Tren in either ester can have wicked sides, long ester I have always experienced the sides to a lesser degree, but still there. If your hell bent on Tren at this point, go the short ester route and run it for 6 weeks and see how you feel. My personally opinion, at 3 cycles deep you're better off to run masteron in this stack instead of Tren. Again, you can use a short or long ester version. I seen your pics, you already have a lean build. Masteron would serve you well and compliment the test greatly too, and I've always liked a mast/test/EQ stack as well. My advice, swap tren for masteron at this point.
