Description
Orexin A Spray provides the wake-promoting neuropeptide orexin-A in a ready-to-use intranasal research format. Limitless Life Nootropics prepares each 5mg bottle in the USA.
What Is Orexin A Spray?
Orexin-A, also called hypocretin-1, was discovered in 1998 by two independent research groups. It is a 33-amino-acid peptide with two disulfide bonds, produced by a small population of neurons in the lateral hypothalamus. It acts on two receptors, OX1R and OX2R.
Loss of orexin-producing neurons is the cause of narcolepsy type 1, which revealed the peptide’s central role in maintaining wakefulness. Research has since linked it to appetite, energy expenditure, reward and attention. Animal studies have examined intranasal delivery as a way to deliver the peptide to the brain.
Each bottle contains 5mg in a ready-to-use solution.
Areas of Scientific Investigation
Laboratory studies have explored this spray across several areas of investigation:
- Wakefulness and sleep–wake stability
- Narcolepsy and sleep deprivation models
- OX1R and OX2R receptor signaling
- Appetite and energy balance
- Attention and cognitive performance
Researchers can review peer-reviewed studies on orexin-A through the National Library of Medicine (PubMed) database.
