Query: Yuck

Besides having a great deal of problems with the seller, this protein smelled rancid when I opened it and had no vanilla taste.I did not want to test it any further for fear of food poisoning, but the quality control just isn't up to snuff. Maybe this is a 1 in a 100 event, but I'm sure I don't like those odds when it comes to my food and health.
