SS-31 is a research compound. It is not approved by the FDA or any regulatory body for human use. This article is for educational and informational purposes only. Nothing here constitutes medical advice. Consult a qualified physician before considering any peptide use.
Lyophilized (freeze-dried) SS-31 should be stored at -20°C for long-term stability. Once reconstituted with bacteriostatic water, store at 2-8°C (refrigerated) and use within 4-6 weeks. Never freeze reconstituted peptides.
How Do You Store SS-31?
Proper storage is critical for maintaining SS-31's potency and safety. As a Mitochondrial-targeting tetrapeptide, SS-31 is sensitive to heat, light, and moisture — improper storage can render it ineffective or harmful.
How Do You Store Lyophilized SS-31?
Unreconstituted (freeze-dried) SS-31: Store at -20°C (standard freezer) for maximum shelf life of 12-24+ months. Keep the vial sealed and away from moisture.
Room temperature storage is acceptable for short periods (shipping) but degrades potency over weeks. Refrigerator (2-8°C) storage extends this to several months.
How Do You Store Reconstituted SS-31?
After mixing with bacteriostatic water: Store at 2-8°C (standard refrigerator). Use within 4-6 weeks for optimal potency.
Never freeze reconstituted SS-31. Freezing and thawing damages the peptide structure. The bacteriostatic water's benzyl alcohol preservative is what allows the 4-6 week window — sterile water would give you only days.
Keep the vial upright and away from the refrigerator door (temperature fluctuations from opening/closing).
How Do You Know if SS-31 Has Gone Bad?
Reconstituted SS-31 should be clear and colorless. If you see cloudiness, particles, or discoloration — discard it. These indicate bacterial contamination or peptide degradation.
If stored properly, degradation is gradual and may not be visually apparent. This is why the 4-6 week window for reconstituted peptides exists.
Can You Travel With SS-31?
Lyophilized SS-31 can be shipped with cold packs and insulation. For short trips, a small cooler bag with an ice pack maintains adequate temperature.
Reconstituted SS-31 is more temperature-sensitive and should be kept refrigerated during travel if possible.
Bottom Line on SS-31 Storage
Freeze-dried: -20°C, sealed, 12+ months. Reconstituted: 2-8°C, use within 4-6 weeks, never freeze. Source from vendors who ship with proper cold-chain packaging.
