I think it's a good stack. Since TRN has been known to cause gyno easily in some, I think the epistane would work good to combat the estrogen related sides that it causes. Aslo you will have some crazy strength gains with this one, Tenadrol by itself increased my bench nearly 60 pounds and epistane has been known to have some great strength increases so get ready for the bar to bend. If your looking more for mass though you should look into max lmg clones, also none methylated and great for mass.
