Is Enobosarm legal in Australia?
Written by Aaron CuhaReviewed Sep 2026
Direct answer
Enobosarm is available in Australia only through a prescriber. Its legal category is "Schedule 4 (prescription only); not approved". It is not sold over the counter. Using it rests on the prescriber's judgment, not on an approval to sell it. Vials sold "for research use only" fall outside that route, and the label does not make them legal to use in people. On the evidence, 1 completed human trial is cited on its profile.

A "research use only" label on a vial does not make it legal to use on people.

What this means
- 01
Enobosarm reaches patients in Australia only through a prescriber. Usually that is for one narrow use on its label, or through a compounding pharmacy (a pharmacy that mixes its own version) with a prescription.
- 02
That route rests on the prescriber's judgment. For pharmacy-mixed products, it also rests on the pharmacy's own quality checks, not on an approval of the product for sale.
- 03
Buying it online "for research use only" is outside that route. The label does not make it legal to use in people.
What Enobosarm is
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.
How TGA treats this kind of product
Registers or lists medicines and health products on the ARTG, its official register. It also sorts substances into schedules in the Poisons Standard. Many peptides are Schedule 4 (prescription only). So having them without a prescription, or importing them for yourself, is restricted. That is true even when no product is registered.
The legal category above is how The Longevity Archive reads Therapeutic Goods Administration listings for Enobosarm 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.
Enobosarm in sport and the military
Whether Enobosarm is banned in sport is set by the World Anti-Doping Code and by military rules, not by its legal status in Australia. 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.
