Question for the US: how are you all so calm about long-term freezing?

A 47-post discussion is drawing sustained community attention to a transatlantic divergence in cold-storage practice, with several contributors citing evidence that lyophilised peptides stored at cool, dark temperatures may retain potency over extended periods without strict freezing protocols.

Even if they warm up for a week they probably aren't trashed, likely just some minor degradation. Yeah, freeze thaw cycles should be avoided, but I imagine un-reconstituted peptides would still be effective after years in a cool dark place.

Agreed. There are a number of accounts that lyophilized vials having sat merely cool and dark, lasted years with nominal degradation. The whole freezing bit is perhaps the majority peace of mind, but may not even be necessary if temps and humidity are stable.
