- Freezer (−20°C)
- Lyophilised powder
- −20°C
- 24+ months
- <2% per year
- Optimal long-term storage. Standard protocol for research-grade peptides
- Refrigerator (2–8°C)
- Reconstituted solution
- 2–8°C
- 28–30 days
- 2–4% per week
- Maximum practical shelf life after reconstitution with bacteriostatic water
- Room temperature
- 20–25°C
- 48–72 hours
- 10–15% per 24 hours
- Unacceptable except during short transport. Return to refrigeration immediately
- Not recommended
- Ice crystal damage
- Never freeze reconstituted peptides. Protein structure irreversibly disrupted
- 3–6 months
- 10–15% per month
- Avoid entirely. Degradation accelerates without cold storage
