Tesamorelin Storage: Lyophilised vs Reconstituted Comparison
Tesamorelin storage requirements differ sharply depending on the peptide's state. The table below compares stability, temperature requirements, and viability windows for lyophilised versus reconstituted tesamorelin. Lyophilised (unreconstituted) −20°C (freezer
This comparison does not assign a generated winner or score.
- Tesamorelin storage requirements differ sharply depending on the peptide's state. The table below compares stability, temperature requirements, and viability windows for lyophilised versus reconstituted tesamorelin.
- Lyophilised (unreconstituted)
- −20°C (freezer)
- 24–36 months (sealed vial)
- Freeze-thaw cycles, moisture infiltration
- Moderate (minimize light exposure)
- Maximum stability. Store long-term at −20°C, remove only when ready to reconstitute
- Reconstituted (mixed with bacteriostatic water)
- 2–8°C (refrigerator)
- 28 days maximum
- Temperature excursions above 8°C, aggregation, oxidation
- High (store in amber vial or wrap in foil)
- Strict cold chain required. Any excursion above 8°C risks irreversible aggregation
- Ambient storage (lyophilised, emergency)
- 20–25°C (room temperature)
- 72 hours maximum (sealed vial)
- Hydrolysis, oxidation (accelerated)
- High
- Temporary only. Transfer to −20°C immediately upon receipt
- Frozen reconstituted (incorrect)
- Below 0°C
- Not applicable. Ice crystals rupture peptide structure
- Ice crystal formation
- Not applicable
- Never freeze reconstituted peptides. This is a total loss scenario
- The lyophilised state offers the longest stability window, but that window closes permanently once reconstitution occurs. Researchers who reconstitute entire multi-dose vials and then fail to use them within 28 days lose the unused portion. Partial reconstitution is not feasible with standard vial formats.
