❄️ Core Rule: Lyophilized powder — refrigerate (2–8°C) or freeze long-term. Reconstituted solution — refrigerate only, NEVER freeze. Both — protect from light.
Lyophilized Powder Storage
- Short-term (≤6 months): Refrigerate at 2–8°C
- Long-term (6+ months): Freeze at -20°C
- Light: Keep in original vial away from direct light
Reconstituted Solution Storage
- Location: Refrigerate at 2–8°C — do NOT freeze
- Duration: 30–60 days depending on peptide
- Light: Medicine cabinet drawer ideal
Never freeze reconstituted solutions — ice crystal formation physically damages peptide structure. Bacteriostatic water's benzyl alcohol inhibits bacterial growth for 30–60 days refrigerated.
