Raising amount first couple levels on button with KK/AA limpers?

[Vetstadium]

Say you are on the button with AA/KK first 2-3 levels of a buy in $50 or less. Say if there are 3-4 limpers how much do you raise normally? I know you want some action but everyone loves to call raises early. I want to isolate but not cause chain reaction of 4 callers. I normally bet 2x the pot in this situation.

I think the standard raise is around 3x the bb and 1 bb per limper.
