Peptides degrade through hydrolysis, oxidation, and aggregation. Each of those processes accelerates with heat and moisture, which is why storage is not a footnote.
Lyophilized powder tolerates ambient shipping temperatures far better than solution. That is precisely why compounds ship as powder.
At rest, a dedicated refrigerator shelf away from the door is the simplest meaningful upgrade most people can make. Temperature stability matters more than the exact number.
For long horizons, a freezer at minus twenty preserves lyophilized material well. Avoid repeated freeze-thaw cycles; decant into aliquots instead.
