Ah, yeah I understood the 500mg pw straight off the bat so all good there.
Arimidex needs to be dosed EOD, it just works better that way.
.5mg every third day won't cut it at those dosages if the gear is real, and doing it every day seems to make adex not so effective (I know 'more stable' blood levels seem completely logical, but it doesn't work that way in practice) even if the weekly dose is the same. Most guys find it has to be 'pulsed' every other day for maximum benefit.
I can only speak for myself here, but if I was going to do dbol and 500mg of test I would be taking at least 1mg adex EOD and then reevaluating from there.
