i actually ended up doing the following
SDNG: 3caps pre-w/o only
MassFX: 6caps a day
HDx2: 3caps a day
I will run an extra mfx bottle till the SDNG runs out, then do a small pct anyway of aPCT and PrimalMale.
I kinda like this mfx better, the older version did feel a little stronger in the perception department but didn't translate very well to workout performance. the new mfx/sdng stack felt really awesome in the gym, and the mfx alone feels nice but not over the top. i am still in week 1 of this but i like it...
