Strange differences in testex vials, please help I think they are fakes

[AnabolicAgent]

Ok, I am looking at some testex vials I bought a while back. The strange thing is that there seems to be 1/16 inch difference in height. One vial measures 2 5/16 and the other measures 2 4/16 but It makes the vials very different looking. The bigger one is bigger in diameter and the glass looks thinner and the lettering on the vial is a dull color which does not give off a glare when light hits it but the smaller ones do. Please help. I hope these are not fakes but I have been doing a gram a week for 7 weeks and I have not felt the test flowing like I usually do with say 500mg per week of some cheap mexican vet test.

Look underneath the bottles. Are the markings the same?

There are no markings on the bottoms of the amps. These are 250mg 2ml amps. What makes me suspicious is the fact that all of the larger amps all seem to differ in height (meaning that none of them are the same exact height), but the smaller amps that I think are the real ones are all the same exact height, which is exactly what I would expect from a factory.
