One of the most common questions in the peptide community: can you store peptides without a fridge? The short answer is — it depends on whether they're lyophilized or reconstituted.
Lyophilized (Dry) Peptides — No Fridge Needed Short Term
Lyophilized peptides are freeze-dried powder sealed in vials. In this form, most peptides (BPC-157, TB-500, CJC-1295, retatrutide, semaglutide) are stable at room temperature below 25°C for weeks to months when stored away from light and moisture. For travel up to 2 weeks, a dark, cool location is sufficient.
Reconstituted Peptides — Refrigeration Required
Once you add bacteriostatic water, the clock starts. Most reconstituted peptides should be refrigerated at 2-8°C and used within 28-30 days.
What Always Helps: Physical Protection
Whether refrigerated or not, glass vials need physical protection. A VialLock hard-shell case protects vials from breakage, pressure, and light. Shop VialLock travel cases.
