- Lyophilised powder at −20°C (unopened)
- 12–24 months
- Minimal—lyophilisation removes water, preventing hydrolysis and oxidation
- Gold standard for long-term peptide storage; always verify vacuum seal integrity
- Reconstituted with bacteriostatic water at 2–8°C
- 28 days maximum
- Oxidation of methionine residues, hydrolysis at peptide bonds, benzyl alcohol preservative depletion
- Standard use window; discard after 28 days regardless of appearance
- Reconstituted at room temperature (20–25°C)
- 6–12 hours
- Rapid bacterial growth, accelerated oxidation, loss of tertiary structure
- Emergency only—return to refrigeration within 2 hours to minimize loss
- Frozen post-reconstitution (below 0°C)
- Not viable
- Ice crystal formation ruptures peptide bonds; freeze-thaw denatures proteins irreversibly
- Never freeze reconstituted peptides; this is not reversible
- Exposed to heat above 30°C (any duration)
- Immediate loss
- Protein denaturation, irreversible aggregation, complete loss of bioactivity
- Discard immediately—heat-denatured peptides cannot be salvaged
