I got some ejuice called Stachio, very cheap on sale. Its pistachio ice cream. The only problem is its soo dark. In my tank its super dark brown and slightly red. Does this mean its gone bad? Im wondering if it was soo cheap because its super old. It tastes ok, but never vaped juice thats so black. I understand the millard effect but just wondering if juice has an expiration date, none listed on bottle.
