What happens if test cypinate gets frozen? I am working out of town and my luggage will be out in the cold for the drive there. Will it still be good after thawing out? I know that is is supposed to be stored at room temp. But now that I think about it it was shipped to me in the cold. This is my first go with test so I'm new to everything. Will this ruin my test? How important is it to keep it from freezing?
