- 2–8°C refrigerated, dark, sealed vial
- 28 days at >95% potency
- Slow hydrolysis of peptide bonds; minimal oxidation
- Ideal for multi-dose vials across a standard research cycle
- This is the baseline standard. Deviations reduce usable lifespan dramatically
- 2–8°C refrigerated, clear vial, repeated light exposure
- 18–21 days at >90% potency
- Photodegradation of tryptophan residues; accelerated oxidation cascade
- Acceptable for short studies but not recommended for extended protocols
- Light exposure is underestimated. Wrap in foil or switch to amber glass
- 20–25°C room temperature, sealed, dark
- 3–5 days at >85% potency
- Rapid hydrolysis; peptide backbone cleavage at labile bonds
- Emergency short-term only. Not viable for planned storage
- One weekend at room temp doesn't destroy the vial, but don't rely on this
- Above 30°C (shipping delays, summer car storage)
- <24 hours before significant loss
- Irreversible aggregation and denaturation; complete structural collapse
- Protocol failure. Peptide is non-functional even if appearance unchanged
- High-heat excursions are unrecoverable. Assume total loss if this occurs
- Frozen (−20°C) after reconstitution
- Not recommended. Ice crystal damage
- Mechanical shearing from ice expansion; phase separation on thaw
- Freezing reconstituted peptides is not the same as storing lyophilised powder
- Never freeze a reconstituted vial. Degradation is immediate and permanent
- Refrigerated with repeated freeze-thaw cycles
- <7 days per cycle
- Cumulative mechanical and osmotic stress; protein aggregation
- Power outages or fridge malfunctions create this scenario unintentionally
- If a vial thaws even once, use it within the week or discard it
