Mac,
I have a great source.. I did have to return the last of my aratest, and that is what he gave me credit for. He did not give me credit for what I had used..I do not think that is foolish..... And I never faulted him for the quality....
And as far as the quality is concerned,the post What Are Your Aratest Lot #'s tells me there is alot of underdosed Aratest out there........
