- Refrigeration (2–8°C, bacteriostatic water)
- 2–8°C
- 28 days
- >95% bioactivity retained if temperature stable
- Low (benzyl alcohol preservative effective for 4 weeks)
- Standard protocol. Refrigerate immediately after reconstitution and discard on Day 29 regardless of appearance
- Room Temperature (20–25°C)
- 20–25°C
- 24–48 hours maximum
- 15–25% activity loss within 72 hours
- Moderate (bacterial growth accelerates above 15°C)
- Emergency short-term only. If refrigeration unavailable, use within 24 hours and assume reduced potency
- Freezing (−20°C, post-reconstitution)
- −20°C
- Not recommended
- 30–60% activity loss after single freeze-thaw cycle
- Low (freezing inhibits bacterial growth)
- Irreversible denaturation from ice crystal formation. Never freeze reconstituted peptide
- Door Shelf Storage
- 8–12°C
- Accelerated degradation (2× rate per 5°C above 8°C)
- Low to moderate
- Temperature fluctuations with door opening exceed safe range. Use back of middle shelf only
- Refrigeration at 2–8°C with bacteriostatic water is the only validated storage method that maintains both peptide bioactivity and sterility for the standard 28-day research window. All other conditions either accelerate degradation or introduce contamination risk that compromises experimental reliability.
