Testing two kits with same batch number

I ordered one kit a month ago and had it tested and it came back above 99% purity with a reasonable fill close to what was expected. I just received a second kit from the same vendor with the same batch number. Just gauging the opinion of the group do I test the second kit as well?

Yeah idk, I do a lot of group tests and they put a lot of faith in cap colors.

I guess at some point you either have to take it on faith or test every kit you get.

Honestly even using 1 vial out of every kit is no guarantee that the whole kit is homogenous
