If I was to stack these two together, I would run the Halo first, as it takes longer for this to kick in- at least a week- and run it for 6 weeks- first week at 75mg and 100mg for the rest of the time. Add DMZ in for the last 4 weeks of the cycle.
I would also take with some oil or peanut butter to help get it into your system
Be sure to eat like a wild horse, and get lots of sleep.
That's just me though
