I recently started my second cycle of IGF. My first cycle I had stored the vial of IGF in the freeezer, and never had a problem with it freezing. Today I got the vial of igf that just purchased through MR, and had stored it in the freezer just as I did before, and when I took it out it was froze. It only took about 5 min to thaw, but my concern is that could it of harmed it at all? I appreciate any feedback.
