Bests & Worsts Reviews from Amazon

I purchased 8 tubes (2x 4 Packs) and I am noticing that there are some differences in packaging from what I typically get from the dentist. After trying the gel, it does not seem to have the same consistency or "bubbling on teeth" characteristic of the gel provided by the dentist. --- I do not believe that this is an authentic product. --- I have attached photos... The first photo is the expiration date + Batch number of the syringe in question - The expiration date on the paper that came with the tubes differs from what is actually on the tube. In all subsequent photos, the bottom syringe is what I received from my dentist and the top is what I received - You will also notice the difference of the gel in the actual tube itself.
