You can test it yourself with EZ test kits, you can test for purity with one type of test and active cuts with another. As Aussie bob rightly pointed out you cannot get direct support from the forums, you will need to take this to resolution on the main site so it is very fortunate you are in escrow. Hit the resolve option next to the order and state your claim in that you consider you have been sold something that is not as described. If this has happened to you then you can bet others are in the same boat so you may also want to ask on the forums re others also experiencing issues. As always though the first port of call should be the vendor, contact them and explain what you consider has happened and see what they have to say, you may have been sent a badly mixed portion of the brick, happens with coke sometimes and you end up with more cutting agent that actual coke. Hope that helps.
