I have a chance to get some 4ad, which I have been wanting badly, however, it is not from any of the companies I have used before. I was thinking of getting just a small quantity at first and having it tested. I was wandering if you guys know of a way to test it and make sure it is indeed 4ad, or is there an independent lab I could send it to for analysis? I know I sound a little paranoid, but it has been so long since the ph ban that I was shocked to find some for sale, and thus, I am afraid it may not be legit.
