Use preferably Aromasin on cycle to control estrogen, i have never used it so cannot comment on dosages for this,
i also used 1 mg of Arimadex a day when i was using it to combat the sides from 100-150 mg of the oral version Tr3st but i was also running 250-500mg of Test E per week and 300mg Tren E.
for PCT Clomid is a better suited option in my opinion and others will agree that it works better than nolva, i used the 2 but most say just clomid at a dose of 50,50,25,25 should be enough or a longer run could be 50,50,25,25,12.5,12.5,
Nolvadex lowers IGF which is the major off-putting effect which is not the greatest thing on cycle or during PCT.
