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.
Equipoise is highly effective not only for mass but also for contest preparation (cutting) since it aromatizes very poorly. Muscle hardness and density can be greatly improved when Boldenone is combined with steroids like Proviron (mesterolone) , Parabolan (trenbolone hex), Halotestin (fluoxymesterone) , or Winstrol (stanozolol). For cutting it also stacks with nandolone phenilpropionate, possible cycle is 300-500 mg of boldenone plus 300-500 mg of nandrolone-ph for 6-8 weeks. It could be used in a final (relief) part of a longer cycle at 100-200 mg/week along with winstrol (stanozolol) 50 mg/day for around 6 weeks.
