Aromasin will reduce your bloat on D-bol
You can take it EOD ,most dose at 12.5mg/day OR 25mg EOD but it is really dependant on the sides your experiencing, many run it at 25mg/day.
You can take Aromasin throughout your cycle and into PCT, many run it for a week or two prior to running their cycles. I would recommend running it ED of your cycle. PREVENTION IS BETTER THAN THE CURE.
