Question Pseudoephedrine testing

[Capitan Salam]

I found pseudoephedrine from a local pharmaceutical company at a very good price, they sell it in 100g packages and there is an option to test for pseudoephedrine before paying for the shipment. How do I test to make sure that what they are selling me is actually pseudoephedrine. I have never seen pseudoephedrine and I have no knowledge of chemistry. Is there a simple reaction I can make?
