I was gonna use Test/Tren for my next cycle, but after reading about some bad (maybe uncommon) sides, I decided against it, and I'm just gonna stick with Test/Deca which I've done before.. The thing with Tren is, sometimes you hear about guys talking like it's the best roid out there.. But then you hear other guys that say they expected so much more from it and weren't impressed..
Maybe I'll try it some day, but for now the tried and true Test/Deca is what I'm sticking with. Since Deca is a long ester too, you may as well use a longer estered Test with it too, like E or Cyp. I think Prop would be better with NPP (short ester Deca).. But if you were gonna do Tren Ace, Prop would be a good match for that.
