This comparison does not assign a generated winner or score.
- Lyophilised (sealed vial)
- −20°C
- 12–24 months from synthesis
- None recommended (store continuously frozen)
- No visual signal. Potency confirmed via HPLC only
- Gold standard for long-term storage; avoid room-temperature excursions >72 hours even in powder form
- Reconstituted (bacteriostatic water)
- 2–8°C
- 28 days
- Zero. First freeze-thaw reduces potency 8–12%
- Remains clear; degradation invisible without assay
- Use staged reconstitution for multi-month studies; do not freeze after mixing
- Reconstituted (sterile water)
- 72 hours
- Zero
- Remains clear; bacterial growth risk after 72h without preservative
- Only for single-use or immediate protocols; no multi-dose viability
- Room temperature (reconstituted)
- 20–25°C
- <48 hours before >10% potency loss
- N/A. Discard after room-temp exposure
- No visible change; peptide structure unfolds
- Emergency transport only; refrigerate within 4 hours of removal from cold storage
