- Refrigerated (2–8°C, dark, upright)
- 2–8°C
- 28 days
- Low. Hydrolysis proceeds at baseline rate
- Low. Bacteriostatic water maintains sterility
- This is the standard method for reconstituted peptides. Consistent refrigeration at 4°C preserves structural integrity and bacteriostatic efficacy for the full 28-day window.
- Refrigerated (door storage)
- 4–12°C
- 14–21 days
- Moderate. Temperature fluctuates ±3°C per door opening
- Low
- Acceptable for short-term storage but introduces thermal cycling that accelerates cumulative degradation. Store in main compartment instead.
- Room temperature (20–25°C)
- 20–25°C
- 3–5 days
- High. Hydrolysis rate increases 3–5×
- Moderate. Bacteriostatic efficacy declines faster
- Unsuitable for storage exceeding 72 hours. Use only for active experimental periods where daily dosing occurs.
- Frozen (−20°C, reconstituted)
- −20°C
- Not recommended
- Severe. Ice crystals disrupt peptide backbone
- N/A
- This is structural destruction, not preservation. Never freeze reconstituted peptides.
- Ambient (no refrigeration)
- 15–30°C
- <48 hours
- Severe. Peptide integrity lost within 48–72 hours
- High. Bacterial growth accelerates above 15°C
- Emergency short-term only. Expect significant activity loss if storage extends beyond 24 hours.
