nolva would probably need to be run higher than 10mg, long term studies for gyno reduction involved 20mg doses for 3-9 months if i remember correctly.
letro is usually the fastest working for gyno reduction, most favorable reports i've seen have combined letro and nolva or letro and raloxifene. with dosing as follows
nolva 20 or 40mg, letro 2.5mg until subsides (usually 2-4 weeks) then continue to run nolva for 2 weeks after letro to control estro rebound.
i personally used letro tapering up to 2.5 and back down for 2 weeks got about 50% reduction with partial rebound back to maybe 30% reduction. and honestly it probably did just as good at .5-1.25 mg as it did at 2.5 with much fewer sides
i intend to get some nolva and run 20mg/day alongside 1.25mg letro
masteron would probably help and dostinex could as well, but block out the estrogen and the tissue will at least partially subside
