- Lyophilised CJC-1295 no DAC and Ipamorelin should be stored at −20°C (−4°F) in a freezer immediately upon receipt. This is the optimal storage condition for preserving peptide integrity long-term. If freezer storage isn't available, refrigeration at 2–8°C is acceptable for short-term storage (up to six months), but −20°C extends shelf life significantly. Keep the vials in their original packaging or a sealed container to prevent moisture absorption. Lyophilised peptides are hygroscopic and will absorb atmospheric water, which initiates degradation even in powder form.
- Once you reconstitute the peptide with bacteriostatic water, transfer the vial to a refrigerator set between 2–8°C within 10 minutes of mixing. Do not freeze reconstituted peptides. Ice crystal formation ruptures peptide bonds and destroys activity entirely. Reconstituted peptides must be used within 28–30 days. After 30 days, even under ideal refrigeration, bacterial growth risk increases and peptide potency declines. Mark the reconstitution date on the vial with a permanent marker.
- Temperature monitoring matters. Most household refrigerators fluctuate between 3–7°C, which is acceptable. Avoid storing peptides in the refrigerator door. Temperature swings are greatest there due to frequent opening. Place vials on a middle shelf toward the back, where temperature remains most stable. If you're storing multiple vials, keep them upright in a small plastic container to prevent tipping and cross-contamination.
