you need anabolics to mitigate the potential muscle loss.
50mcg was fine for me. i won't advocate using it with DNP unless your cycle is longer than a couple of weeks.
my sweet spot is to run DNP 10-14 days max, stop, take a break, and start again a month or so later.
if you want to run DNP for long periods of time though, t3 can curb whatever thyroid function impairment caused by the DNP, how much it actually is, i can't say because i've never had the bloodwork to prove it, but i've heard it many times elsewhere. it's an indirect mechanism of how dnp works, i can't remember the exact wording as i don't have the study on hand, but it does in fact happen eventually.
THAT BEING SAID ------ if you want to combine these two, make sure you have ANABOLICS. hell, i won't even run DNP without a hearty 500mg dose of test JUST IN CASE. add t3 in the mix and i'm using something like test/deca while cutting.
