Has anyone taken NOx? Is it any good? I am currently bulking and I work a graveyard shift while my fiance is a daywalker...So flip flopping between a night life and a day life often leaves me feeling sluggish while I lift...I heard this stuff is good for energy but I don't want to add any (or at least not too many) calories in my diet as I need the cals from the food I eat and only want a SMALL surplus in my diet (since I worked my butt off getting down to 9% bf)...Advice??
