Are you especially sensitive to Estrogen? I would think 400mg of mast would protect you from any sides without needing an a.i. 400mg of test a week shouldn’t aromatise much (unless you’re really sensitive or extremely fat).
IMHO, most people cut their E way too low without rhyme or reason. Low Estrogen = low gains.
I’d ditch the a.i. entirely but have it on hand in case you develop symptoms (but that’s just me - I’m currently bulking on 1g week test-e, 60mg a day of d-bol (as far as “wet” compounds go) and no anti-estrogens other than 700mg of mast a week). Also 700 tren-a and 600mg deca, but they don’t aromatize. Been on 6 weeks and no gyno yet.
I’d go with the higher number on DHB. 200mg probably won’t do much (YMMV, of course).
OOOPS! I didn’t notice how old thos post was before I responded. LOL!
