You would definitely benefit from some slow steady state cardio. You can actually get away with doing it every day, since it is low intensity. I usually do 20-30 minutes a day, 20 minutes on days I train and 30 minutes on non-training days. I prefer fasted, but if that is not feasible at least get it in.
As far as tren, I am all for it. However, no matter what dose or ester I am running I still limit the duration to 8 weeks. I have done as little as 25 mg of tren ace 3x per week and as much as 75 mg eod with similar results when it comes to cutting. However, nothing, and I mean nothing, compares to parabolin at 100 mg every 3 days. I have never felt anything like it.
You could also throw in some clen and T-3, but clen and tren together might dry you out. I ran tren, clen and winstrol last year. After week four, no bueno.
