Sten/Tren would be a great combo. A little drier than DMZ/Tren imo. You can't go wrong either way. Both are great compounds and yield very similar results. I found Sten to be just a tad drier. Mass and strength gains are a wash. I don't recommend stacking the two methyls unless you plan to do pre/post/post pct bloods. It really is an eye opener to see what just one methyl can do to your liver, blood pressure, and cholesterol levels, let alone two strong methyls + Tren. The added mass and strength from stacking would not be worth the increased risks IMO.
