All I can say is 0.5mgs eod is not the equivalent and will not bring the equivalent results as 0.25mgs daily.
on this we do not argue - it is not the same to be sure but it may, for some, be sufficient. A good example is tren, which in theory could be taken EOD but has significantly better results taken ED, the half life is long enough but ED keeps blood levels more constant.

As to your other oft repeated question - i simply fail to seee how the chemical process of the half lfe of a drug would be any different between a 55 year old woman and a 25 year old man. Absorption, binding affinity - yes, half-life NO.

but no I havent had the time to dig up a study that probably doesnt exist yet - we both know how many docs are using arimdex for 25-35yr old men
