- Lyophilized powder (freezer)
- −20°C
- 12–24 months
- Temperature cycling during retrieval; condensation from repeated freeze-thaw
- Gold standard for long-term storage. Minimizes degradation by removing water entirely
- Reconstituted solution (refrigerator)
- 2–8°C
- 28 days maximum
- Light exposure; bacterial contamination from multi-draw; temperature excursions if door left open
- Standard for active research protocols. Requires strict sterile technique and light protection
- Room temperature (lyophilized)
- 20–25°C
- 24–48 hours
- Accelerated hydrolysis; moisture absorption from ambient humidity
- Emergency short-term only. Not viable for routine storage
- Room temperature (reconstituted)
- <24 hours
- Rapid potency loss; bacterial growth if bacteriostatic water concentration insufficient
- Never store reconstituted peptides at room temp. Degradation begins within hours
