Title says it all, on my order of 2g of K, I opened it and saw two baggies, one labeled 0.5g A-PVP and another labeled 3.5g EP. I tottaly understand orders can get mixed up, esp during the holidays, and I fully expect this vendor to honor his good name. Im lucky as my coins are still in escrow (no more FE!!). Im just confused because he doesnt list A-PVP in his store, and I have no idea what EP is. Time to get a test kit
Edit: Apologies to CanadianForger! Not his mixup, although I didnt have any other orders on the way when this happened, causing me to jump to conclusions.
As Sand said, the EP is most likely ethylphenidate. It was probably just a mix up in orders, the most likely outcome is that the vendor will send you what you ordered and just tell you to keep the order you got.
