Are research peptides legal in Australia without a licence?

Unscheduled research peptides may be purchased without a licence, but scheduled ones, including BPC-157, thymosin beta-4 and AOD-9604, may be possessed only under an authority issued by the relevant state or territory. No research peptide may be supplied for human therapeutic use without ARTG registration. Macropus Peptides supplies all compounds for in-vitro research by adults aged 18 or older.

What does Schedule 4 mean for a research peptide?

Schedule 4 means the substance should be available only through an authorised practitioner, and that supply and possession outside that pathway are controlled by state and territory law. For a laboratory, it means the compound may be held only under a research, teaching or analytical authority issued in its jurisdiction. Schedule 4 status does not make a compound illegal to study, only regulated.

Are research peptides permitted in sport?

The World Anti-Doping Code bans most research peptides at all times, in and out of competition. Unapproved substances fall under the non-approved substances class, and thymosin beta-4 is listed with growth factors and related substances. Athletes subject to testing should avoid all contact with these compounds. Research laboratories are not bound by the Code, but staff who compete should be aware of it.

Does buying from an Australian supplier make a peptide legal to hold?

No, buying from an Australian supplier does not by itself make a scheduled peptide legal to hold. Local supply avoids the Customs import permit requirement, but state and territory poisons law still decides who may possess a Schedule 4 or Appendix D substance. The buyer remains responsible for holding the appropriate authority before an order is placed.

Where can the current Poisons Standard be checked?

The current Poisons Standard is published on the Federal Register of Legislation, and the TGA website lists scheduling decisions, interim and final, as they are made. State and territory health departments publish their own poisons legislation and licensing requirements. Checking all three sources before ordering gives the most reliable picture, because amendments can take effect between editions.

Are Research Peptides Legal in Australia?

Q: What is Appendix D of the Poisons Standard?

Appendix D lists Schedule 4 substances that carry additional controls on possession or supply. Item 5 covers substances, including thymosin beta-4, for which possession without authority is itself an offence under state law. A laboratory holding an Appendix D item therefore needs an authority that covers possession specifically, in addition to one covering its intended research.

Research peptides are not banned as a class in Australia, but none is approved as a medicine, and many are scheduled substances whose supply and possession are controlled by state and territory poisons laws. BPC-157, for example, has had its own Schedule 4 entry in the Poisons Standard since 1 June 2024. The legal position of each compound depends on its schedule, so the rules must be checked peptide by peptide.

Macropus Peptides supplies adults aged 18 or older for in-vitro laboratory research only, under the terms of our research-use policy. What follows is a plain-language outline of the regulatory framework as we understand it in September 2026. It is general information, not legal advice, and scheduling decisions change.

How Does Australia Regulate Research Peptides?

Australia regulates research peptides through three separate layers: therapeutic goods law administered by the TGA, the national Poisons Standard, and the poisons legislation of each state and territory.

The TGA and the ARTG

The Therapeutic Goods Administration administers the Therapeutic Goods Act 1989. With limited exceptions, any product supplied for therapeutic use in Australia must first be entered in the ARTG (Australian Register of Therapeutic Goods). None of the research peptides discussed here holds an ARTG entry, so none may be marketed or supplied as a medicine, supplement or therapy.

The Poisons Standard

The Standard for the Uniform Scheduling of Medicines and Poisons, known as the Poisons Standard or SUSMP, classifies substances into schedules. Schedule 4 covers substances that should be available only through an authorised medical practitioner, dentist or other authorised health practitioner. Appendix D sets additional controls, and item 5 of Appendix D covers substances for which possession without authority is itself an offence under state law.

State and territory poisons laws

The Poisons Standard has no force on its own. Each state and territory adopts it through its own legislation, such as the Medicines and Poisons Act 2019 in Queensland or the Poisons and Therapeutic Goods Act 1966 in New South Wales. Those Acts determine who may hold a scheduled substance, and most provide licences or authorities for research, teaching and analytical work. That is the pathway through which laboratories hold Schedule 4 compounds lawfully.

Is BPC-157 Legal in Australia?

BPC-157 is legal to hold in Australia only with an authority under state or territory poisons law, because it has been a Schedule 4 substance since 1 June 2024 and has no ARTG entry. It is a synthetic peptide of 15 amino acids with no registration as a medicine in any country. After the TGA received numerous import referrals, the scheduling committees considered it in November 2023, and the final decision created the Schedule 4 entry. Sources written before June 2024 describe it as unscheduled and are now out of date.

For a university or commercial laboratory, the practical questions are whether its state authority covers Schedule 4 research substances and whether its institution has approved the work. Our BPC-157 research vials in 5mg and 10mg are supplied on that basis only.

Is Thymosin Beta-4 Legal in Australia?

Thymosin beta-4 is a Schedule 4 substance also listed in Appendix D, so possessing it without an authority is an offence under state law. The native protein has 43 amino acids, and TB-500 is the name used for a synthetic peptide based on its active region. The Appendix D listing places it among the performance and image enhancing substances, and the World Anti-Doping Code prohibits it within growth factors and related substances. Our TB-500 peptide for in-vitro study is subject to the same checks as BPC-157, plus the additional Appendix D control.

Is AOD-9604 Legal in Australia?

AOD-9604 is a Schedule 4 substance in Australia, placed there by a scheduling delegate decision in 2015, and it has no ARTG entry. It is a 16 residue fragment of human growth hormone first developed in Melbourne, and its clinical development ended after phase 2b trials. A food-ingredient notification in the United States is sometimes cited online, but it has no bearing on Australian scheduling. The molecule itself is described in what AOD-9604 is and how it was studied, and our AOD-9604 2mg and 5mg vials are supplied as research material only.

Is DSIP Legal in Australia?

DSIP has no ARTG entry and no named entry that we could locate in the Poisons Standard index, but that absence does not establish that it is unrestricted. Delta sleep-inducing peptide is a nine residue neuropeptide first isolated in 1977. Group entries, the general provisions for unapproved therapeutic goods and state legislation can all still apply. Consult the current consolidated Poisons Standard and the relevant state health department before assuming any compound is free of controls.

Regulatory Status at a Glance

Compound	ARTG entry	Poisons Standard, our reading September 2026	Sport	What to check
BPC-157	None	Schedule 4 from 1 June 2024	Prohibited as a non-approved substance	State authority for Schedule 4 research
Thymosin beta-4 and TB-500	None	Schedule 4 and Appendix D item 5	Prohibited	Authority to possess, not only to use
AOD-9604	None	Schedule 4 since 2015	Prohibited as a non-approved substance	State authority for Schedule 4 research
DSIP	None	No named entry found	Check the current prohibited list	Group entries and state law

Schedules are amended after each round of committee meetings. The table is a starting point for a compliance check, never its conclusion.

Can Research Peptides Be Imported Into Australia?

Many research peptides can be imported into Australia only with a permit from the Office of Drug Control, because hormone-related compounds fall under the Customs (Prohibited Imports) Regulations 1956. Growth hormone secretagogues and thymosin beta-4 are among them, and overseas parcels without a permit are routinely seized. Supply from Australian stock removes the import step, although state poisons law still governs possession. Our research peptide catalogue is dispatched within Australia with tracking.
