- Lyophilised (unopened)
- −20°C ±2°C
- Borosilicate glass vial with PTFE cap
- 24–36 months
- Gold standard. Maximum stability, minimal degradation risk
- Lyophilised (opened once)
- Same vial, resealed with desiccant
- 18–24 months
- Acceptable if resealed immediately; moisture exposure during opening reduces shelf life by 20–30%
- Reconstituted (in use)
- 2–8°C
- Amber glass vial, bacteriostatic water
- 28 days
- Industry standard; >95% purity retained through day 21, >90% through day 28
- Reconstituted (backup aliquot)
- −20°C
- Cryovial, sterile seal
- 3–6 months
- Suitable for long-term backup storage; freeze-thaw reduces activity by ~10% per cycle
- Room temperature (short-term transport)
- 15–25°C
- Insulated peptide cooler with ice pack
- 24–48 hours maximum
- Emergency transport only. Prolonged exposure above 8°C causes irreversible degradation
