SS-LUP-332 Lyophilized Powder: Handling Comparison Across Storage Phases
Unreconstituted (sealed vial) −20°C ± 5°C 24 months Minimal (sealed under inert gas) Peptide structure fully stable; moisture and light exposure are primary degradation factors Reconstituted (bacteriostatic water) 2–8°C (refrigeration) 28 days maximum Moderate

- Unreconstituted (sealed vial)
- −20°C ± 5°C
- 24 months
- Minimal (sealed under inert gas)
- Peptide structure fully stable; moisture and light exposure are primary degradation factors
- Reconstituted (bacteriostatic water)
- 2–8°C (refrigeration)
- 28 days maximum
- Moderate (repeated needle punctures)
- Antimicrobial agents prevent bacterial growth but not peptide degradation; no freeze-thaw cycles
- Short-term transport (ice pack)
- 2–8°C maintained
- 24–48 hours
- Low if sealed properly
- Use insulated containers with gel packs; avoid direct ice contact (freezing risk)
- Room temperature exposure (emergency)
- 20–25°C
- <2 hours total cumulative
- Increased if vial opened
- Degradation accelerates rapidly above 8°C; return to refrigeration immediately
