you know, 300 mg a week isnt much of a cruise. it will affect your blood levels negatively, so your pretty much just using.

i would rather not lose any muscle at all so how much should i up my test in order to minimize muscle loss as much as possible

you definitely don't need to increase your dosage on DNP. The latter has anti proteolytic properties (protein sparing-), so, assuming an adequate protein intake, even non geared cutting should give you minimal LBM loss. just be aware that increased aMPk (Pelletier et al. 2005) resulting from DNP will increase your carb cravings significantly. Maybe add some EC to blunt that. You'll look flat as hell while on cycle b/c glycogen will be depleted, don't confuse that for muscle loss.

better response you will have to hormones.

yes, better insulin sensitivity and partitioning, although I suspect the latter might not really matter if you're doing a geared bulk in the first place.

High protein and getting all your carbs from veggies should get u there also
