- Unreconstituted (lyophilised)
- −20°C (−4°F)
- 24–36 months
- Minimal. Solid-state stability
- This is the gold standard for long-term storage before mixing
- Unreconstituted (refrigerated)
- 2–8°C (36–46°F)
- Up to 90 days
- Minimal in absence of moisture
- Acceptable short-term if freezer unavailable, but −20°C preferred
- Reconstituted (correct refrigeration)
- 30 days maximum
- Slow hydrolysis and oxidation
- Refrigerate immediately after mixing and use within one month. No exceptions
- Reconstituted (temperature excursion)
- Above 8°C (46°F)
- Potency loss begins within hours
- Rapid denaturation, disulfide scrambling
- Irreversible. Cannot be salvaged by returning to correct temperature
- Frozen after reconstitution
- −20°C or below
- Not recommended
- Ice crystal formation disrupts peptide structure
- Freeze-thaw cycles cause aggregation and loss of bioactivity
