CJC-1295 Storage: Reconstituted vs Lyophilised Comparison
Lyophilised powder (unreconstituted) −20°C to −80°C 24–36 months Minimal. Powder form is photostable Yes. Freezing is the recommended storage method Store in original sealed vial; once opened, use within 90 days even if refrozen Reconstituted in bacteriostatic
This comparison does not assign a generated winner or score.
- Lyophilised powder (unreconstituted)
- −20°C to −80°C
- 24–36 months
- Minimal. Powder form is photostable
- Yes. Freezing is the recommended storage method
- Store in original sealed vial; once opened, use within 90 days even if refrozen
- Reconstituted in bacteriostatic water
- 2–8°C (strictly maintained)
- 28 days maximum
- High. UV and visible light accelerate oxidation
- No. Freezing destroys peptide structure
- Must be refrigerated immediately; temperature excursions above 8°C cause irreversible loss
- Reconstituted in sterile water (no preservative)
- 2–8°C
- 7–10 days maximum
- High
- No
- Shorter shelf life due to lack of antimicrobial agent; single-use preferred
- Room temperature post-reconstitution
- 20–25°C
- <72 hours before significant degradation
- Extreme. Degradation compounds rapidly
- Emergency short-term only; expect 40–60% potency loss within 3 days
- Professional Assessment
- Lyophilised storage is vastly superior for long-term inventory; reconstitute only what you'll use within 28 days and maintain strict 2–8°C refrigeration throughout that window
