Dihexa Storage Method Comparison
Lyophilised (sealed with desiccant) −20°C 12–24 months Peptide bonds remain stable in the absence of water; moisture exposure accelerates degradation even at freezer temp Gold standard for long-term storage. Always purchase lyophilised and reconstitute as need

- Lyophilised (sealed with desiccant)
- −20°C
- 12–24 months
- Peptide bonds remain stable in the absence of water; moisture exposure accelerates degradation even at freezer temp
- Gold standard for long-term storage. Always purchase lyophilised and reconstitute as needed
- Lyophilised (ambient shipping)
- 15–25°C
- 48–72 hours MAX
- Short-term ambient exposure tolerable if total time under 72 hours; exceeding this window begins irreversible degradation
- Acceptable during shipping only. Refrigerate or freeze immediately upon receipt
- Reconstituted (refrigerated)
- 2–8°C
- 28 days
- Bacteriostatic water inhibits bacterial growth but does not prevent peptide aggregation or oxidation beyond 4 weeks
- Standard practice for active research protocols. Reconstitute only what you'll use in one month
- Reconstituted (room temp)
- 20–25°C
- 1–2 hours MAX
- Aggregation and oxidation accelerate rapidly above 8°C; peptide loses measurable potency within 30–60 minutes
- Never leave reconstituted peptides at room temperature. Draw and refrigerate immediately
- Reconstituted (frozen)
- NOT RECOMMENDED
- Freezing aqueous solutions forms ice crystals that physically disrupt peptide structure; thawing does not reverse this damage
- Hard avoid. Freezing reconstituted peptides renders them inactive
