  • Lyophilised powder (sealed)
  • −20°C with desiccant
  • 24 months
  • Moisture ingress, light exposure
  • Most stable form. Prioritise this for long-term storage
  • Lyophilised powder (opened)
  • 3–6 months
  • Repeated moisture exposure during handling
  • Single-use aliquots eliminate this risk entirely
  • Reconstituted solution
  • 2–8°C refrigerated
  • 28 days
  • Hydrolysis, peptide aggregation, microbial growth
  • Prepare only volumes needed for near-term use
  • Reconstituted solution (frozen)
  • −20°C
  • Not recommended
  • Ice crystal disruption, aggregation
  • Freezing reconstituted peptide destroys structural integrity
  • Room temperature (any form)
  • 20–25°C
  • 24–72 hours
  • Rapid thermal denaturation, oxidation
  • Irreversible potency loss. Never store peptides at ambient temperature
  • Peptide stability in aqueous solution is exponentially temperature-dependent. The table above reflects empirical observations from accelerated stability studies. Your actual results will vary based on vial handling frequency, buffer composition, and local humidity conditions. When in doubt, store cagrilintide long term as lyophilised powder and reconstitute fresh aliquots every four weeks.
