- Lyophilised powder (unreconstituted)
- −20°C (standard freezer)
- 12–24 months
- Moisture ingress and oxidative degradation. Potency loss 5–10% per month at room temp
- Non-negotiable. This is the only storage state with multi-month stability
- During reconstitution
- Room temp (20–25°C) briefly
- 2–5 minutes maximum
- Thermal stress begins immediately but damage is minimal if brief. Do not leave mixed vial out
- Reconstituted solution
- 2–8°C (refrigerator)
- 28 days maximum
- Hydrolysis and oxidation. Potency drops 10–15% in first month, accelerates beyond that
- Standard medical refrigerator is ideal. Avoid door storage due to temperature swings
- Short-term transport
- 2–8°C maintained with cooling pack
- 24–48 hours max
- Any excursion above 10°C risks partial denaturation. Peptide may appear normal but lose 20–40% activity
- Use purpose-built peptide travel coolers, not ice packs which can freeze the solution
- Frozen reconstituted (emergency only)
- −20°C
- Not recommended
- Ice crystal formation physically shears peptide chains. Expect 30–50% potency loss on thaw
- Freeze only if disposal is the alternative. Never freeze as routine storage
