Storing CJC-1295: Best Practices
Lyophilized Peptide Storage
Store lyophilized CJC-1295 vials at -20°C (-4°F). Lyophilized peptide is stable for up to 24 months under these conditions. Protect from light and moisture.
Reconstitution
Reconstitute with sterile bacteriostatic water (0.9% benzyl alcohol) for extended stability. Use a slow, gentle swirling motion — do not shake vigorously. Allow to dissolve fully before drawing.
Reconstituted Handling
Once reconstituted, store at 2°C to 8°C (36°F to 46°F). Use within 14–21 days. Avoid repeated freeze-thaw cycles, which degrade peptide integrity. Discard if solution appears cloudy or contains particulates.
