I am in my third week of sustanon. i'm running 500 mg of sustanon a week for 10 weeks. Before i started i wanted to use deca too but it was way too expensive but i finally can get some cheap ass deca. I was thinking to add the deca next week and run it 6 weeks meaning i would end it one week before the sustanon. I'm also running test prop 50 mg when i stop the sustanon 18 days before pct.
