Orexin-A 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) Orexin-A 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 Orexin-A?
Proper storage is critical for maintaining Orexin-A's potency and safety. As a Neuropeptide hormone, Orexin-A is sensitive to heat, light, and moisture — improper storage can render it ineffective or harmful.
How Do You Store Lyophilized Orexin-A?
Unreconstituted (freeze-dried) Orexin-A: 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 Orexin-A?
After mixing with bacteriostatic water: Store at 2-8°C (standard refrigerator). Use within 4-6 weeks for optimal potency.
Never freeze reconstituted Orexin-A. 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 Orexin-A Has Gone Bad?
Reconstituted Orexin-A 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 Orexin-A?
Lyophilized Orexin-A can be shipped with cold packs and insulation. For short trips, a small cooler bag with an ice pack maintains adequate temperature.
Reconstituted Orexin-A is more temperature-sensitive and should be kept refrigerated during travel if possible.
Bottom Line on Orexin-A 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.

Frequently Asked Questions
What is Orexin-A?
Orexin-A (Hypocretin-1) is a Neuropeptide hormone. Naturally occurring peptide synthesized in the hypothalamus, regulating sleep-wake cycles and arousal. It is researched for increased wakefulness and arousal, cognitive function in narcolepsy, pain modulation.
What is the recommended Orexin-A dosage?
Common dosages: not established for human peptide administration administered single dose in research protocols via intranasal (experimental human), intracerebroventricular (animal studies). Cycle length: single dose protocols; no established multi-week cycles. Half-life: rapidly degraded peripherally; central CSF half-life estimated 10-30 minutes. Use our peptide calculator for exact reconstitution math.
What are the side effects of Orexin-A?
Limited human safety data. Potential increased heart rate and blood pressure. Poor blood-brain-barrier penetration limits peripheral dosing.
Is Orexin-A safe?
Orexin-A has shown a preliminary safety profile in research. Not FDA-approved. Research use only. Development focus has shifted to small molecule receptor agonists. All research should follow appropriate safety protocols.
