What this means

No product containing Bradykinin 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 Bradykinin is
Bradykinin is a small inflammation signal, not a treatment. It is the reason some blood pressure pills cause a cough and face swelling. Human studies of blood flow and nerve tissue have measured what it does. There is no medical use for giving it.
Bradykinin is a small signal, 9 building blocks long. Enzymes release it from a larger protein during inflammation and injury.
How it works: In people, bradykinin works through two receptors. B2 is always there.
Approval history: Not an approved drug. Bradykinin is a signal the body makes, and a chemical used in labs. No bradykinin product showed up in our checks of the FDA drug database (Drugs@FDA). The approved medicine that works on this system is icatibant, which blocks bradykinin's B2 receptor.
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 Bradykinin 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.
Bradykinin in sport and the military
Whether Bradykinin 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 Bradykinin 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.

- Global DRO (check a named product)

- Operation Supplement Safety (US service members)
