Are peptides legal in Australia? (2026 TGA status)

The short answer

In Australia, therapeutic goods are regulated by the Therapeutic Goods Administration (TGA) under the Therapeutic Goods Act 1989, and substances are scheduled under the Poisons Standard. Many popular research peptides are treated as prescription-only medicines, which means they can lawfully be supplied only on a prescription from a registered practitioner, typically through a compounding pharmacy.

Unlike the UK and US, where the legal question mostly turns on how a product is sold, in Australia possession and importation without authority can themselves be unlawful for scheduled substances.

Scheduling: BPC-157 and other peptides

BPC-157 has been listed in Schedule 4 of the Poisons Standard, the prescription-only schedule, together with Appendix D, since 1 June 2024, following a TGA decision notice of 22 May 2024. Australia was among the first countries to schedule it by name. Other peptides may be caught by existing entries or by the general rules for unapproved therapeutic goods, so the absence of a named entry does not mean a peptide is unregulated.

Very few therapeutic peptides have a registered finished product in Australia, which is why the lawful route for those that are prescribed is usually a compounding pharmacy acting on a prescription.

The 2026 enforcement priority

On 10 June 2026 the TGA added unapproved peptides to its priority compliance areas, alongside weight loss medicines, vapes and sunscreens. It named Melanotan II, retatrutide, BPC-157, GHK-Cu, TB-500 and CJC-1295, and said its response could include seizures, infringement notices and civil or criminal penalties. Earlier in 2026 it issued a safety alert about illegal peptides after reports of severe allergic reactions.

Enforcement has been active: in March 2026 a joint TGA, Australian Border Force and Victoria Police operation seized peptides and steroids with an estimated value above $2 million and led to arrests, and in October 2026 the TGA reported more than $126,000 in infringement notices for unlawful importation and advertising of prescription-only medicines.

What this means for buyers in Australia

Ordering a prescription-only peptide from an overseas website without a prescription can lead to the parcel being seized at the border, a warning or infringement notice, and in some cases further action. A research use only label on the parcel does not change how Australian law treats an imported scheduled substance.

Reading and learning about these compounds is entirely lawful, and this site's compound guides and certificate of analysis explainers are written for that purpose. Anyone in Australia considering a peptide for their own health should speak to a registered doctor or pharmacist.
