Australian legal status
Are peptides legal in Australia?
Short answer
Almost none of the peptides sold online can be bought legally in Australia without a prescription, and for many of them holding the vial is an offence in itself, separate from anything the seller did.
A few, like semaglutide, are approved medicines you can be prescribed. A second group is prescription only. A third group carries an extra restriction that most websites do not mention at all. The table below gives the status of each compound, checked against the Poisons Standard on 1 August 2026.
Why do some peptides carry a possession offence?
Some peptides carry a possession offence because they appear in Appendix D of the Poisons Standard as well as Schedule 4. Schedule 4 controls supply, so a pharmacist dispenses it and a doctor prescribes it. Appendix D goes further. Clause 5 of that appendix is headed "Poisons for which possession without authority is illegal", and the table under it names the substances "that must not be possessed by a person without authority".
BPC-157, TB-500, CJC-1295, ipamorelin, AOD-9604, hexarelin, follistatin and thymosin beta-4 are all in that table, along with growth hormone secretagogues and growth hormone releasing peptides as whole classes. So are anabolic steroids, which is the company these compounds keep in Australian law.
The practical difference matters to anyone who has already bought something. With a Schedule 4 substance that is not in Appendix D, the legal problem sits with whoever supplied it. With a Schedule 4 substance that is in Appendix D, a problem attaches to the person holding it. Most pages answering this question flatten both into "you need a prescription", which is true and incomplete. These are the four tiers.
Approved medicine
A doctor can prescribe it and a pharmacy can dispense it.
Semaglutide, tirzepatide
Schedule 4 only
Prescription only. Supply without one is unlawful, but possession alone is not a separate offence.
Melanotan II, sermorelin
Schedule 4 plus Appendix D
Prescription only, and holding it without a prescription is itself an offence.
BPC-157, TB-500, CJC-1295, ipamorelin
Not scheduled
Not named in the Poisons Standard. Still not an approved medicine, so it cannot lawfully be supplied for human use.
GHK-Cu, MOTS-c, PT-141, retatrutide
Which peptides are legal in Australia?
No peptide in this table is legal to buy without a prescription. 7 of the 15 listed are also illegal to possess without one. Each status was read from the Poisons Standard itself rather than from another website, and each links to a page explaining what the status means for that compound.
| Compound | Status in Australia | Schedule | What that means |
|---|---|---|---|
| AOD-9604CAS 221231-10-3 | Illegal to possess without a script | Schedule 4, Appendix D clause 5 | Named individually by CAS number and listed in Appendix D clause 5, so possession without a prescription is an offence. |
| BPC-157Body Protection Compound 157 | Illegal to possess without a script | Schedule 4, Appendix D clause 5 | Prescription only, and listed in Appendix D clause 5, which covers poisons a person must not possess without authority. Holding it without a prescription is an offence in itself, not just a supply problem. |
| CJC-1295CAS 863288-34-0 | Illegal to possess without a script | Schedule 4, Appendix D clause 5 | Named individually in Schedule 4 by CAS number, and in Appendix D clause 5, so possession without a prescription is an offence. Growth hormone releasing hormones are also captured as a class. |
| FollistatinFollistatin 344 | Illegal to possess without a script | Schedule 4, Appendix D clause 5 | Listed in Appendix D clause 5, so possession without a prescription is an offence. |
| GHK-CuCopper peptide | Not specifically scheduled | Not named in the Poisons Standard | GHK and GHK-Cu are not named anywhere in the June 2026 Poisons Standard. That is not the same as being approved or unregulated: an unscheduled substance can still be an unapproved therapeutic good, and how it is sold and what is claimed for it both matter. |
| Hexarelin | Illegal to possess without a script | Schedule 4, Appendix D clause 5 | Prescription only and listed in Appendix D clause 5, so possession without a prescription is an offence. |
| Ipamorelin | Illegal to possess without a script | Schedule 4, Appendix D clause 5 | Prescription only and listed in Appendix D clause 5, so possession without a prescription is an offence. Growth hormone secretagogues are captured as a class as well. |
| Melanotan IIMT-II | Prescription only | Schedule 4 | Prescription only. It is listed in Schedule 4 and is NOT in Appendix D clause 5, so it does not carry the possession offence that applies to BPC-157 or TB-500. Several sites report it as Schedule 9 or prohibited. That is wrong as at the June 2026 Poisons Standard. |
| MOTS-c | Not specifically scheduled | Not named in the Poisons Standard | Not named in the June 2026 Poisons Standard. Unscheduled does not mean approved or unregulated, and an unapproved therapeutic good is still regulated by other parts of the Act. |
