Does anyone know if below freezing temperatures negatively affect ampules of B12? My latest order from Canada was left in the mailbox overnight and it was a very cold night.

instructions are not to pl in a freezer. I believe this is because the water in the vials will vial expand and the vials will shatter.

They didn't shatter so maybe the B12 is still good.
