Pinealon Storage: Refrigerator vs. Freezer Comparison
Choosing the right storage method depends entirely on whether your Pinealon is lyophilised powder or reconstituted solution. The following table clarifies the specific requirements, risks, and appropriate use cases for each storage zone. | Storage Method | Tem

- Choosing the right storage method depends entirely on whether your Pinealon is lyophilised powder or reconstituted solution. The following table clarifies the specific requirements, risks, and appropriate use cases for each storage zone.
- | Storage Method | Temperature Range | Suitable for Lyophilised Powder | Suitable for Reconstituted Solution | Stability Duration | Primary Risk | Bottom Line ||—|—|—|—|—|—|| Freezer (−20°C) | −15°C to −25°C | Yes. Optimal long-term storage | No. Freezing causes ice crystal formation and peptide aggregation | 24–36 months (lyophilised) | Moisture absorption during freeze-thaw cycles | Use for unopened vials only; never freeze reconstituted peptides || Refrigerator (2–8°C) | 2°C to 8°C | Acceptable for short-term (<7 days) | Yes. Required storage method | Up to 28 days (reconstituted) | Temperature excursions above 8°C during door openings | The only safe storage method for mixed peptides; verify temperature daily || Room Temperature (20–25°C) | 18°C to 25°C | Emergency only (<24 hours) | No. Degradation begins within hours | <24 hours | Rapid peptide bond hydrolysis and bacterial growth | Acceptable only for lyophilised powder in sealed vials during shipping or temporary handling |
- The table makes the distinction clear: freezer storage is mandatory for lyophilised Pinealon, and refrigerator storage is mandatory for reconstituted Pinealon. The two are not interchangeable, and violating this rule is the most common cause of total peptide loss in research settings.
