Is Cardarine legal in the United States?

Cardarine is a drug GSK stopped developing, reportedly after long rodent studies found cancers in many organs. It is still sold widely for endurance and fat loss, despite that report and a ban in sport.

Cardarine pushes muscle to burn more fat. It was tested in people.

How it works: It switches on PPAR-delta, a gene switch that turns up fat burning in muscle.

Approval history: Never approved; work on it stopped over cancer risk

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 Cardarine 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.

Whether Cardarine 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 Cardarine 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.
