CJC-1295 No DAC vs DAC Variant: Storage Comparison
Lyophilised Storage Temp −20°C long-term; ≤25°C short-term (≤48h) −20°C long-term; ≤25°C short-term (≤72h) Both require freezing for storage beyond 1 month—DAC variant tolerates slightly longer ambient shipping due to DAC conjugate shielding the peptide core R

- Lyophilised Storage Temp
- −20°C long-term; ≤25°C short-term (≤48h)
- −20°C long-term; ≤25°C short-term (≤72h)
- Both require freezing for storage beyond 1 month—DAC variant tolerates slightly longer ambient shipping due to DAC conjugate shielding the peptide core
- Reconstituted Storage Temp
- 2–8°C (refrigeration mandatory)
- No difference—both degrade rapidly above 8°C once in solution
- Reconstituted Shelf Life
- 28 days maximum at 2–8°C
- Same stability window—DAC conjugation extends in vivo half-life, not storage stability
- Freeze-Thaw Tolerance (Reconstituted)
- Zero—never freeze after mixing
- Ice crystals destroy both variants equally—this is a structural limitation, not chemistry-specific
- Temperature Excursion Risk
- High—potency loss begins within 6–8 hours at 20°C
- Moderate—DAC group provides minor shielding, extending room-temp tolerance to ~12 hours
- No DAC variant is more thermally fragile due to exposed peptide chain—requires stricter handling
- Visual Degradation Indicators
- Cloudiness, precipitation, yellow tint
- Both show identical visual breakdown signs—if either looks off, discard it
