.25 mg arimidex tabs ?

Has anyone ever seen or taken legit .25mg arimidex tabs. This is what I have ordered, but I haven’t heard anyone speak of them. Just a little worried, this is one thing I really can’t afford to be fake.

I have never seen of or heard of anything less than 1mg tabs. I am glad it only costs me 20 bucks for 30pills. insurance is great
