I have 2 mass favourites............ no dosages quoted for noob safety reasons.

1 - Test - ALL esters - 20wk run with drol cycled 2 on 2 off thoughout with TNE pre/wout.

2 - Test - Tren E - EQ - 20wk cycle again with drol 2/2 + TNE - sourceing the best anadrol is a real bonus with these stacks.

Depending on specific goal either clean or dirty diet can/will bring results for me within the 5000/6000 cal range...... cycle 1 will be a wetter gain whilst cycle 2 will produce tons of vascularity with a cleaner type diet (not cal or carb restricted by any means) just lighter on the fats and sugars thats all.

androl 50 and deca work well for mass .

would not really call that a mass building stack

for full out mass
test e deca dbol
or
sust or test e and tren e with testt higher

I'm still tinkering with tren.. I've only done one tren cycle so far.. Coming up I'm cutting down then running a test/eq cycle with a tren kicker and dropping it in the middle of the cycle then using tren and mast as a finisher.. My best mass came from deca/test cycle but I ate like a fat ass.. I had issues with hunger on tren.. still made great solid gains from it.

My favorite mast building stack is 50mg test p, 100mg tren a, 75mg mast p ed. This is actually my cutting stack as well. The only thing I do that differs between the two is lower carbs, a few less calories, and more cardio while cutting. While bulking, I'll consume roughly twice as many carbs and around 5k in calories. Cardio is kept to about twice a week just to help maintain endurance levels. I may also add anadrol or dbol during a bulk and tbol or var during cutting. But essentially my stacks are the same. Diet is absolutely key for me. With trens incredible ability to improve feed efficiency, all I really need to do is add or reduce calories to get what I want.
