So many options! haha.
I would run M Test and Inhibit E together, then Bulbine and Reduce XT together just to get a couple of runs out of the products. You could run all 4 together, but from a cost:benefit perspective, I'd split them up.
M Test:
1 serving at lunch then 1 at dinner
Inhibit E:
1 serving pre bed.
Reduce XT:
In the morning take 1-2 servings, You could also take one again at night (or a few hours post workout) if you don't take 2 in the AM. I normally split the dosage where I can 1-1 and just do morning and night.
