This comparison does not assign a generated winner or score.
- 2–8°C, protected from light, <10 punctures
- 28 days
- <5% loss at day 28
- Optimal for full therapeutic window. Industry standard
- 2–8°C, exposed to fluorescent light, frequent handling
- 21 days
- 8–12% loss at day 21
- Acceptable if vial turnover is fast; wrap in foil to extend
- 10–15°C (top refrigerator shelf or door storage)
- 14–18 days
- 15–20% loss at day 18
- Non-compliant. Peptide aggregates faster; move to colder zone
- Room temperature (20–25°C) for >24 hours
- 7–10 days
- 25–35% loss at day 10
- Significant potency loss; discard if left out overnight
- Freeze-thaw cycled (frozen after reconstitution)
- Not recommended
- >40% loss after one freeze-thaw
- Aggregation irreversible. Never freeze reconstituted peptides
