- Lyophilised (freezer)
- −20°C
- 18–24 months
- 98%+ retention
- Gold standard for long-term storage. Minimal degradation if light-protected
- Lyophilised (refrigerator)
- 2–8°C
- 6–8 weeks
- 85–90% retention
- Acceptable for short-term but oxidation accelerates. Use freezer when possible
- Reconstituted (refrigerator)
- 28 days
- 95% retention
- Only viable post-mixing option. Strict 4-week limit due to preservative lifespan
- Reconstituted (room temp)
- 20–25°C
- 6–12 hours
- 70–80% retention
- Emergency tolerance only. Degradation begins within 2 hours of room exposure
- Reconstituted (frozen)
- Not recommended
- <50% retention
- Ice crystals physically shear peptide structure. Avoid entirely
