if you go to the avant labs site that is where you buy it from, and you can read information on it there + it has links to threads on other bb forums about the product.
I recently ordered some myself. I dont know if it works well and its a lot of money to gamble, but the posts on it seem positive, lots of people say its 'good stuff'. Have to wait and see.
If you search for '1-test' or 'par deus' you might find more information.
