SS-LUP-332 Storage: Reconstituted vs Lyophilised Peptide Comparison
The storage requirements for SS-LUP-332 depend entirely on whether the peptide is in lyophilised (freeze-dried) powder form or reconstituted solution. The table below summarises the critical differences. Lyophilised Powder (Unopened) −20°C or lower 12–24 month
No winner is assigned.

- The storage requirements for SS-LUP-332 depend entirely on whether the peptide is in lyophilised (freeze-dried) powder form or reconstituted solution. The table below summarises the critical differences.
- Lyophilised Powder (Unopened)
- −20°C or lower
- 12–24 months
- −15°C to −25°C (brief excursions tolerable)
- Moisture absorption accelerates degradation; potency drops 10–20% per month at room temperature
- Freezer storage is mandatory for long-term stability. Room temperature storage destroys potency within weeks
- Reconstituted with Bacteriostatic Water
- 2–8°C (refrigeration)
- 28 days
- 2–8°C (no excursions above 10°C)
- Hydrolysis and oxidation accelerate; 30–50% potency loss within 7–14 days at 25°C
- Refrigeration is non-negotiable. Even brief warm exposure causes irreversible degradation
- Reconstituted, Frozen (Not Recommended)
- Not applicable
- N/A
- Ice crystal formation physically disrupts protein structure; potency reduced by 40–70% on first thaw
- Never refreeze reconstituted peptides. Freeze-thaw cycles destroy bioavailability
- The data makes the rule clear: lyophilised SS-LUP-332 belongs in the freezer until reconstitution; reconstituted SS-LUP-332 belongs in the refrigerator and must be used within 28 days. There are no shortcuts.
