Npp/deca in my opinion is much better for bulking. If running high tren I pretty much cannot eat enough to gain (have a small appetite though all the time). High test/high deca-npp is pretty much the golden bulking cycle. If you are going to run two 19-nors together I would definitely know how your body responds and make sure you are keeping estrogen/prolactin very much in check. The potential for sides with deca and tren together is fairly high-especially potential for sexual sides cause by prolactin. But either way-on a true bulk I agree with knight9-high test with either compound you run will help gain mass. $$$ per ml, in my opinion, test is the best/cheapest bulking compound. I love test at 1g+. If you run tren I would do like test at 600-1g and tren e at 400-600 or you'll have to eat a lot-especially carbs-to gain substantial mass.
