Arimidex to Femara (letrozole) conversion amounts

Need to know how much fem is equal to taking .5 or 1mg ed of arimidex .

Well bro, Femara, is supposed to be better than Armidex. However, I haven't found any studies on this particular subject, doesn't mean they are out there. But judging from what I have heard and been told, I would think that femara, would be administered the same, .5eod. I usually take armidex (depending on what AS I am using), .5mg every 4 days or so. Armidex usually stays in my body for long periods of time, well stops the arimotozation for that long anyways. I can usually tell when it is time for me to take alittle armidex.
Sorry I can't be more help than this though, but I will bump it for ya, to see if any of the other "more experienced" guys can help with this one, cause I am sorta curious myself.

Thanks bro. Doesnt seem like many people know the answer. I have heard that Fem half life is much shorter than arimi so you have to take it ed in order to maintain steady levels. Not sure how accurate that is. I'm hoping that one of the vets or mods know that answer.

Half life of Femara is 2 days.

I thought that 2.5mg of femara is roughly the equivalent of 1mg of armidex...

McBain has the same info I have. 2.5mg femara = 1mg arimidex .
