Storing CJC-1295 No Dac: Best Practices

Lyophilized Powder

Store at -20°C for long-term stability. The lyophilized form is stable at refrigerated temperatures (2–8°C) or even room temperature for shorter periods but should be kept sealed, away from moisture and direct light for optimal preservation.

Reconstituted Solution

Reconstitute with bacteriostatic water (preferred for multi-use) or sterile water for injection. Once reconstituted, refrigerate at 2–8°C and use within 14–28 days depending on the solvent used and storage conditions. Bacteriostatic water generally allows longer storage compared to sterile water.

Handling

White to off-white lyophilized powder. When reconstituting, inject the solvent slowly down the side of the vial and swirl gently — do NOT shake, as this may damage the peptide structure. Purity: ≥98% by RP-HPLC. Identity: LC-MS/MS (~3367.95 Da). The tetrasubstitution modifications provide resistance to DPP-4 enzymatic degradation, extending functional half-life to approximately 30 minutes from the mere minutes characteristic of native GHRH.
