- Lyophilised at −20°C (unreconstituted)
- 98–99%
- Minimal. Dormant state, no hydrolysis
- Gold standard for long-term storage; reconstitute only what you'll use in 30 days
- Reconstituted, refrigerated 2–8°C
- 92–96%
- Slow peptide bond hydrolysis, minimal oxidation
- Standard protocol; acceptable for multi-dose use within 30 days
- Reconstituted, room temp 20–25°C
- 60–70%
- Accelerated hydrolysis, moderate oxidation
- Avoid. Use within 7 days maximum if refrigeration unavailable
- Reconstituted, frozen −20°C
- 85–90%
- Ice crystal formation damages tertiary structure
- Not recommended. Freezing reconstituted peptides denatures them
- Reconstituted, refrigerated >30 days
- 80–85% at 45 days
- Cumulative hydrolysis, progressive oxidation
- Discard after 30 days. Precision dosing no longer reliable beyond this window
