Tren is a pretty unique compound. I save it for cutting usually. With your next blast, I'm assuming you want to focus on some good lean gains? If so, a great addition would be NPP. I find that for most people, the side effects are very low compared to Deca. It works great for staying full and anabolic while dieting without a lot of added bloat, or it works great in a bulking plan, to get anabolic quickly while you wait for the long esters to work. Between your Sust and NPP, you'd start to feel a change within a short time (2 wks). Then you could drop the NPP later, when the EQ has built up (say 8 wks in)
