no need to nit pick over dose and be splitting caps and all that shit. I would never do that, caps can be iffy to begin with b/c the drug doesnt distribute evenly amongst the filler (varries by source of course)
25 dbol / 50 drol is fine dude, dont worry about splitting over the day, or trying to do 35/75 or anything else. for just 4 weeks your liver will be fine, its not an unreasonable dose at all. Take both upon waking IMO. I like the combo over more of each as well, but that's individual
from a health perspective i honestly think the arimidex is a bigger risk than the dbol/drol, liver recovers faster / easier than cholesterol issues. 1) do you KNOW you need an AI? you might be fine w/o one. 2) if you do need one, go with aromasin
