What this means

  • 01

    No product containing Orexin-A is approved by FDA for any use in the United States. So nothing on sale is allowed for use in people.

  • 02

    "Research use only" is a label sellers put on. It is not a legal category that allows use in people, and it does not get a product out of medicines law.

  • 03

    Importing it, supplying it or promoting it for use in people can fall under medicines law in the United States. This page is general information, not legal advice.

What Orexin-A is

Orexin-A is the brain chemical that keeps you awake. It is sold as a nose spray for alertness, after a monkey study found a nose spray reversed the effects of lost sleep. The only human data are small studies in narcolepsy. Approved narcolepsy drugs are small-molecule pills, not this peptide.

Orexin-A controls how awake you are, through two receptors in the brain. Losing it causes narcolepsy.

How it works: It switches on two orexin receptors in the brain, which keep you awake and alert.

Approval history: Not approved

How FDA treats this kind of product

Approves prescription drugs, each for a named use. It also acts against unapproved products, including peptides sold online. Compounding pharmacies, which mix drugs to order, may make some compounds with a prescription. That only applies when the FDA puts the compound in a category of bulk ingredients it allows.

The legal category above is how The Longevity Archive reads U.S. Food and Drug Administration listings for Orexin-A on the reviewed date. It is not a legal opinion. Rules change. Bringing a compound into the country, prescribing it and owning it can each be treated differently. Check with the agency before you act on anything here.

Orexin-A in sport and the military

Whether Orexin-A is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United States. Before you compete or get tested, look up Orexin-A by name on the Prohibited List, or look up a named product in Global DRO. Under the World Anti-Doping Code, category S0 bans, at all times, any drug-like substance that meets two tests. No other section of the List covers it. And no government health regulator anywhere has a current approval for it as a treatment in people. Many substances that are approved somewhere are banned by name in another section. So approval does not mean a substance is allowed in sport.

The rules you compete or serve under decide this, not this page.
