Do peptides need to be shipped cold with ice packs?

Freeze-dried peptides generally do not need ice for a short trip. Data show freeze-dried peptides stay stable through normal shipping of a few days, at room temperatures below about 30 degrees Celsius. That is why many sellers ship them without ice. Cold storage matters mostly for keeping them a long time, not for a short trip.
