Unreconstituted vs Reconstituted: Two Different Storage Protocols
The temperature requirements for CJC-1295 No DAC and ipamorelin depend entirely on whether the peptide has been reconstituted. This distinction is critical and non-interchangeable. Unreconstituted (Lyophilised Powder): Store at −20°C in a standard freezer. Lyo

- The temperature requirements for CJC-1295 No DAC and ipamorelin depend entirely on whether the peptide has been reconstituted. This distinction is critical and non-interchangeable.
- Unreconstituted (Lyophilised Powder): Store at −20°C in a standard freezer. Lyophilised peptides are stable at this temperature for 24 months from manufacture date. Short-term ambient exposure during shipping (up to 72 hours at temperatures below 30°C) is generally tolerable because the peptides are in a desiccated state with minimal molecular motion. However, prolonged storage at room temperature. Even in powder form. Will gradually reduce potency. If your lyophilised vials arrive warm, transfer them to −20°C storage immediately upon receipt. Do not leave them at room temperature 'until you're ready to use them'. That's how you waste expensive compounds before reconstitution.
- Reconstituted (Mixed with Bacteriostatic Water): Store at 2–8°C (standard refrigerator temperature) immediately after mixing. Do not freeze reconstituted peptides. Freezing causes ice crystal formation that physically disrupts the peptide structure, leading to aggregation and precipitation upon thawing. The 28-day stability window at 2–8°C is a manufacturer-tested standard for bacteriostatic water solutions; beyond 28 days, bacterial growth becomes a contamination risk even if the peptide itself remains chemically stable. Mark your reconstitution date on the vial and discard any solution older than four weeks, regardless of appearance.
- Our experience working with research labs shows that the most common storage error is leaving reconstituted vials at room temperature between doses. Researchers remove the vial from the fridge, draw their dose, then leave it on the bench while preparing the injection. Sometimes for 20–30 minutes. While a single 30-minute excursion won't destroy the peptide, repeated exposure adds up. Each time the vial warms above 8°C, the degradation clock accelerates. We recommend a strict protocol: remove the vial, draw immediately, return to the fridge within 60 seconds. The peptide in the syringe is already at room temperature and will be used within minutes, so that portion doesn't require refrigeration. But the remaining solution in the vial does.
