Does Sermorelin Need Refrigeration Storage?: Temperature Comparison
Deep Freeze Lyophilised −20°C to −80°C 24–36 months Fully preserved. Peptide locked in solid state with no molecular motion Gold standard for long-term storage; required before reconstitution Standard Refrigeration Reconstituted 2–8°C 28 days Alpha-helix maint

- Deep Freeze
- Lyophilised
- −20°C to −80°C
- 24–36 months
- Fully preserved. Peptide locked in solid state with no molecular motion
- Gold standard for long-term storage; required before reconstitution
- Standard Refrigeration
- Reconstituted
- 2–8°C
- 28 days
- Alpha-helix maintained; hydrogen bonds stable at reduced thermal energy
- Mandatory post-reconstitution; only condition that preserves potency for multi-dose use
- Room Temperature
- 20–25°C
- 48–72 hours
- Rapid tertiary structure loss; 40% activity decline within 72 hours
- Unacceptable for storage; brief exposure during dosing is tolerable
- Elevated Temperature
- Either form
- >30°C
- <24 hours
- Irreversible denaturation; peptide unfolds and aggregates within hours
- Complete loss of biological activity; cannot be recovered by refrigeration
- Freeze-Thaw Cycle
- Repeated freezing/thawing
- Immediate degradation
- Ice crystals fracture peptide; precipitation visible after first thaw
- Never freeze reconstituted sermorelin under any circumstance