| PT-141Bremelanotide | Not specifically scheduled | Not named in the Poisons Standard | Neither PT-141 nor bremelanotide is named in the June 2026 Poisons Standard. Unscheduled does not mean approved: it is not an approved medicine in Australia and supply for human use still engages the Therapeutic Goods Act. |
| RetatrutideLY3437943 | Not specifically scheduled | Not named in the Poisons Standard | Not named anywhere in the June 2026 Poisons Standard, because it is still investigational and not approved as a medicine in Australia or anywhere else. Unscheduled is not a loophole here: an unapproved therapeutic good cannot lawfully be supplied for human use, so anything sold as retatrutide is outside the approved supply chain entirely. |
| SemaglutideOzempic | Approved, prescription needed | Schedule 4 | Prescription only. An approved medicine in Australia, so a doctor can prescribe it and a pharmacy can dispense it. Not in Appendix D clause 5, so it does not carry the possession offence that applies to most research peptides. |
| Sermorelin | Prescription only | Schedule 4 | Prescription only. Listed in Schedule 4 in its own right and not in Appendix D clause 5. |
| TB-500Thymosin Beta-4 fragment | Illegal to possess without a script | Schedule 4, Appendix D clause 5 | Prescription only and listed in Appendix D clause 5, so possession without a prescription is an offence. Thymosin beta-4 itself is listed separately on the same terms. |
| TirzepatideMounjaro | Approved, prescription needed | Schedule 4, Appendix L clause 2 | Prescription only. An approved medicine in Australia. Appendix L sets required advisory statements for labels and is a labelling control, not a possession restriction. |

What does "not scheduled" mean?
"Not scheduled" means the substance is not named anywhere in the Poisons Standard, and it is the most misread status on this page. It does not mean approved, and it does not mean unregulated. Scheduling is only one of the controls in the Therapeutic Goods Act.
Retatrutide is the clearest example. It is not in the Poisons Standard because it is still an investigational drug that has not been approved as a medicine anywhere in the world. Being unscheduled is not a gap in the rules that makes it available. It means there is no approved supply chain for it at all, so anything sold under that name reached the seller outside the system entirely.
Can you buy peptides legally in Australia?
You can buy a peptide legally in Australia if a doctor prescribes it and a pharmacy dispenses it. That route is real and it covers approved medicines like semaglutide and tirzepatide, and compounded preparations where a prescriber decides they are appropriate.
What that route does not cover is the research-chemical market. A vial labelled "for research use only, not for human consumption" is not a different legal category of product. It is the same scheduled substance with a label that attempts to sidestep the fact that supplying it for human use is unlawful. The label describes an intention, not a status, and the Poisons Standard does not recognise it as an exemption. Ourclinics and prescribers page covers the lawful route.
What about importing peptides for personal use?
Importing a peptide for personal use still requires an Australian prescription. The Personal Importation Scheme is the pathway people usually have in mind, and it is narrower than the forums suggest. For anything in Schedule 4, the TGA's conditions are that you hold a valid prescription from an Australian-registered doctor at the time of importation, that a single order covers no more than a three month supply at the maximum prescribed dose, and that you import no more than a fifteen month supply in any twelve month period. Importing more than three months at once requires a doctor to apply to the TGA under the Special Access Scheme on your behalf.
Read those conditions together and the scheme does not do what it is often assumed to do. It is a route for a patient to obtain a medicine a doctor has already prescribed. It is not a route to acquire something you do not have a prescription for, which is the reason most people are asking about it.

How we checked this
Every status on this page was read from the current Poisons Standard instrument directly, on 1 August 2026. We record the instrument version because the Poisons Standard is remade roughly every four months, and a compound's status can change between editions.
That matters more than it sounds. While building this page we found the claim that Melanotan II had been reclassified as a prohibited substance repeated across several Australian peptide sites. It is not true in the current Poisons Standard, where Melanotan II sits in Schedule 4 and is not in Appendix D at all. Anyone relying on those pages has a worse picture of their legal position than the law actually gives them.
We are not clinicians, we sell nothing, and no listing here is paid for. Our editorial method sets out what we will and will not publish, including why there are no dosages anywhere on this site.
