- Before reconstituting CJC-1295 lyophilized powder, understanding the differences between storage states, reconstitution solvents, and handling protocols prevents the most common errors that compromise peptide integrity.
- Lyophilised (unreconstituted)
- −20°C (standard freezer)
- 24 months
- Moisture exposure, freeze-thaw cycles, frost-free defrost fluctuations
- Optimal long-term storage; minimal degradation if kept sealed and frozen
- Reconstituted with bacteriostatic water
- 2–8°C (refrigerator)
- 28 days
- Temperature excursions above 8°C, repeated freeze-thaw, contamination from vial access
- Standard research protocol; potency guaranteed within 28 days if refrigerated continuously
- Reconstituted with sterile water (no preservative)
- 72 hours maximum
- Rapid bacterial growth, no benzyl alcohol preservative
- Not recommended. Bacterial contamination risk too high for multi-dose vials
- Room temperature exposure (reconstituted)
- 20–25°C
- <7 days (accelerated degradation)
- Oxidative degradation of methionine residues, peptide bond hydrolysis
- Potency drops 15–20% per week at room temp. Avoid entirely
