The best non-stim suppliment to help with staying lean is a nutrient partitioner, although in looking at your new stack, it seems like some of the ingredients function in that regard.
You will be fine, your body needs this more than you need to avoid fat, fat can be removed, just don't go overboard on anything. You are incredibly lean in your avatar. Let your body relax, your mind needs the break from the stims as well. Heck, maybe give some natty test boosters and such a try as well for a mini-leangains cycle of sorts (DAA/Erase combo?). With how long you've been "dieting" (as far as your body can tell) you should be more than primed to add some quality mass as long as you keep the calories clean and high enough.
