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.
Orexin-A (Hypocretin-1) is a Neuropeptide hormone researched for increased wakefulness and arousal, cognitive function in narcolepsy, pain modulation. Common dosages range from not established for human peptide administration administered single dose in research protocols. Below are the most frequently asked questions.
Frequently Asked Questions About Orexin-A
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 range from not established for human peptide administration, administered single dose in research protocols via intranasal (experimental human), intracerebroventricular (animal studies). Cycles typically run single dose protocols; no established multi-week cycles.
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 legal?
Not FDA-approved. Research use only. Development focus has shifted to small molecule receptor agonists.
What is the half-life of Orexin-A?
The half-life of Orexin-A is rapidly degraded peripherally; central CSF half-life estimated 10-30 minutes, which determines the single dose in research protocols dosing schedule.
How do you reconstitute Orexin-A?
Add bacteriostatic water to the lyophilized Orexin-A vial. Let the water run down the side — never spray on the powder. Swirl gently. Use our peptide calculator for exact amounts.
Can you stack Orexin-A with other peptides?
Could complement circadian-regulating peptides like DSIP (sleep) for full sleep-wake cycle optimization.
Where can you buy Orexin-A?
Orexin-A is available as a research chemical from vetted suppliers with third-party COA testing.
How long does it take Orexin-A to work?
Initial effects may be noticed within 1-2 weeks, with more significant results typically appearing by weeks 4-8 of a single dose protocols; no established multi-week cycles cycle.
What makes Orexin-A unique?
Unique as a neuropeptide that simultaneously activates multiple arousal neurotransmitter systems — pharmaceutical development has shifted to small molecule agonists due to the peptide's poor peripheral bioavailability.
