/Athletes help me with a cycle

I am looking to get into a good cycle this summer. my goal is to lose weight and pack on mass. I am more interested in packing on the mass...right now I am taking cytomel and xenadrine so I am pretty sure that in a few weeks I will be at a good weight. I am also a track and field thrower and I am looking to add a lot of good explosive strength to my throws...I have been told that Test and winstrol will help me a lot with explosive power. But I am also trying to decide whether to use Deca or Equipoise for a base anabolic. I probably won't be drug tested for another 2 years so I am wondering which will be better for me in my situation. Please help me out

Thanks
