^^^ Agree with jstone. I see no reason to dose the l-dex @ that concentration. Not really sure how well it would suspend at that concentration. It will be a tad aggravating to pull 1/20 of a ml to get .25mg of anastrozole. Personally, I would ditch it and buy new from some research company or preferably pharma.
Not to insult your source, but I have a feeling the reason the label is gone is that your source is hoping to keep himself in the loop as far as $$?
