Hi Folks, A bottle of prozinc arrived this morning (now available in the UK) from Weldricks. It was packed in a large box with an ice pack that felt warm. The insulin was not as cold as it should have been. It was 10.4 degrees Celsius. I have had experience of insulin arriving and it already having gone off. What do you guys think - will it be ok? Am I being paranoid. It came on an overnight delivery and was in the postal system from about 18:00 hours yesterday until 12:15 pm today - 18 hours or thereabouts. Thanks
