- Standard refrigeration (2–8°C)
- 24–36 months
- 28 days maximum
- 2–8°C maintained continuously
- <2% monthly potency loss
- Optimal for both forms—this is the gold standard for peptide storage
- Room temperature (20–25°C), <48 hours
- 90–95% potency retained
- 40–60% potency loss
- 20–25°C brief excursion
- 5–10% loss (lyophilised), 30–50% loss (reconstituted)
- Salvageable for lyophilised only—reconstituted peptides require disposal
- Room temperature (20–25°C), >72 hours
- 80–90% potency retained
- <10% potency retained, functionally inactive
- 20–25°C extended excursion
- 10–20% loss (lyophilised), >90% loss (reconstituted)
- High degradation risk even for lyophilised—reconstituted solutions completely compromised
- Elevated temperature (30–35°C), any duration
- 50–70% potency loss within 48 hours
- Complete degradation within 24 hours
- Above 30°C
- Exponential—irreversible oxidation and aggregation
- Discard regardless of form—thermal damage cannot be reversed
- Freezer storage (−20°C)
- Indefinite if no freeze-thaw cycles
- Irreversible aggregation and precipitation
- −20°C or below
- Minimal for lyophilised; catastrophic for reconstituted
- Safe only for unreconstituted peptides stored long-term
- Shipping without cold chain
- 60–80% potency loss in 24–48 hours
- Near-complete loss within 12 hours
- Uncontrolled ambient (15–30°C)
- 20–40% daily loss
- Always require validated cold chain—ambient shipping destroys peptide integrity
