- Lyophilized powder
- −20°C (freezer)
- 12–24 months
- Original sealed vial
- Store in dark or amber vial
- Vacuum-sealed; moisture is the primary risk
- Reconstituted solution
- 2–8°C (refrigerator)
- 28 days maximum
- Sterile sealed vial
- Protect from direct light
- Bacteriostatic water preservative limits beyond 28 days
- Short-term transport (reconstituted)
- 2–8°C (insulated cooler)
- 24–36 hours
- Insulated gel-pack bag
- Minimize light during transport
- Use insulin travel coolers; avoid freezing
- Freeze storage (reconstituted, single-use aliquots)
- −80°C (ultra-low freezer)
- 3–6 months
- Sterile cryovials
- Not applicable
- Requires specialized equipment; freeze-thaw cycles degrade peptide
- Ambient exposure (reconstituted)
- 20–25°C (room temp)
- <48 hours before significant loss
- Not recommended
- Accelerates degradation
- Potency drops 15–20% within 48 hours
