- Lyophilised powder (unreconstituted)
- −20°C (standard freezer)
- 12–24 months (manufacturer-dependent)
- Sealed amber glass vial with desiccant
- Must be protected. Amber glass preferred
- This is the safest storage state. Freeze-dried peptides tolerate minor temperature fluctuations during shipping better than reconstituted solutions, but long-term freezer storage at consistent −20°C is non-negotiable for multi-month stability.
- Reconstituted solution (mixed with bacteriostatic water)
- 2–8°C (refrigerator, not freezer)
- 28 days maximum
- Sterile glass vial with rubber stopper
- Must be refrigerated in opaque container or wrapped in foil
- Stability drops the moment water is added. The 28-day window assumes perfect refrigeration. Any temperature spike above 8°C shortens this. Freezing reconstituted peptides causes ice crystal formation that physically damages protein structure, so never freeze a mixed vial.
- Room temperature exposure (shipping, travel, accidental)
- 20–25°C
- 24–48 hours (lyophilised), 4–8 hours (reconstituted)
- Original packaging
- Minimal impact compared to heat
- Lyophilised peptides can survive brief ambient exposure during express shipping if insulated properly. Reconstituted vials cannot. Any duration above 10°C begins degradation. Use insulated medical coolers with cold packs rated for 36+ hour stability if traveling.
