Is Enobosarm legal in the United Kingdom?

The drug sold on the grey market as ostarine. In proper studies, 3 mg added to semaglutide cut muscle loss by 71 percent in adults over 60.

Enobosarm switches on the androgen (male hormone) receptor, mainly in muscle and bone. It failed earlier programs in cancer-related muscle wasting.

How it works: It switches on the androgen receptor mostly in muscle and bone. That helps build muscle protein, with less effect on the prostate and skin than testosterone.

Approval history: Investigational; not approved for any use. SARMs are lab-made drugs that act like testosterone. Unapproved SARM products are illegal to sell as supplements.

Licenses medicines for sale in the UK. A compound without a licence to be sold (a marketing authorisation) is an unlicensed medicine. The law only lets it reach people through a prescriber, under the specials scheme (unlicensed medicines made for one patient's needs). It cannot be sold as a research product.

The legal category above is how The Longevity Archive reads Medicines and Healthcare products Regulatory Agency listings for Enobosarm on the reviewed date. It is not a legal opinion. Rules change.

Whether Enobosarm is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in the United Kingdom. Before you compete or get tested, look up Enobosarm 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.
