They look legit from what I can see. If they are fake, the people making them have expensive packaging equipment (ink jet code and amps are not the cheap heat up at home and seal kind).
There are a couple of other tests you can do to help verify.
1. Line up all of the amps next to each other and make sure they are filled to the same level. A pharmaceutical company uses precise filling equipment and is regulated by strict procedures & guidelines(GMP's, etc).
2. Make sure they all sit upright and do not have any abnormalities. Back in the day it was very easy to spot fake amps, a lot of times they would lean to the side or look deformed. Again, a pharmaceutical company has precise equipment and any abnormalities should be a red flag.
Hope this helps.
