That's a knock-off for sure, although I have to give credit for using the vials with the smaller mm top and all.
I've got a bunch of the Sandoz stuff from the pharmacy. I've never used any of it. Pharmacy recently started giving me the Watson stuff again which I prefer. Larger vial top and I can reuse the vials because of that. Although I'm sure the contents off each are nearly identical.
Regarding the knock-off stuff, just because they are imitating doesn't mean that the vial doesn't contain real gear. Still, the fact that it is a knock-off means that you have no idea where it came from and the lab likely doesn't have a name for themselves since they don't even have a UG lab name to apply.
