I've never purchased from them, but I have a bottle of the TFA Cheesecake Graham Crust from Bull City. It is re-bottled, (translucent) pale yellow. I know the flavoring is fine, since I've purchased direct from TFA in the past. Hope that helps you a bit in determining your bottle.
Thanks for the heads up with your order! As you said, get it direct from manufacturer, or a trusted site in the future. I'll vouch for BCV or Wizard Labs on a good product for that flavoring.
